Product Description

Passive Optic Fiber 4+1 Channel CWDM Mux Demux

Gvdlink Solution Passive Optic Fiber Multiplexer Module 4+1 Channel CWDM Mux Equipment



   Modular 4 Channel CWDM Mux/demux is a flexible and low-cost solution that enables the expansion of existing fiber capacity. Coupled with highly reliable passive optics certified for environmentally hardened applications, the CWDM MUX/DEMUX solution lets operators make full use of available fiber bandwidth in local loop and enterprise architectures. Our CWDM MUX/DEMUX modules split up to 18 channels (20 nm spaced) to a single fiber. The standard packages are ABS Plastic Box, 19" Rack Mount Chassis and LGX Metal Box. No matter what kind of connectors (such as FC, ST, SC, LC, etc.) are all available, and we can also mix connectors on one device.


  • Low Insertion Loss
  • High Isolation and low PDL
  • Compact Design

  • Good Channel-to-channel Uniformity
  • Wide Operating Wavelength: 1260nm~1620nm or 1460nm~1620nm

  • Wide Operating Temperature: -40℃~85℃
  • High Reliability and Stability with RoHS compliant and lead free
