Fiber Optics Applications in the SHIPBOARD Data Multiplex System.

摘要

For a nominal size Shipboard Data Multiplex System (eight area multiplexers) using a passive tee coupler configuration, the connector and coupler excess losses for each coupler must total no more than 1.8 dB, which appears to be well within the state of the art. For a maximum size system (sixteen area multiplexers) the per coupler losses must be reduced to about 0.5 dB or less, which probably can be achieved given sufficient development effort. Two other devices, the passive star coupler and the fail-safe active tee coupler, also appear to have development potential for use in both nominal and maximum size systems. (Author)
