Fiber Patch Panel Color Code

Data center is regarded as the heart of a company’s information, for the customer’s information, staff’s information and even the research information are stored here. When it gets into trouble, so does the business. Cable management is one of the issues that may affect the data center operation. While managing the cabling in data center, fiber patch panel color code is certainly included.

Overview of Color Code System

Color code is defined as a system that uses various kinds of colors to tell people something. The earliest application of color code is using flags for long distance communication such as flag semaphore communication. As our society and technology advanced, this method has been widely used in many fields, chemistry, telecommunication, and even the military. It became convenient to use different colors as signals for telling apart the confused or similar things. For example, the fiber cables in electronic installations. Color coding can help users easily distinguish whether the fiber optic cables is single mode cables or multimode ones.

However, different countries may use different color code standards. In Sweden, they introduced the S12 color code for micro cables and nano cables while Finland developed the color code called FIN2012. Fortunately, there is a global recognized standard named TIA/EIA-598 color codes.

Introduction of TIA/EIA-598 Color Codes Standard

The standard is developed by Telecommunications Industry Association.  It rules identification schemes for fiber optic cables, fiber units and other fiber equipment. Fiber optic cable is split into several strands. They are the single fibers in a large cabling. And in this way, there will be 24 individual strands. After the process, the strands are usually divided into 12 tubes. Each tube containing 12 strands is given a color. In telecommunication industry, all fibers should use recommended method based on the widely acknowledged standard for their individual details and unique color code.

2x 24-Port Patch Panels or 1x 48-Port Patch Panel?

Patch panel is a passive networking device that bundles multiple ports together. It is a simple and organized solution frequently used in connecting different computers, telecommunications devices, and external hardware to others. Though wireless internet connections is becoming more popular, the use of a patch panel can actually optimize the internet speed especially in data center. Using a patch panel to arrange the circuit, users just need to plug or unplug the proper patch cords. According to the numbers of ports, patch panels can be divided into 12-port patch panel, 24-port patch panel and 48-port patch panel. They are designed in accordance with specific cable type, such as Cat5e, Cat6, Cat6a and Cat7 cables.

What Are Patch Panel Ports?

The port, as a part of patch panel, is the connection point that allows data to enter or leave the panel. Each port is connected via an ethernet or a fiber cable, then sends signal to an outgoing port location. On market, most patch panels are equipped with 24 ports or 48 ports. Selection of different patch panels should be based on one’s actual need. In addition, the port number is limited by the room for placing but not other factors. For example, the requirement of port number must be confirmed when someone designs a LAN network, so as to use the suitable panel size.

24-Port Patch Panel

FS.COM produced the product high quality 24 Ports Cat6 Shielded feed-through patch panel. It is made for optimum performance with black color and materials of SPCC+ABS plastics.

This is a big factor when people buy patch panels. At FS.COM, the price discrepancy between 24-port patch panel and 48-port is slight. As a result, buying two 24-port patch panels is definitely more expensive than buying one 48-port product. Besides, the space for installation should be another consideration. Thus, considered in these two ways, chose the 48-port patch panel is better. And we must realize that network is always developing, so why not staying up to date and ahead of the curve by utilizing the benefits of 48-port patch panel rather than trying to keep up with the pace.

Conclusion

The two types patch panels are the cost-effective and easy-to-use cabling solution for modern data center. Choose 2x 24-port patch panels or 1x 48 port should based on your own need. FS.COM is your source for high quality patch panels covering different ports including 12-port, 24-port, and 48-port options.

Single Mode Fiber Distance

Fiber optic cable is the essential media in telecommunication system for transmitting information. According to different categories, while depending on fiber connectors, patch cable can be considered as LC fiber, FC fiber, SC fiber, ST fiber and so on, it is well known that fiber optic cable can be divided into single mode fiber and multimode fiber based on transmission paths. Today, we will learn more about the single mode fiber distance.

