How Much Do You Know About Gigabit Ethernet Switch?

In computer networking, an Ethernet switch connects multiple devices, such as computers, servers, or game systems, to a Local Area Network (LAN). Small business and home offices often use an Ethernet switch to allow more than one device to share a broadband Internet connection. A gigabit Ethernet switch operates in the same way, only differentiating in data rates. Gigabit Ethernet is much greater than standard or Fast Ethernet. People can use these switches to quickly transfer data between devices in a network, or to download from the Internet at very high speeds. Gigabit Ethernet transmits at approximately one gigabit per second. That is at speeds nearly 10 times those of Fast Ethernet, which transfers data at approximately 10 megabits per second. The gigabit Ethernet switch is designed to work at these increased speeds, without signal loss or transfer rate reduction.

Gigabit Ethernet Switch: Managed or Unmanaged?

Gigabit Ethernet switches are either managed or unmanaged. Usually an unmanaged switch is referred as a “dumb switch”, which can be easily operated by every noob. It behaves like a “plug and play” device. A basic unmanaged gigabit Ethernet switch has no user configuration. It is placed in the network with the cables plugged in and the unit turned on, and there is nothing else to do. In contrast, a mangaed gigabit switch can be configured, and can be monitored and adjusted at your discretion, such as adjust speeds, combine users in subgroups, monitor traffic and report network activity. Although a managed switch is typically more expensive than an unmanaged switch, it offer much greater flexibility.

Gigabit Ethernet Switch or Ethernet Hub?

Although an Ethernet switch is sometimes called a hub, because a switch performs the same job as a hub, there is a huge difference between a true hub and a gigabit Ethernet switch. An Ethernet hub is a device that connects multiple Ethernet devices to a single network. A hub does not gather information and input in one port results as an output in all ports on the network. While a gigabit switch is considered as a more intelligent hub, because it gathers information about the data packets it receives and forwards it to only the network that it was intended for.

Gigabit Ethernet Switch Recommendations

A gigabit Ethernet switch can be an inexpensive and easy way to expand your network in your home or small business. After probing into some parameters like brand, popularity, reviews and performance, here is a list of network switches including Ethernet switches for home, port gigabit Ethernet switches, cost-effective gigabit switches etc.

A Glance At Cisco Single Mode SFP Specification

SFP(small form-factor pluggable) transceivers compact, hot-pluggable transceiver used for bothtelecommunication and data communications applications. They are an interface with a motherboard, router, switch or optical media converter. Link connection into a fiber optic or copper cabling. SFP transceivers are designed to support SONNET, Fiber Channel, Gigabit Ethernet or similar standards. There are both multi-mode and single mode SFP transceiver types. There are also many vendors manufacturing SFP transceivers like major brand Cisco. Cisco SFP transceivers also have Cisco multi-mode SFP and Cisco single mode SFP transceiver types. The following text will mainly focus on Cisco single mode SFP.

An Outline of Cisco SFP Transceiver

The industry-standard Cisco SFP transceivers are mainly used to link equipment in telecommunication and data communications like switches and routers. They support applications like 2G/4G Fiber Channel, SONET/SDH Network, Gigabit Ethernet, High-speed computer links, and with CWDM and DWDM interfaces. Cisco SFP have many types, such as 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis. Among them, 1000BASE-T SFP operates on standard Cat 5 UTP copper cabling of link lengths up to 100 m; 1000BASE-SX SFP only operates on multimode fibers; 1000BASE-LX/LH SFP operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers; 1000BASE-EX SFP only operates on long reach standard single-mode fibers; 1000BASE-ZX SFP operates on long-reach standard single-mode fibers; 1000BASE-BX10-D and 1000BASE-BX10-U SFP operate on a single strand of standard SMF. So we can see that Cisco single mode SFP consists of 1000BASE-EX SFP, 1000BASE-ZX SFP, 1000BASE-BX10-D and 1000BASE-BX10-U SFP.

A Sketch of Cisco Single Mode SFP Transceiver

Cisco single mode SFP has much tighter tolerances for optics used. The core is smaller and the laser wavelength is narrower. This means that SMF has the capability for higher bandwidth and much longer distances in transmission. Cisco single mode SFP (SMF SFP) work mainly in 1310nm and 1550nm wavelength and is mostly used in long distances transmission environment reaching 2km, 10km, 40km, 60km, 80km and 120km. The color coded bale clasp and color arrow on label are generally blue, yellow or purple. And the color of compatible fiber optic patch cord is yellow.

