A segmented optical node exploits a configuration module having arrayed all elements to go from a 1�4 to a 4�4 configuration, save optional redundant switches. A jumper board in the 1�, 2� path configures the node for 1�4 in one orientation and for 2�4 when flipped around 180 degrees. The 4�4 configuration is achieved by rotating the configuration module 90 degrees. In this orientation power to the module is also off, since the 4� configuration is passive. |
