The Difference Between Tunable DWDM Transceiver and Fixed-wavelength DWDM Transceiver

Publish Time: 2021-09-22 Views: 96

The wavelength of 10G SFP+ DWDM optical transceiver is fixed, while 10G SFP+ DWDM tunable optical transceiver can be configured to output different DWDM wavelengths. The wavelength tunable optical transceivers have the characteristics of flexible selection of working wavelengths, which are used in optical fiber communication wavelength division multiplexing. The system, optical add/drop multiplexer and optical cross-connect, optical switching equipment, light source spare parts and other applications have great practical value. Wavelength tunable 10G SFP+ DWDM optical transceivers are more expensive than 10G SFP+ DWDM optical modules, but they are also more flexible in use.


How to achieve efficient sharing and multiplexing of basic resources at the edge access layer is a network capability and competitiveness that operators need to build to achieve fast and efficient access to various services and move toward all-optical services. In all-optical networks, tunable DWDM lasers have huge application prospects in communication networks, and have been widely used in backbone and metropolitan core convergence networks. Practice has proved that network construction and operation and maintenance can be greatly simplified.


The Skyward Telecom 10G DWDM SFP+ tunable optical transceiver has a transmission distance of 80KM and supports 50HZ and 100HZ. The 50HZ 10G DWDM SFP+ tunable optical transceiver can support 89 channels (C17-C61), and the 100HZ 10G DWDM SFP+ Tunable is adjustable. The channel range supported by the optical transceiver is C17-C61.
