Fiber optic terminal box generally refer to the box shape fiber optic management products used to protect and distribute the optical fiber links in FTTH Networks. Usually the fiber optic boxes include the optical distribution frame and fiber optic terminal box. In general, fiber terminal box is for a few closed cores, and the open type is called ODF (optical distribution frame). Fiber termination boxes can be with 12 cores or 24 cores.
Fiber optic termination box is used to connect the two sections of fiber optic cable. The termination box is the access to the place of the ends of the cable, and then connect to the optical switches via the fiber patch cables. Therefore, the terminal box is usually installed on a 19-inch rack, and can accommodate a number of cable ends. Fiber terminal box is similar with cross connect cabinet, but the role is different. Cross connect cabinet is to connect tow fiber cables, while the terminal box is used to connect the fiber cable terminal with the pigtails with a protective effect. In practical work, roles of cross connect cabinet and fiber termination boxes are different, cross connect cabinets are divided into fiber cable cross connect cabinet and copper cross connect cabinet, which are used when front cable premising, while fiber termination boxes are used for protecting the cable terminal from external damages. Optical distribution frame can also be divided into fiber optic patch panels and copper patch panels, they are the same role with cross connect cabinet, but they are used indoor of carriers’data center.
Applications of fiber termination boxes is universal, they are widely used in telephone, agricultural telephone network system, data and image transmission system, CATV cable television series, indoor cable through force access and branch connection, played the role of the pigtail disk storage and protection of joint.
Actually there are too many fiber optic boxes and fiber management devices, they are hard to count the types, many fiber termination box manufacturers like Ingelen Technology will make the fiber optic boxes according to their own design and they may give the fiber optic boxes different names and model numbers.
