1/2/4/8 Channels DWDM OADM, Single Fibre, East or West, Optional Connectors and Housing

DWDM Optical Add Drop Multiplexer (OADM) is a passive optical device used in WDM networks for adding and dropping one/multiple 100GHz DWDM channels in the C-band into one or two fibres, while letting the rest of the wavelengths bypass to the needed destination. Using the DWDM technology can effectively add WDM capability to their existing and new networks, and extend the optical signals transmission distance.

DWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations, which are perfectly suited for 10/1G Ethernet, 16/8/4/2/1G FC, SDH/SONET, Video, CATV, FTTx applications. With matching MUX/DEMUX units placed at each end of an optical link, multiple data channels can be combined and transmitted over a single-mode fibre trunk. The passive DWDM OADM modules can add or drop up to 4 data channels at any point along the trunk.

DWDM ITU Grid in C-Band

In compliance with ITU-T G.694.1, the most commonly used grid is the 100GHz grid with spacing of 0.8nm per channel, which supports up to 40 wavelengths from C21-C60.

DWDM Add & Drop DWDM ITU Grid in C-Band

Line Type

Dual fiber and single fiber, supporting bidirectional transmission

DWDM 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.

DWDM Add & Drop  West or East Module
DWDM 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

The Transmission Between DWDM MUX with 1310 Special Port and OADM

1.If OADM also has 1310 special port, the 1310 signal can be transmitted by adding and dropping at each site, as shown in the figure, ① and ② is a group of signals, ③ and ④ is a group, ⑤ and ⑥ is a group.
2.If OAMD does not carry 1310 special port, because the working wavelength of OADM limits 1520nm-1570nm, the 1310 signal cannot be transmitted directly, unless customize the OADM for a particular wavelength.