Conclusion

From the above introduction, you must have a well understanding about Cisco single mode SFP. When choosing SFP modules, you should consider whether it matches the switch port and the cable you have prepared. If you have multimode cable, then you can choose 1000BASE-SX or 1000BASE-LX/LH SFP. If you use single-mode fiber cable, you should select what I’ve mentioned above. While if your cable is copper category, you have to use 1000BASE-T SFP such as GLC-T SFP. On condition that your budget doesn’t allow you to buy original brand module, you can buy the third-party optics from FS.COM with Cisco, Avago, HP and other compatible brands. All the optics have gone through test for 100% compatibility.

SFP-10G-SR-S vs SFP-10G-SR, Why Choose One Over the Other?

SFP-10G-SR is a popular 10G SFP+ optical transceiver in terms of quantity used. It is considered as the mainstream form factor of the 2017 market due to its matured technology and reduced price, even although 40G/100G optical modules are on the very top trend for enterprise and data center for the interconnection. But two years ago, Cisco introduced S-class optics such as SFP-10G-SR-S for enterprise and data center applications. For some web searchers, he will be recommended with SFP-10G-SR-S rather than SFP-10G-SR. But they almost share the same characteristics, so SFP-10G-SR-S vs SFP-10G-SR, why choose one over the other? Hope this post may give some clue.

SFP-10G-SR-S vs SFP-10G-SR: Similarity

Seemingly and technically, they don’t have much difference. SFP-10G-SR-S shares the same product specification with SFP-10G-SR. SFP-10G-SR is compliant with 10GBASE-SR standard. The Cisco 10GBASE-SR module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber, up to 300m link lengths over OM3 and 400m link lengths over OM4 cables.

SFP-10G-SR-S vs SFP-10G-SR: Similarity

Cisco SFP-10G-SR transceiver is hot-swappable input/output device which allows a 10 Gigabit Ethernet port to link with a fiber optic network. Because it is hot-swappable and MSA compliant, the Cisco SFP-10G-SR transceiver can be plugged directly into any Cisco SFP+ based transceiver port, without the need to power down the host network system. This capability makes moves, add-ons and exchanges quick and painless.

SFP-10G-SR-S vs SFP-10G-SR: Difference

According to Cisco, S-class optics are intended for enterprise and data center 10G and 40G applications This new set of optics does not display several unnecessary features for these applications, bringing about a more attractive price. That explains why SFP-10G-SR-S price is lower than SFP-10G-SR price.

Except the price, there are some other differences. SFP-10G-SR-S optics aren’t TAA certified. However, the non-S-class optics such as SFP-10G-SR are all compliant to TAA. SFP-10G-SR-S optics only have COM (Commercial temperature range: 0~70℃). However, the temperature range of SFP-10G-SR can be EXT (Extended temperature range: -5~85℃), IND (Industrial temperature range: -40~85℃) and Storage temperature range (-40~85℃). In terms of protocols, SFP-10G-SR-S optics use Ethernet only, they cannot use OTN (Optical Transport Network) or WAN-PHY (Wide Area Network Physics). Furthermore, SFP-10G-SR-S optics just have 10G and 40G applications so far which is specified for 10G and 40G enterprise and data center. Thus, if you don’t need any special features like extra tolerance for temperature, S-Class optics can save you a considerable amount of money.

SFP-10G-SR Price Comparison

Since equipment SFP-10G-SR vendors all rely on MSAs when designing their transceivers, every supplier can produce the transceiver modules with the same functions but with different prices. Unless you have a 100% requirement to buy Cisco, there are a lot of 3rd party compatible vendors out there that you can save a lot of money by using. Here is a price list from different vendors for you to choose from.

Vendor Model Brand Price
CDW SFP-10G-SR Cisco $693.99
Router-Switch SFP-10G-SR Cisco $262.00
Monoprice SFP-10G-SR Ironlink $136.75
10Gtek SFP-10G-SR 10Gtek $41.05
FS.COM SFP-10G-SR FS.COM $16.00

SFP-10G-SR-S vs SFP-10G-SR, Which Will You Choose?

Although SFP-10G-SR-S vs SFP-10G-SR, they share identical specification, there still are some minor difference. In most cases, SFP-10G-SR-S optics are recommended for 10G and 40G applications due to its low cost. both SFP-10G-SR price and SFP-10G-SR-S price is relatively lower according to the above chart, and they also enjoy good quality. If you need any third-party optical modules or fiber optic cables, give FS.COM a shot.

