OMX module

The optical multiplexer (OMX) module is a multiplexer and demultiplexer capable of supporting up to four wavelengths (one band).

Each OMX module contains passive optical filters that add and drop up to four channels in the assigned wavelength band. The OMX module can multiplex four wavelengths (channels) into an optical band. The bands can then be optically combined into a single optical fiber and can be added to other bands in an optical fiber path. See Figure 2-23.
