Product Description

optical add-drop multiplexer 4ch cwdm oadm module

Product Description

ptical Add-Drop Multiplexer (OADM) is used for multiplexing and routing different channels of fiber into or out of a single fiber. The CWDM OADM is designed to optically add/drop one or multiple CWDM channels into one or two fibers.
Lightwit Photonics provides a series of CWDM OADM modules with as more as 18 channels (20nm spaced) in simplex or duplex configurations. All the CWDM modules are available with three types of packaging: ABS Pigtailed Box, Rack Chassis and LGX Cassette.

 

Features
Dual fiber or Single fiber for East and West traffic
ABS box, LGX or 1U Rack Mount
ITU-T G.657A1 CWDM standard
Monitor port is optional

Applications
CWDM system
CATV system
Telecommunication network system
Metro/Access networks
