Description
-
Swedish Telecom Opto Coarse wavelength division multiplexer (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.
Configuration example:
8 Channel Double Fiber CWDM Mux/Demux,
1471–1611nm , IL below 1.5 dB, with CCWDM filters,19″1U Rack
