Mixed Analog-Digital WDM Local Area Networks

Abstract

In WDM avionic LANs, the severity of performance degradation due to multipath interference (MPI) is dependent on the type of transmitter and the signal spectrum, and it is difficult to generalize about its effects without detailed knowledge of the system (Darcie, et. al., 1991). However, the use of low-return loss angle-polished connectors coupled with stringent connector cleaning procedures is expected to reduce MPI to a tolerable level. Therefore, the remainder of this paper will discuss the second linear effect that must be considered in the design of avionic LANs, namely component crosstalk
