ORTE 1270~1610nm CWDM Coarse Wavelength Division Multiplexing,ITU±6.5/7.0
CWDM uses optical multiplexer to multiplexe optical signals of different wavelengths to a single optical fiber for transmission. At the receiving end of the link, mixed signals in the optical fiber are decomposed into signals of different wavelengths by optical demultiplexer and connected to the corresponding receiving device. The CWDM device has the advantages of small size, low power consumption, easy maintenance and easy power supply. It can use 220V ac power supply. ORTE CWDM is widely used in telecommunications, radio and television, enterprise network, campus network and other fields.