Single Mode Fiber Overview

Single mode fiber derives its name from the fact that it only allows one mode of light to pass through their core at a time. Commonly, single mode fiber is designed with a narrow core diameter of 8 to 10 micrometers, which is much smaller than multimode fiber of 50 or 62.5 micrometers.

Before we continue, we need to be clear that due to different mode of propagation, there is modal dispersion during the signal spreading. And transmission distance is greatly influenced by the dispersion. Luckily, because of the allowance of just one mode of light, single mode fiber have the ability to transmitting data for miles without losing too much data. Thus it can readily carry information for a longer distance than the light used in the multimode fiber.

single mode fiber

OS1 vs OS2

OS1 and OS2 are the two types of single mode fiber, here the term OS refers to optical single mode fiber. Both of them are suitable for Gigabit applications and have the same jacket color.

OS1 cable is indoor tight buffered fiber that is compliant with ITU-T G.652A or ITU-T G.652B standards. The attenuation of this type is 1dB per kilometer with a top transmission distance of 2 km at 10 Gigabit Ethernet. It works between 1310 nm and 1550 nm.

OS2 cable is outdoor loose tube fiber optic cable that comply with ITU-T G.652C and ITU-T G.652D specifications. It has an attenuation of 0.4 dB between 1310 nm and 1550 nm, with a maximum transmission distance of 10 km at 10Gigabit Ethernet.

Selection on Different Distances

Single mode fiber provides a greater transmission distance. When choosing the right fiber cable, the most crucial thing that must be taken into consideration is how far the cable could support. In addition, the transmission distance is also related to the optics that users apply in the equipment.

Technology Bandwidth Wavelength Distance
1000BASE-LX 1000Mbps 1310nm 10km
10GBASE-LR 10Gbps 1310nm 10km
40GBASE-ER4 40Gbps 1310nm 40km
40GBASE-LR4 40Gbps 1310nm 10km

According to the above form, we can clearly see that transmission distance varies greatly. At different transmission rate, the distance changes. Distance of single mode fiber can reach 40km at the speed of 40gigabit Ethernet, and it will be 10km with the speed of 10gigabit Ethernet. Thus, try to buy fiber cable of suitable length for your project based on your network speed and some other actual situations. Thus, try to buy fiber cable of suitable length for your project based on your network speed and some other actual situations.

Conclusion

Transmission distance of single mode fiber is an important factor when people set up a network especially in data center that requires data to deliver over long distances. FS.COM provides a number set of OS1 fiber, OS2 fiber, LC fiber, SC fiber and so on. The products have passed many quality system verification such as CE, FCC.

PDU vs Power Strip: What Is the Difference?

Power Distribution Unit (PDU) is a reliable and cost-effective device to deliver power from a UPS system, generator, or utility source to multiple equipment by a single input with multiple output outlets. Rack mount power strip is the most basic PDU. They both supply power to the cabinet. But they have some differences. What’s the differences of upgraded PDU vs power strip? Continue to read this article.

What Is PDU

A PDU is a device fitted with multiple outlets. A PDU delivers AC power from power source to severs. PDU can be installed into a big cabinet with a power cord to transmit electric power to the computers and networking equipment located within a data center. Power cord can power a network device or connect to the PDU and computer in a data rack or network wiring closet. And C13 power cord is the best choice for PDU. In general, PDU is developing all the time. In the beginning, PDU is a simply and cheap rack mount power strip and then become larger floor mount PDUs with multiple functions.                                           

Basic Introduction of Power Strip

Rack mount power strip is an electronic device that makes it possible for people to charge multiple electronic device at the same time. Power strip which we can also call it power bar or power board is a device with a block of charging stations. Power strip is often connected with the end of a flexible cable(a mains pug) and then you can plug it into the wall or other place. It has a long power cord that can be used anywhere. It is extremely convenient.

The Difference Between PDU and Power Strip

Application area

PDU can be installed in equipment racks which keep power within reach of rack mounted devices like severs, switches, routers, or cooling fans. The installation of PDU is more flexible and convenient which can be suitable for customer who is very strict about it. And PDUs are often used in data center, network closets and industrial environments. In addition, PDU can be for in-depth power management and monitoring. Power strip are widely used both at home and office for audio, video, computer system, appliances, lights, business and other appliances.

