Multiplexing SONET /SDH data streams using independent encoding schemes

摘要

A system for transparently transporting m synchronous data streams as an aggregate data stream on a single channel of a Wave Division Multiplexed (WDM) optical link without pointer processing uses m unique encoding schemes to enable recovery of the respective m data streams from the aggregate data stream. The encoding schemes are preferably self-inverting. The respective m data streams are parsed into data units and encoded. The data units are then interleaved to form the aggregate data stream. Recovery is accomplished using a reverse process.
