The model 907 series of CWDMs combine multiple media converters or multiplexer motherboards onto a single fiber-optic cable. All CWDM cards are ITU-T G.694.2 compliant, passive (no electrical power required), and perform as both an optical multiplexer and optical de-multiplexer, allowing for bidirectional communication. They are form factor compatible with the 907 products and can be added to an existing stack, providing an upgrade path for additional functionality.
A 2-channel with a 1310/1550 nm bypass, 4-channel and 8-channel versions are available. The 2-channel version allows for simple expansion of an existing 1310/1550 nm Focal™ system.
