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 (). Stable and reliable, filter WDMs have wide bandwidth, low insertion loss, high isolation, and low temperature-dependent loss. An ultra-compact 1310/1550 nm wavelength division (de)multiplexer based on a channel-shaped multimode interference structure was proposed and fabricated on an InP platform. These components have been extensively used in EDFA, CATV, WDM networks and fiber.

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) regenerators, which they have made pra
