Product Description
Coarse Wavelength Division Multiplexing
(CWDM) is an excellent choice for increasing bandwidthz capacity while keeping
costs down. The 6com splice/pigtailed ABS module family, based on standard Thin
Film Filter (TFF) technology with a proprietary packaging, offers you smallest
component dimensions combined with an outstanding performance and reliability.
