Optical patch cords

LC Patch cords with reduced bending losses Cor-X Flex



These patch cords are simplex or duplex pieces of cable of certain length and external diameter, terminated from both ends with connectors LC applying fiber, which complies with requirements of ITU-T G.657.A.



  • Small size and high-density positioning;
  • Ferule 1.25mm made from zirconia ceramics;
  • Low induced losses;
  • Low reflection;
  • Simplex and duplex variants are possible.


Colour marking:

Connector’s colour indicates the method of end surfacing :

  • Blue - surfacing type UPC (Ultra PC)
  • Green - surfacing type APC (Angle PC)


Patchcord colour indicates the type of used optical fiber:

  • Yellow - single-mode fiber


Fields of use:

  • Fiber-optic communication systems;
  • Fiber-optic data transmission systems;
  • Fiber-optic networks CATV;
  • Local area networks;
  • Global networks;
  • Terminals.
