Experimental Demonstration of Signal Decoding Stability on Hybrid WDM/OCDM Add/Drop Node Module for Adaptive Network

In this letter, we demonstrate the decoding stability of an optical hybrid filter (OHF) node module for an adaptive network to an environment temperature fluctuation. [Error free] signal decoding was observed from a temperature range of 0° to 60°. Improving athermal mounting technology would expand the applicable temperature range of an OHF node module as the passive node.
