Coarse wavelength division multiplexer (CWDM Mux) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provides low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.
CWDM is using optical multiplexers to reuse different wavelengths of light into a single fiber to transmit signals.
At the receiving end of the link, the mixed signal is decomposed into signals in the fiber by means of an optical demultiplexer.
Different wavelengths are connected to the corresponding receiving equipment.
Features :
Low insertion loss
High isolation
Compact design
Good channel-to-channel consistency
Wide working wavelength: 1270-1610nm
Wide operating temperature: -20 ℃ ~ 70 ℃
High reliability and stability
  • Line monitoring
  • Telecom munication
  • Cellular Application
  • Fiber optical Amplifier
  • Access Network
