What is an electrical port module?

Electrical port module is also called the optical port to electrical port module. It is a module that supports hot plugging and is packaged in SFP. In addition, since the transmission distance of the electrical interface module is 10-30m or 80-100m, the electrical interface module is mainly used for short-distance data transmission.

Why choose an electrical port module?

At present, the link distance between devices in most data centers is between 10 meters and 100 meters. The use of 10 Gigabit electrical port optical modules can make up for the lack of SFP+ high-speed cable transmission distance. Secondly, the electrical port optical module adopts RJ45 interface and is used together with super Cat 6 or Cat 7 network cables, and the cost of copper cabling is lower than that of optical cabling.


Features and advantages of electrical port modules

The electrical port module complies with SFP MSA and IEEE Std 802.3-2002 standards, and features low power consumption, high performance, and compact design. In addition, the electrical port module can not only make up for the short distance of SFP+ high-speed cable transmission distance, but also directly use the existing copper cabling system to achieve 10G data transmission, and the use of SFP+ optical modules requires optical cables for wiring. Increase the cost of network deployment.


Classification of electrical port modules:

Electrical interface modules can be divided into SFP electrical interface modules, SFP+ electrical interface modules, and GBIC electrical interface modules according to different package types.


1. SFP electrical port module: According to the different transmission rate, it can be divided into 100M electrical port module, Gigabit electrical port module, adaptive electrical port module, and adaptive electrical port module.

2. SFP+ electrical port module: also known as 10 Gigabit electrical port module, the rate is 10G, designed for high-speed communication links, mainly used in 10 Gigabit Ethernet, and its power consumption is also very small. In addition, the SFP+ electrical interface module is the first 10G optical module to transmit through a network cable. It can be used in the SFP+ port of a switch or network card to achieve connection with network equipment with an RJ45 interface;

3. GBIC electrical interface module: It is an electrical interface module with the package type of GBIC. The transmission rate can reach 1000Mbps and the maximum transmission distance can reach 100m.


Electrical interface modules can be divided into 10G SFP+, 100Base SFP, and adaptive electrical interface modules according to different speeds. The following are the introduction of these three types of electrical interface modules:


100Base SFP electrical port module can be used when the network port of the device is insufficient, that is, the SFP optical port is converted into an RJ45 electrical port by using the SFP electrical port module. The 100Base SFP electrical interface module and the SFP optical module have the same electrical interface. The difference is that an external interface uses an electrical interface (that is, an RJ45 interface) and an optical interface.


10G SFP+ electrical interface module is also called 10G electrical interface module. Its speed is 10G and it is designed for high-speed communication links. It is mainly used in 10G Ethernet. The standards of 10G optical modules are IEEE 802.3ae and IEEE. 802.3ak and IEEE 802.3an. In terms of packaging, 10G optical modules include 10G SFP+ optical modules, BIDI SFP+ optical modules, CWDM SFP+ optical modules, DWDM SFP+ optical modules, 10G XFP optical modules, BIDI XFP optical modules, CWDM There are nine types of XFP optical module, DWDM XFP optical module and 10G X2 optical module.


And its power consumption is almost half of the power consumption of optical modules, so it is an excellent power optimization solution. In addition, the 10G SFP+ electrical port module is the first 10G optical module to transmit through a network cable. It can be used in the SFP+ port of a switch or network card to achieve connection with network equipment with an RJ45 interface.


10 Gigabit electrical port optical module has the characteristics of high performance and strong reliability. It is mainly used to achieve 10G Ethernet transmission in super Category 6 or Category 7 copper cabling systems, and the transmission distance can reach 30 meters. Compared with SFP+ high-speed cable, it can save power consumption of at least 0.5W, and its port can support both shielded twisted pair and unshielded twisted pair.


The self-adaptive electrical interface module is a Gigabit optical module capable of integrating three 10/100 /1000BASE rates into a CMOS chip. It can be used for high-speed Ethernet and Gigabit Ethernet. Unlike other electrical interface modules, This electrical port module is more innovative in terms of speed and can meet different application needs.
