Moreover, in terms of installation environment, there are indoor fiber termination box and outdoor fiber termination box. Indoor fiber termination box acts as the transition point between the risen cable and the horizontal cable, in this way, it provides operators much more flexibility when managing cables. Besides, indoor fiber termination box makes it possible to leave space for overlength and terminated fibers, as well as for fiber splicing. The outdoor fiber terminal boxes are environmentally sealed enclosures to distribute fibers for FTTX networks. They are also designed for fiber splicing, termination, and cable management. Fiber termination box contains the shell, the internals (supporting frame, set fiber disc, fixing device), and optical fiber joint protective element. Prominent advantages of fiber termination box lie in efficient cable-fixing, welding, and its protective role in machinery of the optical fiber. An insulation is always demanded between cable metal components and cable terminal box shell in a fiber termination box, which provides space for cable terminal and remained fiber storage. In addition, fiber termination box also facilitate the installation of different occasions since it is easy to access, which turns out to be time and cost saving. Recently, fiber termination box is universally used in telephone, agricultural telephone network system, data and image transmission system, CATV cable television series, indoor cable through force access and branch connection. Fiber termination box is available for the distribution and termination connection for various kinds of fiber optic systems, especially suitable for mini-network terminal distribution, in which the optical cables, patch cores, or pigtails are connected. In addition to that, fiber termination box can also be applied to joint fiber pigtail, protect fiber optic splices, and share out the connectivity to individual customers. Fiber termination box nowadays plays an indispensable role in the field of communication network with greater reliability and flexibility. This article may simply provide you a guideline when choosing fiber termination box for your infrastructure.
