In this blog, ETU-LINK will talk about 10G DWDM Tunable module and its differences from ordinary DWDM optical module.

The wavelength of 10G conventional SFP+ DWDM optical module is fixed, while 10G SFP+ DWDM Tunable optical module can be configured to output different DWDM wavelengths. The wavelength tunable optical module has the characteristics of flexible selection of working wavelength, which has great practical value in optical fiber communication wavelength division multiplexing system, optical add drop multiplexer and optical cross connection, optical switching equipment, spare parts of light source and other applications. The wavelength tunable 10G SFP+ DWDM optical module is more expensive than 10G conventional SFP+ DWDM optical module, but it is also more flexible in use.

How to realize the efficient sharing and reuse of basic resources in the edge access layer is the network capability and competitiveness that operators need to build, so as to realize the rapid and efficient access of various services and move towards all-optical services. In all-optical network, Tunable DWDM laser has great application prospects in communication network, and has been widely used in backbone and metro core convergence network. Practice has proved that it can greatly simplify network construction and operation and maintenance.

The transmission distance of 10G DWDM SFP+ Tunable optical module of ETU-LINK is 80km and supports 50Hz and 100Hz. The 50Hz 10G DWDM SFP+ Tunable optical module can support 89 channels (C17-C61), and the channel range supported by 100HZ 10G DWDM SFP+ Tunable optical module is C17-C61.

From backbone network to metropolitan core and then to metropolitan edge access, wavelength tunable DWDM optical modules have a large number of waveguides and large capacity. There is no need to identify the wavelength of optical modules, reduce the type and quantity of spare parts, and greatly simplify network construction, operation and maintenance. At present, many operators at home and abroad have deployed wavelength division forward transmission solutions based on DWDM tunable optical modules.
