It is widely adopted in FTTx cabling for both fiber cabling, provides the connection between fiber optic cables and passive optical splitters. The fiber distribution box, a. The internal structure of a fiber optic electrical box (commonly referred to as a fiber distribution box or ODF box) is usually designed to be both compact and efficient for the management and maintenance of the fiber. Minimize the interference of the optical cable access signal to the external environment. As an important node in fiber optic access networks (such as FTTH) and backbone networks, it ensures efficient transmission. Its main function is to safeguard the connection point of the optical cable to the user end, ensuring that the access point of the optical cable remains stable, dust-proof, and waterproof.
