Tips on Buying Fiber Optic Cables

Buying fiber optic cables has been a daily thing in our life. Since the field of fiber optic network is still unfamiliar to most people, not to say the detailed information about the fiber optic cable. In this article, we are going to provide some tips for you to buy fiber optic cables. Before that, let’s go over the background information of the fiber optic cable for your better understanding.

What Is the Fiber Optic Cable

The fiber optic cable refers to a kind of telecommunication cable, containing one or more glass or plastic made optic fibers, usually slightly wider than a human hair. It can carry light to transmit data. Designed for long distance transmission from hundreds of miles to thousands of miles, the fiber optic cable is an ideal choice for networking, telecommunications and storage applications in wiring closets, distribution frames, gateways, central offices and data centers.

Types of Fiber Optic Cables

According to different standards or features, there are different types of fiber optic cables. Basically, based on different transmission modes, the fiber optic cable can be grouped into two types: single mode fiber and multimode fiber.

Single Mode Fiber

The fiber optic cable for this type is a single strand of glass fiber with a diameter of 8.3 to 10 microns, which is narrower than the multimode fiber. Under such a condition, the beam of light is transmitted in a much tighter space with a higher transmission rate. Therefore, it makes the long-distance communication, sometimes as far as between continents more available.

Multimode Fiber

Compared with single mode fibers, the multimode fiber has a larger diameter (62.5µm or 50µm), allowing more space to generate and collect light. Considering about multimode fibers’ transmission performance, it is mostly used for communications over short distances no longer than 2000 m, such as within a building or in a small campus.

Buying fiber optic cable is not so difficult as you have thought. After reading this article, we believe things will be different for you.

Fiber Optic Cable Core-How Much Do You Know About It?

For anyone who wants to know fiber optic cable core, it’s a must to know the structure of a fiber optic cable. For a fiber optic cable, it consists of three basic parts: the core, the fiber optic cable core cladding, and the coating layer outside the cladding.

What Is Fiber Optic Cable Core?

A conventional fiber optic cable core is a glass or plastic made cylinder running along the fiber’s length. This part is designed for light transmission. Therefore, the larger the core, the more light that will be transmitted into the fiber. As we mentioned before, the core is surrounded by the cladding layer to provide a lower fiber optic cable core index of refraction. So more light can be transmitted into the fiber.

Fiber Optic Cable Core Types

According to different standards or features, the fiber optic cable can be grouped into different types. For example, classified by connectors, we can get LC fiber, SC fiber, etc; classified by transmission mode, we can get multimode fiber and single mode fiber. Likewise, with different features, the fiber optic cable core can also be divided into different types.

Fiber Optic Cable Core Material

According to the material, plastic and glass cores can be found. When the core is made from pure glass, the cladding is from the less pure glass. Glass type has the lowest attenuation over long distances but comes at the highest cost. As for the plastic core type, it is not as clear as glass one but is more flexible and easier to handle. Moreover, the plastic type is more affordable for us.

Fiber Optic Cable Core Size

Based on sizes, the fiber optic core can be grouped into quite a lot of types. Basically, the most common core sizes are 9 µm in diameter (single mode), 50 µm in diameter (multimode), 62.5 µm in diameter (multimode). For your better understanding, please look at Figure 2 as below. It’s a comparison of the three common sizes when they are inside the same cladding layer diameters (125 µm).

Fiber Optic Cable Core Numbers

Featured by how many cores in fiber optic cables, two kinds of cable cores can be arranged: the single core and the multicore. The single core type refers to the fiber cable that consists of a core and a cladding layer, which is the most common type in the market. However, the multicore fiber optic cable means that in the same cladding layer, there are more than one core in it. The commonly used cables are four, six, eight, twelve, twenty-four cores.

How to Connect Fiber Optic Cable to Fiber Optic Patch Panel

Fiber optic cable is usually terminated in two ways. One is using connectors that pairing two cables to set up a link, and the other way is connecting the fibers to some network equipment such as fiber optic patch panel or switch for better cable management. No matter which terminations it uses, fiber optic cable should be installed in a manner with less signal loss. However, how to connect fiber optic cables to fiber optic patch panel correctly? Today, we will talk about the steps of this process. First, let’s have a overview of patch panel.

Types of Patch Panel

Patch panel is defined as the interface between multiple optical fibers and optical equipment. It’s a termination unit that helps networking and fiber distribution from wiring closet to various terminal equipment. Patch panel are divided into two types based on different designs, the wall mount and rack mount category. Both types can house, organize, and protect fiber optic cable and connectors.

Wall mount fiber patch panel is usually fixed on indoor walls with low-profile and compact design. It has a terrace that can provide a flexible cabling system. This patch panel is a suitable device for on-site installation of pre-connected cables and connectors.

Rack mount fiber patch panel is an indoor network equipment which is designed for standard 19 inch rack mounting. It’s available in 1U, 2U and 4U size due to different connection demands. This type can accommodate all kinds of fiber adapter ports like SC, LC, ST, FC and so on.

Structure of Fiber Optic Patch Panel

A typical fiber enclosure consists of four elements with different uses. They are enclosed chamber for installing adapter panels for holding, connector adapters for mating and splice tray for organizing. Thus, technicians can use a fiber optic patch panel to terminate fiber optic cables in a tidy and secure way. In addition, with assistance of a patch panel, they can also install, repair and upgrade networks quickly and efficiently.

Steps of Connecting Fiber Optic Cable to Fiber Optic Patch Panel

It’s important to make a right connection between cables and fiber optic patch panel so that the device can run well. Following the steps, you can do it.

  • A fiber optic patch panel should be prepared first and make sure this work will be done on a clean and level work surface. Patch panel is supplied empty, so the adapters should be inserted into the mounting plate. Then fix the mounting plate in position.
  • Prepare cables based on standard termination procedures and ensure there is enough surplus cable to work with. Connect the cable by fixing the gland and roll the excess fiber onto the spool. After that, remove the protection cap and insert into position in the adapter. Once the cables are all attached, it’s better to use a zip tie to secure the cables in a bundle.
  • Label each jack location on the fiber optic patch panel so as to distinguish the cables. Finally, mount the patch panel in a rack or cabinet.

Conclusion

Fiber optic patch panel is a cost-effective way for cable management. Connecting fiber optic cable to patch panel is easy and can actually optimize the network work. So why not have a try?

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.

Benefit of Using Color Code

Better cable management is the best benefit of fiber patch panel color code. In data center, there are always brunches of cables and facilities. When the configuration of network or cabling needs to be changed for introducing new or more devices, the technicians have to spend large amount of time to deal with the chaotic cables. But now, with the help of fiber patch panel color code, just at a glance, the technicians can easily and quickly tell apart which cable should be unplugged or connected. It’s not only a perfect way to increase efficiency for technology workers who are responsible for installing, troubleshooting and maintaining the network, but also an effective mean of saving staff’s time so that they may go home on time.

Conclusion

Fiber patch panel color code simplifies network management by providing a visual identification of every cable. This cost-effective and easy-to-use method can help users route cables in an easier and more accurate way, reducing network errors and making maintenance easier. FS.COM always remains focused on researching and developing ways for a better network.

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.

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.
