Breakout or Distribution Cables — Which One to Choose?

Cables with multiple fibers are widely applied to high-density indoor or outdoor installations. Breakout and distribution fiber optic cables are the common used types. However, people may mix them together because they have a similar outer appearance. Actually, the inner structure of these cables are totally different. In this article, some differences between breakout and distribution cables will be discussed.

Cable Structures
Breakout Cable Structure

Breakout cable is also known as fan-out cable. As the following picture shows, breakout cable consists two or more simplex cables bundled around a central strength member. Each fiber has its own jacket and all of the fibers are packaged together inside the same outer jacket. Thus, breakout cable can also be broken out into individual simplex cables for separate use when running through walls of a building. Breakout cable is usually designed with tight buffer and the fiber counts are varied from 2 to 24 fibers.

Distribution Cable Structure

Unlike the breakout cable, distribution cable is smaller in size and lighter in weight. Fiber counts of distribution cable can be more intensive than the breakout cable for up to 144 fibers. Many fibers may not be used immediately but can be left for future expansion. Although the distribution cable has a more compact design, the tight-buffered fibers inside the cable are only bundled in a single outer jacket for protection, as shown in the picture below. Yet this has made the distribution cable to be easily handled and stripped for field termination.

Cable Types
Types of Breakout Cable

According to different fiber ratings, breakout cable can be divided into breakout riser cable and breakout plenum cable. Breakout riser cable is widely used for vertical riser and general horizontal applications. However, when the cable is needed for ducts, plenums and other spaces with environmental air returns, breakout plenum cable is the better choice.

Types of Distribution Cable

Likewise, distribution cable also has the riser and plenum cable types for riser and plenum spaces deployment. Apart from these types, distribution cable is sometimes equipped with armored jacket for a stronger protection. Armored distribution riser or plenum cable can be applied to harsh premise environments where heavy-duty protection is required.

Cable Applications
Breakout Cable Applications

Breakout cable may end up in communication closets, and users can manually change connections. It is also available to be used for direct connection to the device. Moreover, breakout cable is suitable for short riser or plenum areas and conduit runs, where a very simple cable run is planned to avoid the use of splice box or spliced fiber pigtails. Since breakout cable has a stronger design, it is ideal for industrial applications where ruggedness is needed.

Distribution Cable Applications

Distribution cable is typically used for fast installation and easy termination of outdoor and indoor applications. It supports high performance networks and its single-unit fiber design saves much space. Distribution cable usually ends up at patch panels or communication closets, where they are connected with devices for communications between separate offices or locations. Distribution cable is also used within buildings to provide high-density connectivity for applications of intra-building backbones, routing between telecommunications rooms and connectorized cables in riser and plenum environments.

Conclusion

In summary, it is a convenient solution to use breakout or distribution cables for multi-fiber applications. Certainly, when you have to make a choice between them, you also need to consider the price factor. Breakout cable is generally stronger and larger than the distribution cable, thus the cost will be more expensive. Be sure to have a second thought before making the decision.

Advantages of Good Home Network

A good home network is beneficial to the visual neatness. House will be more tidy when less cables are exposed to the surface. Most wires will be installed through the walls. Possibility of cable mess is greatly reduced and you don’t need to be nervous about tripping over by the cables. Constructing a good home network also increases the value of the home. If the house is for sale in the future, a built-in network can certainly raise the price potentials. In addition, when setting up the network, you can add some aesthetic designs to your house like painting the wall into a new color or moving wall plates to appropriate places.

Different Network Connections

There are generally three types of home network connections. Choosing a suitable type for the network is also important.

Ethernet/LAN

Ethernet or LAN network uses physical cables to plug into the LAN port of router or switch. The speed for Ethernet cables can reach up to 1 Gbps. The cable length usually runs up to 100 meters without any influence to performance. Using a wired network is more secure and reliable. However, if you want to totally get rid of the cabling mess, there are better alternatives.

wired network

WiFi/Wireless LAN

People nowadays are familiar about this wireless network. It is the network that operates through radio waves without any wires. The latest 802.11ac standard defines the WiFi network for the maximum of gigabit speed. Wireless network allows for easier access to mobile devices and is simple to be set up. However, the signal also has a limited range and is easily interfered by other devices or buildings.

How to Choose Between PLC & FBT Fiber Optic Splitters?

In FTTx and PON architectures, fiber optic splitter is an important component to share the optic network with multiple users. The basic principle of fiber optic splitter is to split one optic light beam into several parts at a certain ratio. According to different manufacture technologies, fiber optic splitters can be divided into PLC splitter and FBT splitter. You may wonder the differences of the two splitter types when making a choice between them. This article aims at helping you to understand their distinctions and make better decisions.

Basics of PLC & FBT Splitters
What Is PLC Splitter?

PLC refers to planar lightwave circuit. As a micro-optical device, PLC splitter uses an optical chip to split the input signal into various outputs. At the edge of the chip, there is a light circuit in ribbon form mounted on a carrier and fibers. PLC splitter typically adopts silica glass as the material of lightwave circuit and accepts different types of polished finishes. The substrate, waveguide and lid are three basic layers of the PLC splitter. For different applications, PLC splitters can be further categorized into different types including bare PLC splitters, blockless PLC splitters, ABS PLC splitters, LGX box PLC splitters, mini plug-in type PLC splitters, tray type PLC splitters and 1U rack mount PLC splitters.

What Is FBT Splitter?

FBT, or fused biconic taper uses the traditional technology to fuse several fibers together closely. Fibers are aligned by heating for a specific location and length. Fusion process will not stop until the parameters of the fibers reach the required standards. Since fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. Then a stainless steel tube covers the inner glass tube and is sealed by silicon. FBT splitter with ABS box is also widely used for different applications.

Differences Between PLC & FBT Splitters

PLC and FBT splitters may look similar to each other, yet they still have many differences when it comes to actual applications. Here will compare them from several aspects.

Splitting Ratio

Splitting ratio is decided by the inputs and outputs of a splitter. A PLC splitter is available with the splitting ratio of 1:64, which means one light beam can be separated into 64 splits at a time. However, FBT splitter is typically used for networks requiring the splitter configuration of less than 4 splits. When its splitting ratio is larger than 1:8, more errors will occur and cause higher failure rate. Thus, FBT splitter is more restricted to the number of splits in one coupling.

Wavelength Range

PLC splitter has a wider operating wavelength ranging from 1260 nm to 1620 nm, thus it can be applied to most of the applications in FTTx and PON networks. On the contrary, FBT splitter has a limitation only to be used for 850nm, 1310nm and 1550nm wavelengths. This leads to the unavailability of FBT splitter on other wavelengths.

Temperature Dependent Loss

Temperature dependent loss (TDL) of the splitter is affected by the manufacturing process and the sensitivity of device. Once the working temperature of splitter is out of range, insertion loss will increase and influence the performance of splitter. PLC splitter is able to work at the temperature of -40 to 85 Celsius degrees while FBT splitter can only work at -5 to 75 Celsius degrees.

Price

Owing to the complicated manufacturing technology of PLC splitter, its cost is generally higher than the FBT type. If your application is simple and short of funds, FBT splitter is definitely a cost-effective solution.

Conclusion

In this article, some differences between PLC and FBT splitters are introduced to help you choose the most suitable one for your network. Overall, PLC splitter has better performance and less limitations, but FBT splitter is less expensive to save more for the budgets. If you are still uncertain which one to choose, please consult a professional for help.
