  • AAA 111 High Isolation CWDM

    CWDM is a low cost WDM transmission technology for the metropolitan area network access layer. In principle, CWDM uses optical multiplexer to transmit optical signals of different wavelengths to a single optical fiber. At the receiving end of the link, the mixed signal in the optical fiber is decomposed to different wavelengths with the aid of optical demultiplexer, and connected to the corresponding receiving devices.
