The 4-core fiber termination box provides a stable, protective joint between optical cable and distribution pigtails at the end of fiber cables. It is typically used in cabling work area subsystems. It is widely adopted in FTTx cabling for both fiber cabling, provides the connection between fiber optic cables and passive. Inline Splice Closure Inline Splice Sleeeves are designed for use in long-distance fiber optic cable runs where splicing is necessary to repair or extend the network. With its total enclosed structure. The FTTH-006 is a floor mounted or wall mounted termination box for end user, indoor use, capable to handle fiber fusion,capable to handle fiber fusion, fiber cables and pigtails.
