SFP+ high-speed cable, SFP+ electrical interface module and SFP+ optical module transmission rate is 10G, encapsulated SFP+, is used for high-speed data transmission solutions, they have different characteristics and advantages. In the actual application, we need to choose the appropriate transmission method according to their own needs and application scenarios. This article will be from the connection mode, transmission distance, features and advantages, the use of four aspects of the scene, the three transmission modes for a detailed comparison of the description, to help users better understand and choose the appropriate transmission mode.

First, the difference between the connection method

SFP + high-speed cable connection method:

SFP + high-speed cable is a high-speed data transmission cable, you can connect the device through its own SFP + module on both ends.

10G SFP+ electrical port module connection method:

The 10G SFP+ electrical port module is a hot-swappable optical-to-electrical module, which realizes the conversion of optical and RJ45 interfaces by inserting it into the SFP+ slot of the switch. The module connects the devices at both ends through the network cable.

SFP+ optical module connection mode:

SFP+ optical module is a kind of hot-swappable optical module, which realizes the connection between optical fibers by inserting it into the SFP+ slot of the switch, and it connects to the target device through optical fiber.

The transmission distance of SFP+ optical module is the farthest, which can reach 120km, while the transmission distance of SFP+ high-speed cable is the shortest, and the general transmission distance is not more than 7 m. Therefore, when choosing, you need to choose the suitable product according to the actual transmission distance requirements.

Second, the transmission distance is different

SFP+ high-speed cable, 10G SFP+ electrical interface module and SFP+ optical module are all devices used for 10G Ethernet transmission, and they also differ in transmission distance.

The transmission distance of SFP+ passive high-speed cables is the length of the self-contained cable, which is usually no more than 7 meters.

The transmission distance of 10G SFP+ electrical interface module is usually 30m.

The transmission distance of SFP+ optical modules is 300m to 120km.

From the above data, it can be seen that the transmission distance of SFP+ optical module is the farthest, which can reach 120km, while the transmission distance of SFP+ high-speed cable is the shortest, which is usually no more than 7 m. Therefore, when choosing, it is necessary to choose the suitable product according to the actual transmission distance requirements.

Third, the characteristics and advantages

SFP+ high-speed cable is a kind of electrical signal transmission equipment, does not have the photoelectric conversion function, can support the transmission speed of 10Gbps. It has the advantages of high flexibility, good compatibility, strong signal anti-interference, easy installation, and lower cost.

10G SFP+ electrical port module is a kind of optical-to-electrical module for connecting Ethernet devices, supporting 10Gbps transmission speed. It supports the use of standard RJ-45 cables for connecting devices, which reduces costs and also provides fast, reliable, and stable data transmission capabilities.

SFP + optical module is a photoelectric conversion module for connecting network equipment, it is connected by optical fiber, the main advantage is fast transmission speed, strong signal anti-interference, transmission distance is farther.

Fourth, the difference between the use of the scene

SFP+ high-speed cable is suitable for short-distance wiring between network devices (≤ 7m), such as servers, switches, routers, etc..

10G SFP+ electrical port module is suitable for occasions requiring high-speed data transmission and shorter distance transmission (≤ 30m), such as connecting servers or data transmission via WAN.

SFP+ optical modules are suitable for long-distance fiber optic transmission scenarios, such as data centers, MANs, telecom networks, etc.

In summary, SFP+ high-speed cables, 10G SFP+ electrical port modules and SFP+ optical modules have obvious differences and discrepancies in connection methods, transmission distances, usage scenarios and other aspects. When choosing a transmission method, you need to fully consider your needs and application scenarios in order to choose the appropriate transmission method.
