Coarse Wavelength Division Multiplexer Remote Monitoring Authentication
Coarse wavelength-division multiplexing (CWDM), in contrast to DWDM, uses increased channel spacing to allow less sophisticated and thus cheaper transceiver designs.

Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (), or 1570–1610 nm ().

However, recent standardization and a better understanding of the dynamics of WDM systems have made WDM less expensive to deploy. A WDM system uses a at the to join the several signals together and a at the to split them apart. Originally, the term coarse wavelength-division multiplexing (CWDM) was fairly generic and described a number of different channel configurations.

Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (C band), or 1570–1610 nm (L band). EDFAs were originally developed to replace SONET/SDH optical-electrical-optical (OEO) regenerator. A WDM system uses a at the to join the several signals together and a at the to split them apart.

The terminal multiplexer contains a wavelength-converting transponder for each data signal, an optical multiplexer and, where necessary, an optical amplifier (EDFA). 's Enhanced WDM system is a network architecture that combines two different types of multiplexing technologies to transmit data over optical fibers. Shortwave WDM uses (VCSEL) transceivers with four wavelengths in the 846 to 953 nm range over single OM5 fiber, or two-fiber connectivity for OM3/OM4 fiber.
