The wavelength of the 10G conventional SFP+ DWDM optical module is fixed, while the 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 the working wavelength. In the optical fiber communication wavelength division multiplexing system, Optical add/drop multiplexers and optical cross-connects, optical switching equipment, light source spare parts and other applications have great practical value. Wavelength tunable 10G SFP+ DWDM optical modules are more expensive than conventional 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 great application prospects in communication networks, and have been widely used in backbone and metro core convergence networks. Practice has proved that network construction and operation and maintenance can be greatly simplified.
The 10G DWDM SFP+ Tunable tunable optical module has a transmission distance of 80KM and supports 50HZ and 100HZ. The 50HZ 10G DWDM SFP+ Tunable optical module can support 89 channels (C17-C61), and the 100HZ 10G DWDM SFP+ Tunable optical module supports the channel range It is C17-C61.
From backbone network to metropolitan area core, to metropolitan area edge access, wavelength tunable DWDM optical modules, large number of waveguides, large capacity, no need to identify the wavelength of optical modules, reduce the types and quantity of spare parts, greatly simplify network construction and operation dimension. At present, many operators at home and abroad have deployed WDM fronthaul solutions based on DWDM tunable optical modules.
