Product Details

CWDM Device 

CWDM is short for Coarse wavelength division multiplexing. It is a technology of combining multiple signals on laser beams at various wavelengths for transmission along fiber optic cables. Transmission is realized using 18 channels with wavelengths between 1270 nm and 1610 nm. Due to the channel spacing of 20 nm cost-effective lasers can be used. The channel width itself is 13 nm. The remaining 7 nm is designed to secure the space to the next channel.

Optico Communication Co. Ltd. offers high performance CWDM Mux/Demux devices. They can suit all kinds of applications and network solutions. The CWDM mux/demux 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.

· Much lower cost per channel than DWDM

· Telcordia/Bellcore GR-1209 and GR-1221 qualified

· Easy to install and use
