FTTH fiber optical terminal box, outdoor fiber optic termination box is used in wiring connection between optical cable and optical communication equipment, through adapter in distribution box, optical fiber jumper leads optical signal, realize optical wiring function, and can meet the optical splitter placed to achieve spectral function. The equipment is used as a termination point for the feeder cable to connect with drop cable in FTTX communication network system. The fiber splicing, splitting, distribution can be done in this box, and meanwhile it provides solid protection and management for the FTTx network building.
