Everything you need to know about branch cables

As more and more data centers are upgraded to high speeds, they need greater flexibility to allow incremental network upgrades and strategies to avoid system failures. Branch cables are a solution that reduces risks, lowers operating costs, and provides high-speed, greater upgrade flexibility and robust design for data centers and more applications.

 

Structure
Branch cables (also known as fan-out cables) are composed of two or more single cables, which are bundled together around a central reinforcement. Each optical fiber has its sheath, and all optical fibers are encapsulated within the same outer sheath. Therefore, when passing through the walls of buildings, branch cables can also be divided into separate simplex cables for individual use. The branch cables are designed with tight buffering, and the number of optical fibers ranges from 2 to 24.

 

Characteristics and advantages
The term "branch" defines the main uses of branch cables. That is to say, a person can "disconnect" several optical fibers at any position and route the others to other places. For this reason, branch cables have been or should be encoded for easy identification. It features excellent tensile strength. The stranded FRP reinforcing component structure and aramid yarn as additional reinforcing components ensure the provision of good tensile strength, firmness and rigidity. In addition, branch cables offer high-density, high-speed connections, flexibility, easy installation and low cost.

 

Application
Branch cables are highly suitable for applications where optical fibers are directly connected to equipment, including local data centers, local area networks (Lans), indoor, backbone and horizontal, risers, booster rooms, conduits and industrial applications. In addition, the robust design of the branch cable makes it highly suitable for use as an introduction cable.

 

Conclusion
Branch cables are the preferred choice for those who need sturdy cables or direct termination without the need for junction boxes, junction boards or other hardware. In addition, branch cables offer a robust design, high density and high-speed connections, making them suitable for conduits, risers, booster chambers and industrial applications.
