Dense Wavelength Division Multiplexing Module Standard
Dense WDM (DWDM) uses the C-Band (1530 nm-1565 nm) transmission window but with denser channel spacing. Channel plans vary, but a typical DWDM system would use 40 channels at 100 GHz spacing or 80 channels with 50 GHz spacing. Corning DWDM multiplexers and demultiplexers utilize advanced thin-film filter and athermal waveguide technology designed for low insertion loss, high isolation, and excellent temperature stability in a totally passive device. They are available in various channel counts at ITU industry standard. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. They. FS DWDM transceivers are available with C17-C61 100 GHz DWDM wavelengths, and C17-C61 50 Ghz DWDM wavelengths, including DWDM SFP, DWDM SFP+, DWDM XFP, and Tunable DWDM transceivers that support transmission distance up to 100 km. The present document is a revision of ES 201 791 V1.
