Differences and applications of SFP+/XFP/X2 and XENPAK in 10G modules
2019-09-11
If we need to understand the differences and applications of SFP+, XFP, X2, and XENPAK in 10G modules, we need to know what the 10G SFP+ and 10G XFP optical modules are.
The 10G SFP+ optical module and the 10G XFP optical module are optical modules that can transmit and receive 10G data signals and can convert and convert light into electricity. According to the package form, it is mainly divided into SFP, XFP, XENPAK, X2, XFF, etc. However, the current mainstream of 10G optical modules are either XFP optical modules and SFP+ optical modules.
What are the differences between these different packages?
The 10G SFP+ optical module is an upgraded version of the SFP optical module and is based on the SFP package. The 10G XFP optical module is based on the XFP package standard.
1. The appearance of the size of the optical module
The 10G SFP+ optical module has a smaller external size than the 10G XFP optical module, so the 10G SFP+ optical module can meet the volume requirements of the high-density board for the optical module.
However, due to the large size of the 10G XFP optical module, its heat dissipation function is easier to dissipate than the 10G SFP.
2. Optical module dispersion compensation function (EDC)
The 10G SFP+ optical module has moved the signal modulation function, serializer/deserializer, MAC, clock and data recovery (CDR), and electronic dispersion compensation (EDC) functions from the module to the motherboard card. So 10G SFP+ has no EDC function.
However, the 10G XFP optical module also has this function. Therefore, when the switch router does not integrate the functions required by the 10G SFP+ optical module on the main board, it needs to be compensated by the 10G XFP optical module.。
3. The cost of the optical module
10G SFP+ optical modules are cheaper than 10G XFP, XENPAK, and X2 optical modules, and can interoperate with other types of 10G optical modules.In the 10G communication field, the SFP+ can be directly connected using a high-speed cable (DAC) with two 10G SFP+ optical module ports, eliminating the need to purchase two 10G SFP+ optical modules separately.However, 10G XFP, XENPAK, and X2 do not have this mode.
4. The port of the switch
The 10G SFP+ port on the switch can accept SFP optical modules, while the 10G XFP ports can only accept 10G XFP optical modules. The XENPAK and X2 optical modules can only accept fixed ports.
According to the above differences, the small size, low cost and multi-application characteristics of SFP+ optical modules are more suitable for high-density data centers.
These favorable factors also make SFP+ the most mainstream module at present, which is already small and hot swappable. Nowadays, 10G XFP optical modules have been replaced as the mainstream of the 10G market. All of the optical modules mentioned above, fiberland Ltd. are all on sale.

012019-10With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

012019-101. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

012019-10AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.
