- Product Description -
Coarse wavelength division multiplexer (CWDM) is a low-cost WDM transmission technology for metropolitan area network access layer. In principle, CWDM uses an optical multiplexer to multiplex optical signals of different wavelengths to a single optical fiber for transmission. At the receiving end of the link, the mixed signals in the optical fiber are decomposed into signals of different wavelengths with the help of an optical demultiplexer and connected to the corresponding receiving equipment.
- Features -
CWDM adopts thin-film filter technology with good wavelength stability. It can be configured and upgraded according to requirements. The port has low insertion loss, high isolation, performance stability and high temperature stability, The product has the characteristics of low insertion loss, high channel isolation, wide bandwidth and low temperature sensitivity. It is generally divided into 4-channel, 8-Channel, 16 channel or up to 18 channel coarse wavelength division multiplexers. Due to the requirement of low insertion loss of coarse wavelength division system, when there are many channels, the module can add jump chips to reduce the insertion loss of each channel. The common coarse wavelength division packaging forms include ABS box, lgx box and 19 inch 1U chassis packaging.
