Under normal circumstances, SFP+ optical modules are classified according to actual applications. Common types include 10G SFP+, BiDi SFP+, CWDM SFP+, and DWDM SFP+.
1.10G SFP+ optical module
This type of optical module is an ordinary SFP+ optical module, and can also be regarded as an upgraded version of a 10G SFP optical module, which is currently the mainstream design on the market.
2.BiDi SFP+ optical module
This type of optical module uses wavelength division multiplexing technology, with a rate of 11.1G bps and low power consumption. It has two optical fiber jacks, which are generally used in pairs. When building a network in a data center, it can reduce the amount of optical fiber used and the construction cost.
3. CWDM SFP+ optical module
This kind of optical module adopts coarse wavelength division multiplexing technology, and is often used in conjunction with single-mode optical fiber, which can save optical fiber resources, and is more flexible and reliable in networking, and has low power consumption.
4.DWDM SFP+ optical module
This kind of optical module adopts dense wavelength division multiplexing technology, which is mostly used in long-distance data transmission, with a transmission distance of up to 80km, and has the characteristics of high speed, large capacity, and strong scalability.
