Differences between SFP and SFP +
2017-09-24
Many people do not know the difference between sfp and sfp +, so sometimes bring unnecessary trouble. 10G module has experienced from the 300Pin, XENPAK, X2, XFP development, and ultimately achieved the same size and SFP transmission 10G signal, which is SFP +. SFP by virtue of its small and low cost and other advantages to meet the equipment on the high demand for optical modules, from the 2002 standard implementation, to 2010 has replaced XFP 10G market mainstream.
SFP + optical module advantages:
1, SFP + has a more compact form factor (same size as SFP) than X2 and XFP packages;
2, and the same type of XFP, X2, XENPAK direct connection;
3, the cost is lower than XFP, X2, XENPAK products.
Differences between SFP + and SFP:
1, SFP and SFP + appearance of the same size;
2, SFP protocol specification: IEEE802.3, SFF-8472;
Differences between SFP + and XFP:
1, SFP + and XFP are 10G fiber modules, and with other types of 10G modules can communicate with each other;
2, SFP + smaller than the XFP appearance size;
3, because the smaller size of the SFP + signal modulation function, serial / deserializer, MAC, clock and data recovery (CDR), and electronic dispersion compensation (EDC) function from the module to the motherboard;
4, XFP compliance protocol: XFP MSA protocol;
5, SFP + compliant protocols: IEEE 802.3ae, SFF-8431, SFF-8432;
6, SFP + is more mainstream design.
3, SFP + protocol specification: IEEE 802.3ae, SFF-8431, SFF-8432.
The available optical SFP modules are generally classified into the following categories: 850F nm / 550 m distance MMF (SX), 1310 nm wavelength / 10 km distance SMF (LX), 1550 nm wavelength / 40 km distance XD, 80 km distance ZX, 120 km away from EX or EZX, and DWDM.
About X2 interface:
X2 is a standardized form of 10.3 Gb / s for 10.5 Gb / s data transfer rate of 10 Gb / s fiber optic fiber transponder It is a specific protocol:
10G Ethernet or 10G Fiber Channel version. X2 transponders, used in data communications fiber links (telecom), they are smaller than the older generation XENPAK forwarding. The electrical interface of the motherboard is also standardized, known as XAUI (4 × 3.125 Gb / s). WZT manufacturing X2 300M, X210 km, X220 km, X240 km, X280 km optical module. All modules support the functions of Digital Optical Monitoring (DOM).
DWDM X2: Dense Wavelength Division Multiplexing (DWDM) X2 pluggable module allows enterprise companies and service providers to provide scalability and easy deployment of 10 Gigabit Ethernet services on their networks. Both DWDM X2 ER 40km and DWDM X2 ZR 80 km can be used for DWDM 10G Ethernet applications.

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.
