Product Description

2 Channels CWDM Mux Demux 1270~1610nm Wavelength High Isolation
CWDM is a sort of multi-service processing and transmission device that designed especially for point-to-point applications.
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.
The device has broad passband and high isolation, makingit ideal for functioning with inexpensive, uncooled lasers.
