Product Details
Company Profile

Dense Wavelength Division Multiplexing DWDM Device High Isolation

DWDM bare device 1270~1610 nm wavelength high isolation

Description:

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

Low PDL

Compact design

Good channel-to-channel consistency

Wide working wavelength: 1270-1610nm

Wide operating temperature: -20 ℃ ~ 70 ℃

High reliability and stability

Application:

CWDM system

PON network

Cable chain
