18 ports FTTX Pre-connectorized Terminal Box PTB-18D Total enclosed structure

Share to:


The FTTX Pre-connectorized Terminal Box PTB-18D is used as a termination box 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. It can offer 18 FTTH subscribers access points.



  • Total enclosed structure.
  • Material:PC+ABS, wet-proof, water-proof, dust-proof, anti-aging, protection level up to IP65.
  • Clamping for feeder cable and drop cable, fiber splicing, fixation, storage, distribution…etc all in one.
  • Cable, pigtails, and patch cords are running through their own paths without disturbing each other, micro type PLC splitter installation, easy maintenance.
  • Distribution panel can be flipped up, feeder cable can be placed by expression port, easy for maintenance and installation.
  • Box can be installed by the way of wall-mounted or poled-mounted, suitable for both indoor and outdoor use.
