Abstract
Method and apparatus of an optical routing system ('ORS') capable of automatically discovering intra-nodal fiber connections using a test channel transceiver ('TCT') are disclosed. ORS, in one embodiment, includes a set of reconfigurable optical add-drop multiplexer (“ROADM”) modules, intra-nodal fiber connections, add-drop modules, and a test module. The ROADM modules are able to transmit or receive optical signals via optical fibers. The intra-nodal fiber connections are configured to provide optical connections. The add-drop modules are able to selectively make connections between input ports and output ports. The test module containing TCT is configured to identify at least a portion of intra-nodal connections of the ROADM via a test signal operating with a unique optical frequency.
