Optical Fibre Distribution Frame (GPX28D-GB)

This product is used to connect and schedule optical fibre and cables. It acts as a connection point between optical transmission networks and optical transmission equipment, or between access networks’ optical fibre and subscribers' optical cables. Supporting both cross connection and straight connection, it permits fibre connection, allocation, and scheduling.
  • Standard 19" installation, half-open structure, strong dust-proofing performance.
  • All operations at front, multiple frames can be arranged in a row, back to back, or against the wall.
  • Uses a 12-core splicing-distribution integrated module which can be removed.
  • Cables can be introduced from both above and below (optional).
  • Uses FC, SC, and LC adapters, applicable to ribbon and bundle cables (optional).
  • Adapter with 35° angle, ensuring proper bending radius of optical fibre.
  • Cabling space in base; inter-frame layout of optical fibre jumpers supported.
  • Complete set of reliable cable fixing, stripping, and grounding parts available.
