Normal WDM (sometimes called BWDM) uses the two normal wavelengths 1310 and 1550 nm on one fiber. Coarse WDM provides up to 16 channels across multiple transmission windows of silica fibers. Dense WDM (DWDM) uses the C-Band (1530 nm-1565 nm) transmission window but with denser. 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. With wide bandwidth, low insertion loss, high isolation, low temperature-dependent loss, and low polarization sensitivity, Lumentum filter WDMs are. This device is to combine or separate 1310nm and 1550nm band signal.
