COMMUNICATION NETWORK AND OPTICAL TRANSCEIVER

원문 (중국어)

The invention relates to a communication network comprising an Internet protocol (IP) network and an optical network, wherein the IP network defines an IP domain and comprises a plurality of IP network elements, wherein the optical network defines an optical domain and comprises a plurality of optical network elements and an optical network management system, which takes over control functions in the optical domain, and wherein at least one IP network element comprises at least one optical transceiver which is connected, via an optical path, to a dedicated optical network element. In an in-service mode, the optical transceiver, is configured to convert downstream optical traffic included in a bidirectional optical service channel, which is received from the dedicated optical network element and destined for the IP domain, into IP traffic that is further processed by the at least one IP network element and to convert IP traffic, which is received from the at least one IP network element and destined for the optical domain, into upstream optical traffic included in the bidirectional optical service channel that is fed to and further processed by the dedicated optical network element. According to the invention, the at least one optical transceiver is configured to be switchable between an authentication mode and the in-service mode and to communicate with the optical network management system using a transceiver management channel. The at least one optical transceiver and the optical network are configured to establish the transceiver management channel, in the authentication mode, at least between the at least one optical transceiver and the dedicated optical network by using a dedicated management wavelength out of band with respect to service wavelengths reserved for all optical service channels in the optical network. Further, the invention relates to an optical transceiver which is configured to realize such a communication network.
