3 Port CWDM Device
coarse wavelength division multiplexer takes advantage of thin film coating technology. And the devices combine and separate the optical signal at different wavelength.CWDM devices are mainly used in passive wavelength division multiplexing system module products, which can Mux, Demux or add-drop multiplexing different optical signals, meet the requirements of providing different rates of transmission channels transparent to the protocol on a single optical fiber, such as Ethernet, ATM, POS, SDH, etc., and are widely used in telecommunications, radio and television, enterprise network, campus network and other fields.
