10GBase Ethernet Introduction

Choosing Between 10GBASE-T and SFP+

Huihongfiber’s Copper SFPs currently have two types: Copper SFPs and SFP+ Copper SFPs.

Copper SFP: According to different transmission rates, it can also be divided into 100M Copper SFP, Gigabit Copper SFP and self-adaptive Copper SFP. The gigabit optical module integrated on the CMOS chip can be used for high-speed Ethernet and Gigabit Ethernet. Different from other Copper SFPs, this Copper SFP is more innovative in speed and can meet various needs.

SFP+ Copper SFP: also known as 10 Gigabit Copper SFP, 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+ Copper SFP is the first 10G optical module that transmits through a network cable. It can be used in the SFP+ port of a switch or a network card to realize the connection with a network device with an RJ45 interface.

The maximum transmission distance of the 10GBASE-T SFP+ RJ45 Copper SFP on the Cat6a/7 network cable is 100 meters. Compared with the embedded 10GBASE-T RJ45 port, each port saves at least 0.5W of power. It is the first module that can provide 10Gb/s rate through Ethernet copper cable (network cable), and this module complies with SFF-8431 and SFF-8432 MSA standards. In addition, compared with 10GBASE-T fixed port electrical port switches, 10GBASE-T SFP+ Copper SFPs can work on existing SFP+ ports, providing greater flexibility for their applications.

The typical features of 10GBASE-T SFP+ Copper SFP are as follows:
Dimensions: Interoperable with any rack system with SFP+ ports.
Performance: Using the PHY standard, data can be transmitted error-free over copper cables using block encoding.
Innovation: Support manageable hot-plug function.
Auto-negotiated backward compatibility: It can be compatible with previous generation 10/100/1000BASE-T networks for seamless migration to 10Gb Ethernet.

10GBASE-T SFP+ Copper SFP, 10G DAC high-speed cable and 10G SFP+ optical module are the main solutions for 10G Ethernet. However, with cheap SFP+ DAC high-speed cables and SFP+ optical modules that can be used for 10G Ethernet, why do we need 10Gb SFP+ Copper SFPs?
First of all, the RJ45 ports on the switch are used to connect to the network cable, but the few RJ45 ports on the switch are not enough to meet the needs of copper cabling in the data center. In this case, the 10GBASE-T SFP+ Copper SFP can convert the optical port into an electrical port to meet the shortage of RJ45 ports on the switch.
Secondly, in data centers and enterprise networks, the length of most links is between 10m and 100m, and the 10GBASE-T SFP+ Copper SFP can provide 10Gb/s data transmission within a distance of 100 meters, which is very good It makes up for the limitation that the SFP+ DAC high-speed cable can only transmit 10 meters.
Finally, 10GBASE-T Copper SFPs can be backward compatible with 10/100/1000BASE-T optical modules, thus saving a lot of budget for data center networks. When connecting the 10G optical module to the copper cable network, the 10GBASE-T Copper SFP can be directly added to the copper cable network, while the 10G SFP+ optical module needs to be used together with the fiber optic transceiver to realize this application, so 10GBASE-T T SFP+ copper module has advantages over SFP+ optical module solution, because the cost of copper cable infrastructure is much lower than that of optical fiber.

Huihong Technologies makes both 10Gbase-T copper SFP+ and 10/100/1000Base copper SFP, factory price, super quality and fast delivery.
