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 and so on. The most importantly, we this 8+1CH CWDM Mux/Demux Module can up to industrial Grade which can be operated under -40~+85℃.