What Does Combo SFP Port Mean For Your Ethernet Switch?

To many noobs who are unfamiliar with the structure and functionality of Ethernet switches may get confused with Combo SFP ports. Combo SFP ports are often labeled obviously. You may have some questions in your mind like what is Combo port and how should I use with it. Since there are many Gigabit Ethernet ports and SFP slots on switches, you may ask whether I used these ports correctly? Don’t worry, this post aims to explain Combo SFP port for your reference.

SFP Transceiver

What Is Combo SFP Port?

A Gigabit Ethernet Combo port is both a copper port, i.e. a RJ-45 interface and a SFP port (also called Mini-GBIC connector). It supports both copper (RJ-45) connections and optional industry-standard SFP modules. Combo SFP ports share the same switch fabric and port number and allow the user to configure their switch according to their application. But you can’t use both of them at the same time. When either of the ports are enabled, the other port is automatically disabled. It means that you can either have a cable plugged into the copper 10/100/1000 interface, or the cable plugged into the SFP slot. If you have both plugged in Combo ports, only one will work. For example, a switch has 12 x 10/100/1000Base-T ports and 2 Gigabit Ethernet Combo ports, therefore it could be configured to have 14 copper ports or 13 copper ports & 1 SFP port, or 12 copper ports & 2 SFP ports, etc.

A Combo port is a way to provide different types of connectivity without taking up unused switch fabric, giving users the power and flexibility to configure their switch for their unique application requirements.

Introduction to FS.COM 24-Port Switch With 4 Combo SFP Ports

There are many switches with combo SFP ports, such as Linksys LGS318 which is a 18-port Smart Gigabit Switch with two combo shared ports and Netgear ProSafe 24-port Gigabit Switch with 2 Gigabit Combo SFP—JGS524F. Today I’m going to recommend FS.COM 24-port switch with 4 Combo SFP—S3800-24F4S.

24 port switch with 4 combo sfp

S3800-24F4S 24-port Gigabit switch is designed to meet the demand of cost-effective Gigabit access or aggregation for enterprise networks and operators customers. The Combo SFP ports—a single interface with dual front ends (an RJ-45 connector and an SFP module connector) on S3800-24F4S 24-port switch facilitate the use of different connectivity, making it more flexible to configure the switch. It has a console port, 4 × 1GE Combo ports, 20 × 100/1000Base SFP ports and 4 × 10GE SFP+ ports. It offers up to 128Gbps switching capacity to simultaneously process traffic on all ports at line rate without any packet loss.

Conclusion

Generally speaking, Combo SFP ports are labeled by vendors. If you can’t tell, here is a way to help you identify. Identifying a combo port is based on the interface identifier on the switch panel. If two ports have the same ID but connect to different transmission media, the two ports are multiplexed as a combo port. Then you can run the display interface command to display the combo port. If you need any 24-port switch or any other Ethernet switch, welcome to consult FS.COM.

Armoured Cable vs. Unarmoured Cable: What’s The Difference?

With the rapid development of optical communication, more and more fiber optic cables are increasingly used in different environments. What if under harsh conditions? Then it’s crucial to ensure your cables smooth and reliable operation when transmitting data. This is where armoured cable comes into play. An armoured cable, as its name suggests, is protected against mechanical damage, whereas an unarmoured cable not being protected. What is the difference between them? And why should we choose armoured cable over unarmoured cable? You my find answer in this post.

Amoured Cable Overview

Armoured cable has an extra layer of protection to keep it from being cut or abraded. The armor layer of coax cable is a foil wrap that is ribbed like corrugated metal to allow for flexibility, around the inside and outside of that wrap is a flooding compound to keep moisture from penetrating the cable and causing an impairment. The internal structure of 4 core armoured cable consists of many layers to prevent the cable from damage. The outer jacket provides protection against rodent, abrasion and twist, which is usually made of plastic. And the armoring materials are mainly come from kevlar, steel, and aluminum foils, aiming to protect the armored cable from being stretched during installation.

the-structure-of-armored-cable

Difference Between Armoured Cable And Unarmoured Cable

Structure

Many people may think that armoured cable just has metal protection. To be precise, the armoring material doesn’t have to be metal, it can be fiber yarn, glass yarn, polyethylene etc. The only thing that makes armored cable different from unarmored cable is that the former has an additional outer protective layer for optical cable. The 4 core armoured cable tends to be more expensive than unarmored cable, while the armoured cable with steel strip and aluminum is much cheaper than armored fiber cable with Kevlar, which is usually used for special occasions.

