Multimode optical fibre assemblies

multimode cables

We can supply a wide range of specialist multimode cable assemblies to the tightest tolerances to give you the reliaibility and consistency you need.

  • Innovative - unusual combinations of connectors, fibres and cables
  • Reliable - 100% testing of insertion loss, return loss, end face geometry and surface finish
  • High performance - low insertion loss/ high return loss/ custom wavelengths
