Abstract ASON is the next step in the progress of optical trandmission technology. It provides the ability of connection’s dynamic setup and release by introducing the intelligence contol plane. The multigranular optical cross connect is the key equipment in ASON.It provides the connection function for optical channel.The two structure of MG-OXC are introduced and compared in this paper.The advantage of MG-OXC comparing to the ordinary OXC is introduced . It’s ability to support the control plane of ASON is also introduced.The evultion and trend of waveband and routing algorithm research are introduced in the last part.
Key words ASON; MG-OXC; Waveband