Difference-between-Armored-Non-Armored-Cable

Application

Armoured cable is installed in locations exposed to mechanical damage, such as on the outsides of walls, as an alternative to conduit. Armoured cable usually has a small metal ribbon to ensure electrical continuity of the safety ground. (You must run a separate ground wire in flexible conduit too; you can’t depend on the continuity of the conduit.) In HT & LT distribution, 4 core armoured cable is preferred. Inside walls and in other protected locations, less expensive unarmored electrical cable can be installed instead. Unarmoured cable is mainly used for control systems.

Why Should Use Armoured Cable Over Unarmoured Cable?

There are a couple of reasons that armoured cable should be used. The biggest reason is about strength, because armored cable was used more extensively in past decades when cable was simply directly buried under dirt and not used through a conduit. Nowadays most local municipalities require conduits to be trenched in prior to installing network components, thus eliminating the need for unarmored cable in most applications. Secondly, rodents or animals can and will chew through cables so the armor protects the cables from damage by animal or shoveling in direct bury applications. Thirdly, the most uncommon reason it would be used is in an RF environment that has an off air RF signal that is powerful enough to interfere with your network, the armor when grounded can provide another layer of RF protection.

Conclusion

Armoured cable can be regarded as a kind of strengthened cable, which is harder and stronger than standard optical cable. With an unparalleled protection against physical damage without sacrificing flexibility or functionality within fiber networks, 4 core armored cable is a perfect addition to any fiber network in hazardous environments.

An In-depth Understanding Into Multimode Fiber Jumper

A multimode fiber jumper, also called multimode patch cable or multimode patch cord is one type of fiber optic patch cable mostly used for communication over short distances. Typical multimode fiber jumper can transmit data rates of 10 Mbit/s to 10 Gbit/s over 600 meters. Based on the types of multimode fiber, multimode patch cable can be divided into OM1 fiber, OM2 fiber, OM3 patch cable, OM4 fiber and the newly released OM5 fiber. What is exactly multimode fiber jumper and what are the applications of them? You may know multimoder fiber jumper better after reading this post.

What Is Multimode Fiber Jumper?

Multi-mode fiber jumpers are described by their core and cladding diameters. There are two kinds of core sizes: 62.5/125 µm. 50 µm and 62.5 µm refer to the diameters of the fiber core, which is the area that carries light signals. 125 µm means the cladding diameter of the fiber (a strand of human hair is about 100 µm). The fairly larger core of multi-mode fiber jumpers enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion.

OM4

Types of Multimode Fiber Jumpers

According to the type of paths that the light rays, or modes, multimode fiber jumpers can be categorized into step-index and graded-index multomode fiber. Step-index fiber is a fiber in which the core is of a uniform refractive index and there is a sharp decrease in the index of refraction at the cladding. The core of a step-index fiber has a uniform index of refraction right up to the cladding interface where the index changes in a step-like fashion. Unlike step index fiber, a graded index core contains many layers of glass, each with a lower index of refraction as you go outward from the axis. The higher refractive index at the center makes the light rays moving down the axis advance more slowly than those near the cladding.

Identified by ISO 11801 standard, multimode fiber jumpers can be classified into OM1 fiber, OM2 fiber, OM3 patch cable, OM4 fiber and newly released OM5 fiber. OM1 was first created in mid-80s. As gigabit and 10 gigabit networks have become widely used, an old fiber design has been upgraded. OM2 fiber was used from the late 70s with lasers for telecom applications. Laser-optimized OM3 patch cable or OM4 fiber today is considered by most to be the best choice for multimode applications. OM3 patch cable and OM4 fiber can provide sufficient bandwidth to support 10 Gigabit Ethernet up to 300 meters. OM5 fiber can transmit 40 Gb/s and 100 Gb/s and reduced fiber counts for higher speeds.

types of multimode fiber jumper

By the materials of fiber optic cable jackets, multimode fiber jumpers can be divided into four different types: PVC, LSZH, plenum, and armored multimode patch cable. PVC is non-flame retardant, while the LSZH is flame retardant and low smoke zero halogen. Plenum is compartment or chamber to which one or more air ducts are connected and forms part of the air distribution system. Armored multimode fiber jumpers use rugged shell with aluminum armor and kevlar inside the jacket, and it is 10 times stronger than regular fiber patch cable.

