Most people don't actually really know about how fiber optic cable is terminated, or how important it is. A proper fiber optic termination is necessary and important when installing a fiber optic network. All residents in an apartment or offices in a building will be affected by an unreliable network if fiber optic cable doesn't install properly.

What is Fiber Optic Termination?

Fiber Optic Termination means terminates fiber optic cable, it means the connection of fiber optic cable to a device for end-users, such as fiber optic terminal box, fiber optic floor distribution box, fiber optic wall outlet, etc. These kinds of devices not only support fiber Splitting or Patching but also provide the ability to protect fiber optics from various weather influences and physical damage while in use. They are a very important part to make a network work and run properly.

When a cable enters a fiber optic termination box, the jacket around the fiber cable is removed, a part of exposed fiber optic will be separated and be fused and placed in the splice tray with pigtails inside fiber optic termination box, while the other part will keep going to the next fiber optic termination box for others end-user.

Cables are usually terminated in two ways: user connectors to Join two fibers to form a temporary joint or splicing (mechanical splice and fusion splice).
1) Mechanical splice means two fibers are not joined permanently, they are just precisely held together by a connector. This temporary solution has lower initial investments but higher costs for each splice.
2) Fusion splice As its name suggests, two fibers are fused together by a specialized device. This makes two fibers joined permanently and more precisely. Such a method has even lower losses on light transmission. This permanent solution has a higher initial investment (the specialized tool) but the very low cost on each splice.


Protecting Splices

Whatever the methods used to terminate fiber optic cable, splices require a splice tray to place and then placed in a protective case (known as fiber optic termination box) to protect splices from various situations, such as different weather, water, dust, impact, UV, etc. Although both mechanical splice and fusion splice are for joining two fibers together, and they both have their advantages, fusion splicing is much more widely used as it provides the lowest loss and lower cost per splice.
