Product Highlights

Cost-Effective and Scalability Fiber Multiplier--CWDM Network

CWDM is a standardized WDM technology that use multiple wavelengths to transport information over a single/dual fiber. This enable CWDM becoming a very attractive option in metro and access networks that require additional bandwidth.

Cost-Effective and Scalability Fiber Multiplier--CWDM Network

Mux/Demux 4 Channels Single Fiber in a Pair
  • Low-profile 1U half 19'' rack plug-in module design
  • Expansion port cascades one more Mux to expand an existing CWDM system
  • Completely passive, no power & no cooling required

Optical Wavelength Bands Extends CWDM Reach

The 1470-1610nm channels avoid the water peak region of E-band. The S-, C- and L-bands inhabit the natural region for low optical losses in glass fiber, which can boost optical signal and extend the transmission distance.

Optical Wavelength Bands Extends CWDM Reach

Expansion Port - for Future Bandwidth Increasing

Expansion port makes it possible to increase the network capacity by connecting it to the line port of another CWDM MUX/DEMUX supporting different wavelengths, without the need of installing or leasing additional fibers .

Expansion Port - for Future Bandwidth Increasing

Remarkable Concentration and Manageability

Mux/Demux can increase your network capacity combined with FS Multiservice Transport (such as EDFA, DCM, OEO and so on), which can improve the manageability and interconnectivity of WDM Netwrok.

Remarkable Concentration and Manageability


• CWDM is used to increase the bandwidth of an optical fiber by multiplexing several wavelengths (or colors) onto it.
• When it is not in use, please capped with a clean dust cap, and keep adapter ports and fiber connectors clean.
• Attached sticker describes the specifications of MUX, which improves deployment flexibility for your WDM system.
• FS.COM always focus on design, R&D, innovation to provide you optimal products. Welcome to contact or

Questions & Answers About This Product

  • QDoes the fiber type affect the wavelength choosing?
    A Traditional G.652 optical fiber has obvious water peak in the general regions of 1380nm, which means avoiding 1390nm-1430nm CWDM channels, like items #42830. But Zero Water Peak Fiber (ZWPF) ITU-G. 652.D and ITU-G G.657.A1 resolves water peak issues.

  • QHow to deploy a hybrid CWDM/DWDM network over one pair of fiber?
    A This could be achieved by connecting the 1530nm or 1550nm CWDM channel to the line port of DWDM Mux Demux. CWDM 1530nm matches to narrowband C52-C61 of DWDM, CWDM 1550nm matches to narrowband C27-C42 of DWDM. Like items #61646 & #26569.

  • QIf the 40G QSFP+ LR4 transceiver could be connected to the 1310nm special port?
    A Yes, connect them by using a piece of fiber optic cable with the same connector type, like LC/UPC duplex. Meanwhile, if using the 1310nm special port, wavelength 1270nm, 1290nm, 1310nm, 1330nm and 1350nm could not be used on the CWDM Mux Demux.
