Bidirectional Transmission System For Tactical Applications

The long-wavelength fiber optic transmission system described in this paper uses a two-channel optical wavelength multiplex technique to provide simultaneous bidirectional communication over a 15 km length of optical fiber. The development of molded plastic expanded-beam connectors and state-of-the-art dichroic beamsplitters has made it possible to design simple optical wavelenth multiplex components that are well suited to meet the requirements of a tactical environment.
