Low Insertion Loss 4CH WDM Multiplexer Devices Fiber Optic Passive
High Channel Isolation with water proof for FITL Use
Description
The 4 channels CWDM passive MUX and DEMUX modules deliver the benefits of a Coarse Wave Division Multiplexer in a fully passive solution .With matching MUX DEMUX units placed at each end of an optical
link, up to 4 channels can be combined and transmitted over a
single-mode fiber trunk. It covers all channels from 1270nm to 1610nm in 20nm increments
4 channels plastic insert type structure passive CWDM MUX DEMUX, compact and lightweight, and strong environmental adaptability.
Can be placed independently (using a binding band to fix), also like the splitter, placed in the corridor of the fiber box, when the central office needs more than one centralized placement,
it can also be inserted into the 16-slot 3U passive chassis.
4 channels plastic insert type structure passive CWDM MUX DEMUX, waterproof, dustproof, and resistant to high and low temperature,
high reliability, no power supply and other advantages.
