Product Description

Rack Mount 4CH 8CH 16CH CWDM DWDM for WDM Optical Network
Product Description
Lightwit Dense wavelength division multiplexer (DWDM 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.
For DWDM Mux/Demux, besides the common filter type DWDM, Lightwit also offers a whole range of Thermal/Athermal AWG products to meet the need for dense channel DWDM products, including 50GHz, 100GHz and 200GHz AWG. Channel number from Thermal/Athermal 200G 16 channel AWG up to Thermal/Athermal 50G 96 channel AWG packed in a single package.
