DWDMDense Wavelength Division Multiplexingrefers to a fiber data transmission technology. This technique uses the wavelength of the laser to transmit data in the optical fiber by parallel transmission of bit bits or string  line transmission. And the DWDM module is the optical module that combines this technology, and it has 40 common channels to choose.

It is widely used in different fields of communication networks, including long-distance backbone network, metropolitan area network (MAN), resident access network and local area network (LAN), etc. Today we will share and learn the knowledge of DWDM modules.


What is DWDM optical module?

The DWDM module belongs to the wavelength division multiplexing technology, using different wavelengths to multiplex multiple optical signals into an optical fiber. The operation doesn’t need any power consumption. The channel interval of DWDM module is small, requires additional wavelength control devices. The rate is up to 10Gbps, and the transmission distance can reach 100km.



What are the classification of DWDM optical modules?

The DWDM modules on the market usually have: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2 and DWDM XENPAK optical transceiver.


What are the advantages of DWDM optical module?

The DWDM optical module supports pluggable and tunable, 40 common channels are available for selection, this greatly reduces the demand for independent pluggable modules.

According to different requirements, DWDM module has different channel intervals such as 0.4nm, 0.8nm, and 1.6nm. It can support long distance transmission of 100km, which can be used as an effective solution to solve line bandwidth expansion.


What are the applications of the DWDM optical module?

Enlarge DWDM network fiber channel

Ring topology, fixed and reconfigurable OADM

Fast Ethernet, Gigabit Ethernet

Other optical fiber transmission systems


Router / server interface, etc.



ETU-Link can provide DWDM modules with different packaging types, transmission distance and transmission rate. It also has the characteristics of stable performance and strong compatibility.
