Product Description:
Lightwit Photonics’ Coarse Wavelength Division Multiplexer (CWDM) is expanding the bandwidth of Metro/Access communications networks.
Lightwit Photonics’ CWDM is based on thin film filter technology and metal bonding micro optics packaging. Lightwit Photonics provides high quality CWDM with flat channel bandwidth, flexible channel configuration, low insertion loss and high isolation. It is designed to upgrade capacity easily as the system grows. All Lightwit Photonics products are epoxy-free in the optial path. Lightwit Photonics’ CWDM components provide an ideal balance of price and performance for multiplexing and dumultiplexing in Metro/Access networks.
