Fibre-optic (FO) transmission traditionally is present in long haul backbone and metropolitan area networks.
 
However, since increasingly more fibre becomes available in campus-based and local loop infrastructures, fibre optic transmission becomes also important as a method for the direct connection of traditional end-user applications.

 

The equipment in this section offers a flexible way for the connection of a
variety of applications by different types of fibre media.
 
The units support applications based on serial connections, G.703 connections or Ethernet at speeds ranging from 64 kbps up to 45 Mbps.
