What Is The Difference: SFP vs SFP+
2017-06-17
As we know, a SFP module just looks the same as the SFP+ module. And most switches can both support SFP module and SFP+ module. So, do these two modules really refer to the same one? What’s the difference between them?
SFP Definition
SFP stands for Small Form-factor Pluggable. It is a hot-pluggable transceiver that plugs into the SFP port of a network switch and supports SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. SFP specifications are based on IEEE802.3 and SFF-8472. They are capable of supporting speeds up to 4.25 Gbps. Due to its smaller size, SFP replaces the formerly common gigabit interface converter (GBIC). Therefore SFP is also called Mini-GBIC. By choosing different SFP module, the same electrical port on the switch can connect to different fiber types (multimode or single-mode) and different wavelengths.
SFP+ Definition
Since SFP supports only up to 4.25 Gbps, SFP+ that supports data rates up to 16 Gbps was later introduced. In fact, SFP+ is an enhanced version of the SFP. The SFP+ specifications are based on SFF-8431. In today’s most applications, SFP+ module usually supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. In comparison to earlier 10 Gigabit Ethernet XENPAK or XFP modules, SFP+ module is smaller and becomes the most popular 10 Gigabit Ethernet module in the market.
SFP vs SFP+
Review the SFP and SFP+ definition mentioned above, we can know that the main difference between SFP and SFP+ is the data rate. And due to different data rate, the applications and transmission distance is also different.
Usually, SFP module plugs into SFP port of the switch and SFP+ module plugs into SFP+ port of the switch. But, sometimes SFP module can also be plugged into SFP+ port. Which SFP or SFP+ module should you choose all depends on your switch types. Fiberland is a reliable SFP transceiver module manufactures, all SFP module and SFP+ module types are available in Fiberland. Besides, SFP+ cable is also provided. What’s more, the price of SFP module and SFP+ module is lower than many other manufactures. SFP test is strict in Fiberland. Matching fiber patch cable is also available.

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.
