Page 14: Theory Of Operation
See Figure 11. Figure 11: Coarse Wave Division Multiplexing Lantronix CWDM devices utilize thin-film filter technology. Since the CWDM devices are entirely passive, they can be used in conjunction with lower-cost, noncooled laser sources. These CWDM devices are available in two main configurations: Multiplexer/Demultiplexer (Mux/Demux) modules, and Optical Add/Drop Multiplexer (OADM) modules. -
