10G SFP+ optical module and 10G XFP optical module are optical modules that can transmit and receive 10G data signals per second, and can convert light to electricity and electricity to light, while SFP and XFP represent their packaging forms. 10G optical modules have XENPAK, X2 and so on, but the mainstream of 10G optical modules is still XFP optical module and SFP+ optical module. Next, Yi Tian Optical Communication (etulink.com) will answer in detail whether the interconnection of 10G SFP+ optical module and XFP optical module can communicate.

The SFP+ optical module and the XFP optical module are interconnected between the two switches, and the OM3 optical jumper is used to form a 10G path. As the optical transceiver module for 10G data transmission, the 10G connection between the SFP+ optical module and the XFP optical module is feasible. If the optical modules on both sides of the fiber link are 10 gigabytes, if there are SFP+ modules on one side and XFP modules on the other, XFP optical modules and SFP+ optical modules are compatible at the same wavelength and signal rate (the transmission distance is the same, the wavelength is the same, for example, 10G dual fiber optical modules are 300m, 10KM, 20KM, 40km or 80km, wavelength 1310nm 1550nm, etc.), you can directly connect the communication. More specifically, the XFP optical module and the SFP+ optical module actually have the same specification standard. But it is worth noting that the SFP+ optical module and the XFP optical module are not interchangeable.

The SFP+ optical module is a 10G hot-swappable module that is independent of the optical transceiver of the communication protocol. It usually transmits light at the wavelength of 850nm, 1310nm or 1550nm. It is used in 10G bps SONET/SDH, fibre Channel, gigabit Ethernet,10 gigabit Ethernet and other applications, including DWDM links. XFP includes a digital diagnostic module similar to SFF-8472, but has been extended to provide powerful diagnostic tools. The small size, low cost and multi-application characteristics of SFP+ optical module are more suitable for the needs of high-density data center. SFP+ 10-gigabit optical module meets the needs of high-density optical module with its advantages of miniaturization and low cost. Now it has replaced 10G XFP optical module to become the mainstream of 10G market.

XFP optical module is a kind of serial-serial optical transceiver which is hot-swappable and occupies a small circuit area. It consists of three parts: transmitting, receiving, memory and diagnosis. The transmitting part includes TOSA and LD driving circuit, while the receiving part is composed of ROSA and main amplifier. Flash/EE unit is mainly used to store information such as module type, interface form, transmission characteristics, product type and manufacturing date. The XFP optical module with digital diagnosis and monitoring function not only stores the above information, but also has a microcontroller and a series of digital-analog and analog-to-digital conversion interfaces, which are used to monitor the five parameters of the optical module in real time, namely, temperature, voltage, laser bias current, output optical power and input optical power. It can support SONET OC-192, 10Gbps Ethernet, 10Gbps fibre Channel and G709 links, mostly using LC interface. XFP's Multi-Source Protocol (MSA) directly uses the XFI interface specification to define the power interface, which fully meets the limitations of the SDH optical transmission network. Compared with 1X9 and SFP module, XFP has higher transmission rate and transmission capacity, which expands the application scope of Ethernet to metropolitan area network and wide area network.

XFP optical modules are used in a wide range of applications, including 10G bps SONET/SDH, fibre Channel, 10G Ethernet, SONET/OC-192, SDH/STM-64HE and other applications including DWDM links.

Nowadays, in order to achieve a modern data center with large scale, high bandwidth, high flexibility, high efficiency and high interconnection, the data center ecosystem is experiencing unprecedented development and innovation in order to further promote optical interconnection technology. With the maturity of 10G network technology, most users have used 10G/ 40G optical module to build their own network transmission system.
