DWDM Device

VSunlight’s DWDM series single-channel DWDM are three-port filters that are used to add/drop a DWDM wavelength to/from a set of DWDM optical wavelengths, where the wavelengths are CH20, CH21. . . . . . CH62 on the DWDM ITU grid (0.4 nm or 0.8 nm spacing). The filters are available in different versions of packaging, like SUS tube or glass tube only. All versions are designed for using in an outdoor environment within a temperature range of –40℃ to +85℃.
