Abstract

A system for exchanging optical signals between two separate locations. Each location is provided with a transceiver (10) that includes a transmitter and a receiver. Both the transmitter and the receiver are based on a transceiver unit (10), used as a transmitter unit in the transmitter and as a receiver unit in the receiver. The transceiver unit (10) includes a multimode optical waveguide (20 & 28) and imaging optics that collimates the light emerging from the waveguide and imaging optics (18) that collimates the light emerging from the waveguide in the transmitter implementation of the unit. The waveguide is terminated by a FC/APC (24) to suppress reflections at the waveguide/air interface. The common waveguides in turn are optically coupled to network interface units (58) at each location. Transceivers are aimed at each other to exchange optical signals between the two locations.
