Fiber Optical termination box is the terminal joint of a fiber, for it is fiber at one end and another is pigtail.
The box which was fixed on the wall is used to provide the welding of fiber optical and fiber, the welding of fiber optical and pigtail, as well as the transition of optical connectors. It also provides mechanical and surrounding protection of the fiber and allows proper inspection which maintains a high standard management of it.
The rack-mounted fiber optical termination box is mainly used to fixed the terminal of optical fiber. spliced the optical fiber and pigtail as well as installed on the 19 inches frame which could accommodate a comparatively bigger number of fiber.
