Optical node configuration apparatus

摘要

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.

主权项

1. A configuration module for insertion into an optical node circuit board, including:
a housing having a first set of terminal pins and a second set of terminal pins for conductive contact between individual traces arranged on the optical node circuit board and selective contact with each of a first set of four passive traces and a second set of four passive traces respectively; a jumper switch for selectively connecting the first set of four passive traces to splitting and combining elements in segmented traces across arrayed across a base; the first set of four passive traces, when the configuration module is inserted in a first orientation conductively engaging the first set of terminal pins with the individual traces, splitting and combining elements, the splitting and combining elements being selectively connected to enable one of a group of conductive configurations including 1×4, 2×2, and 2+2 configurations, the splitting and combining elements including:
three splitting or combining elements; andtwo operational amplifiers; and the second set of four passive traces that when the configuration module is inserted in a second orientation at right angles to the first orientation, conductively engaging the second set of terminal pins with the individual traces in a 4×4 configuration within the configuration module.
