4ch Dual Fiber DWDM Add+Drop Multiplexers in splice/pigtailed ABS module, 100GHz ITU grid

DWDM/AD modules are Dense Wave Division Multiplexing (DWDM) Optical Add/Drop Multiplexers (OADM). The DWDM/AD modules add (multiplex) and drop (demultiplex) selected channels, or wavelengths, on both directions (east and west) or one direction (east or west) of a DWDM common fiber link. The technology enables intelligent planning and flexible provisioning of optical services while simplifying the deployment and maintenance of optical networks. Access points can be added to linear, bus, and ring networks, where the east and west ring design provides redundant protected architecture.

DWDM passive OADM modules are protocol-transparent and invisible to both the network and the users, each DWDM passive OADM uses wavelengths that fall within the ITU-T G.694.2 DWDM grid standard from C17 to C61(1563.86~1528.77nm) with 0.8 nm spacing.

  • Question:

    What else custom services can you provide about DWDM OADM? By Celso Answer this question

    By Celso 08/01/2017

    Any wavelength, any connector, any type of housing (FMU/FUD/1U rack/ABS module/OADM components) and special ports like 1310nm/Monitor port( 1% ratio as default, 2%, 3%, 5%, etc, available on request) can be customized. What's more, FS OADM can be customized to industrial temperature -40~85℃ to meet the requirement of outdoor applications. By FS.COM

  • Question:

    What do you need to consider when customize the DWDM OADM into a ABS module? By David Lash Answer this question

    By David Lash 07/25/2017

    Fiber diameter ( 2.0mm, 0.9mm, 3.0mm ), pigtail length ( 0.25~2m, no extra charge ), with/without connectors, and ABS size (141*115*18mm, 120*80*18mm, 100*80*10mm) need to be considered. By FS.COM

  • Question:

    How many channels are available for DWDM OADM? By Timandra Answer this question

    By Timandra 07/16/2017

    Following the ITU-T G.694.1 Grid, FS DWDM OADM supports two standard channel options, including 48 channels on 100 GHz ITU grid or 96 channels on 50 GHz ITU grid. No more than 48/96 DWDM channels, any wavelength or wavelengths combination can be customized upon request. But 50 GHz OADM is more expensive than 100 GHz, low channel numbers are not suggested.
