A trusted relationship service includes a certificate authentication server and a secure file host. The certificate authentication server operates to receive requests from a supplier and a customer to register with the service, verifies the identities of the supplier and the customer and sends digital certificates to both the supplier and the customer. The supplier can send information to the trusted relationship service where it is posted in a secure file host. The supplier can solicit the customer to visit the trusted relationship service web site to view the supplier information stored there, whereupon the customer can use their digital certificate to access the trusted relationship service site and is granted permission by the site to view the supplier information.

A communication system includes plural nodes interconnected with an optical transmission medium capable of carrying plural bands of optical channels. A device at each node is coupled to the medium for dropping one or more bands, adding one or more bands, and passively transmitting other bands such that a pair of nodes can communicate directly using a band common to the respective bands. One band of the bands associated with each of a first set of nodes overlaps with one band of the bands associated with each of a second set of nodes. Multiple overlapping bands provide a high level of wavelength termination diversity. An optical management bus system and method connects plural hybrid optical/electrical cables between transmission equipment and optical modules which connect to network fibers to provide a set of electrical connections that can be used to determine optical interconnections in an optical shelf configuration. A particular optical module can be identified as the root of an optical branching tree at a node and thereby the unique termination point of a network fiber such that a physical fiber topology can be associated with the logical fiber topology.
