CWDM-3PORTS

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. 3C-LINK 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.
