ABSTRACT:
Optical signals may be communicated with A/V Bridging services between an upstream link partner and a down stream link partner, each comprising an asymmetric Ethernet optical physical layer (PHY). High bandwidth A/V optical signals may be transmitted from the upstream link partner and low bandwidth optical signals may be transmitted from the downstream link partner. One or more of a time stamp, a traffic class and/or a destination address may be utilized in generating PDUs and managing communications via the asymmetric Ethernet optical PHY. The receiving link partner may register for delivery of the PDUs. An aggregate communication rate may be distributed evenly or unevenly among one or more optical links for transmission and aggregated upon reception via asymmetric Ethernet optical PHY operations. Compressed, uncompressed, encrypted and/or unencrypted optical signals may be handled. Signal processing may comprise forward error checking and clock recovery.
