1/2/4 Channels CWDM OADM, Single Fiber, East and West, Optional Connectors and Housing

CWDM Optical Add/Drop multiplexer (OADM) is a passive optical device used in WDM networks for adding and dropping one/multiple CWDM channels into one or two fibers, while letting the rest of the wavelengths bypass to the needed destination. Through the use of CWDM technology, individual channels can be optically extracted from a fiber pair while allowing pass-through traffic to continue unobstructed through the bus or ring.

CWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations supporting up to four wavelengths. Each CWDM OADM uses wavelengths that fall within the ITU-T G.694.2 CWDM grid standard from 1270nm to 1610nm with 20nm spacing.

FS CWDM OADM are modular, scalable and are perfectly suited to 10/1G Ethernet, 16/8/4/2/1G FC, SDH/SONET, Video, CATV, FTTx applications.

Choosing of the Appropriate Wavelengths

A water peak in optical fiber attenuation in dB/km occurs at a narrow range of wavelengths within the telecommunication spectrum 1260 – 1625nm. For G.652 and G.694.2 optical fiber, the water peak occurs at 1383 ± 3nm, which means avoiding 1390nm and 1410nm wavelengths because of the higher attenuation.

CWDM Add & Drop  Choosing of the Appropriate Wavelengths

Line Type

Dual fiber and single fiber, supporting bidirectional transmission

CWDM Add & Drop  Line Type

Transmission Direction
West or East Module

Single-sided transmission. It drops or adds one wavelength-specific channel from the network fiber and allows the remaining channels to pass straight through to other nodes along the network.

CWDM Add & Drop  West or East Module
CWDM Add & Drop West and East Module
West and East Module

Dual-sided transmission. It drops an individual channel from the network fiber, and it also provides the ability to add that same channel back onto the network fiber.


Various connectors are available - LC/SC/FC/ST, UPC/APC polish

Questions & Answers
  • Q:

    What else custom services can you provide about CWDM OADM? By Amit on 08/01/2017


    Any wavelength, any connector, any type of housing (FMU/FUD/1U rack/ABS module/OADM components) and special ports, like 1310nm/1550nm/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 on 08/01/2017

  • Q:

    What do you need to consider when customize the CWDM OADM into a ABS module? By Gies on 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 on 07/25/2017

  • Q:

    How many channels are available for CWDM OADM? By Bolin on 07/19/2017


    Following the standard ITU-T G694.2, CWDM OADM modules allow up to 18 individual wavelengths/channels separated by 20nm spacing from 1270nm to 1610nm. Any wavelength or wavelengths combination can be customized upon request. By FS on 07/19/2017
