Dense Wave Division Multiplexing (DWDM) technology has been popular in recent years due to its features of high density, high speed, and high capacity. OPTINET manufacture 100GHZ/50GHZ Grid SFP+, XFP, SFP modules, distance from 20km, 40km, 80km to 100km.
DWDM wavelength as specified by the ITU-T, from 1528.38 to 1536.86 nm (channel 17 to channel 61). Channel spacing can be 0.4nm, 0.8nm and 1.6nm. It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs) etc.
