Product Description

1 * 4 mux demux CWDM insert type
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.