Applications of Multimode Fiber Jumper

Multi-mode fiber jumpers are used to connect high speed and legacy networks like Gigabit Ethernet, Fast Ethernet and Ethernet. For many years, conventional OM1 and OM2 were widely deployed in premises applications supporting data rates ranging from Ethernet (10 Mbit/s) to gigabit Ethernet (1 Gbit/s). Also, they were ideal for use with LED transmitters. Newer deployments often use laser-optimized OM3 patch cable. OM3 patch cable provides sufficient bandwidth to support 10 Gigabit Ethernet up to 300 meters. And OM4 is suitable for distance up to 550 meters. OM5 wideband multimode patch cable has been released this year to support at least four low-cost wavelengths in the 850-950 nm range and transmit 40 Gb/s and 100 Gb/s and reduced fiber counts for higher speeds.

Conclusion

Through aforementioned description about multimode fiber jumper, hope you can have a clearer understanding toward it. Last but no least, fiber patch cables can sometimes be distinguished by jacket color: for 62.5/125 µm (OM1) and 50/125 µm (OM2), orange jackets are recommended, while Aqua is recommended for laser-optimized OM3 patch cable and OM4 fiber. And lime green for OM5 fiber. If you want either multimode fiber jumper or single mode fiber jumper, welcome to visit www.fs.com for information.

How Can We Benefit From 24-Port Managed PoE Switch?

When you search for PoE switches, there are many options popping out, and you’ll be trapped into a dilemma. How should I make a decision between managed switches and unmanaged switches? But most recommendations are managed switches. It seems like managed switches are superior to unmanaged switches. It’s true. Because its security features. They allow administrators visibility and control. But the benefits of managed switches are more than this. The following text will cover what managed switches can do and where 24 port PoE switches are used for your reference.

Why Should Choose Managed Switch Over Unmanaged Switch?

A managed switch can seriously expand the long-range flexibility of your network and it can adapt to changing priorities. As your organization grows, your business needs will continue to evolve. Having a device that can respond to the dynamic shape of your operation is a good investment. There are several reasons why a managed switch is recommended:

  • Managed switches have all the features of an unmanaged switch and additionally have the ability to configure, manage, and monitor your LAN. So this helps you to monitor and decide who should have access to your network and gives you greater control over data flow through your network.
  • If there is an unused port on your managed switch, you can disable that port or even apply MAC address filtering so as not to allow unauthorised users or devices to access the network by just plugging in. So you can secure your network connections and also protect any unused ports on your switch.
  • A major advantage of managed switches is the failover redundancy they add to your network, helping to achieve less network downtime. Managed switches incorporate Spanning Tree Protocol (STP) to provide path redundancy in the network. This provides redundant paths but prevents loops that are created by multiple active paths between switches.

Where Are 24-Port Managed PoE Switches Used?

What are some of the ways a 24 ports PoE managed switch can enhance your organization’s networking capabilities? We need not look any further than the devices these switches connect. Some of the many things a 24-port PoE switch may be used for are:

overview of PoE managed switch

Note: S1400-24T4F managed PoE switch comes with 24x 10/100/1000Base-T RJ45 Ethernet ports, 1x console port, 2x combo port, and 2x gigabit SFP slots.

IP Cameras

To power an IP megapixel camera network, you’ll need a total power per port of 30W. For a 24-Port gigabit PoE managed switch with a power budget of 360W, you can continue to add IP cameras until you reach your budget. If you have 2 SFP ports, you can also connect to multiple switches, as well.

PoE solution

PoE Wireless Access Points (WAPs)

PoE WiFi access points (WAPs) require roughly 30 watts per port for efficient functioning. When you adopt PoE managed switches, installation of controllers and access points is greatly simplified. You won’t need to provide separate power cables or install plugs near wi-fi locations. You’d simply run your Cat5e or Cat6 Cable from your HotSpot to your switch and leave it alone.

Thin Clients

According to wikipedia, thin client is a lightweight computer built to connect to a server from a remote location. It has a barebones design and rely heavily on servers, which allow customers to get access to virtual desktop applications. Furthermore, it help lower costs by about 97%. Since they can access applications, sensitive data and memory from a data center via a managed PoE switch, they have no hard drive.

Conclusion

Since a managed switch has much more advantages over an unmanaged one. It’s necessary for you to have a managed switch in your network. In many cases, future-proofing with a better PoE switch (with more ports) may actually be a much better investment than smaller switches that have fewer ports. Thus, 24 port PoE switch is recommended here.