Electricity Consumption

Compared with power strip, PDU is designed more reasonable. It has more strict quality and standard. PDU can work over a long time without any problem. If you use PDU for a long time, you never worry about heat.

Safety

PDU has fundamentally eliminated the potential safety problems such as frequent power failure, burnout and fire caused by poor contact and low load. While a power strip fails to contribute functions what PDU can.

Conclusion

From this article, we know the basic knowledge about the PDU and rack mount power strip. Each kind of PDU can help data centers to improve monitoring and reduce operation costs. To choose basic PDU or other types of PDU, it totally depends on your own needs. If you want to purchase PDU, you can visit FS.COM.

FHX MTP/MPO-12 Cassettes vs. FHX MTP/MPO-8 Cassettes

With the increase of network throughput, 40GbE network has become widespread and 100GbE is also extensively deployed. Under this circumstance, traditional LC cabling can not meet the high speed and high density demand of the data center. Therefore, achieving higher transmission rates and finding suitable solutions for high density cabling become the top priority. The emergence of FHX MTP/MPO cassette is a quite good news to high density cabling, which not only serves as a perfect solution for high performance data transmission but also saves space in data center. Commonly used FHX MTP/MPO cassettes are FHX MTP-12 cassettes and FHX MTP-8 cassettes. This article will cover what are they and difference between them.

Overview of FHX MTP/MPO Cassettes

MTP/MPO cassette is widely used for high-density cabling in data centers. It is pre-terminated and pre-tested enclosed unit which can provide secure transition between MTP and LC, SC or MTP discrete connectors. And it is usually structured with LC, SC or MTP adapters on the front side of the cassette and MTP adapters at the rear of the cassette. FHX MTP/MPO cassette has three types: FHX MTP/MPO-12 cassette, FHX MTP/MPO-8 cassette and FHX MTP/MPO conversion module. Commonly used are the former ones.

FHX MTP/MPO-12 Cassettes vs. FHX MTP/MPO-8 Cassettes

As both Base-8 and Base-12 play an important role on the basis of MTP system, some network designers may ask “Will one cabling solution fit all applications? They don’t look much different?” Although they have the same function, and the only difference is 12 fibers vs 8 fibers, one cabling solution can’t fit all applications.

We know that Base-12 makes use of fiber optical links based on increments of 12 fibers and 12-fiber MTP fiber optic connector is common used. However, there is a problem when using Base-12 cabling solution—four fibers for transmit and four fibers for receive, leaving four fibers unused per connection. While Base-8 can be a more cost-effective option for end-to-end MPO to MPO channels and architectures. Deploying Base-8 connectivity in duplex architectures for 10GBASE-SR and 25GBASE-SR will save 4% to 5% for data center managers, but if you are running groups of 6-ports, Base-8 may result in a significant cost increase.

Network built with 8-fiber MTP system can transmit the same data with less cost and higher density compared with 12-fiber MTP system. All fiber will be 100% utilized in base-8 MTP products. It could be a cost-effect solution for both 40G to 40G transmission and 40G to 10G transmission. For more MTP/MPO base 8 vs base 12 link, you can read: 8-Fiber MTP VS. 12-Fiber MTP Cables

Conclusion

There are a variety of advantages of FHX MTP/MPO cassette modules. With the easy-installed design, it can greatly reduce the labor cost and save more space and time. In addition, it is easier for management and maintenance and has lower security risk. It satisfies the demands for high optical port density and system interoperability. Thus, it is more and more popular among users. MPO/MTP cassette modules can be used in both lower fiber count break out applications (e.g., server cabinets) and high fiber count interconnects by mounting in chassis. It is an ideal solution for interconnection or cross-connection in telecommunications networks, WDM applications, data center cabling, backbone cabling and 40/100G communication network.

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

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.

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.
