Frequently Asked Questions

SFP Transceivers and Cables

Can I use an SFP module on RJ45 Ethernet port?

No, SFP modules are designed for SFP-compatible ports, which are specifically built to accept the module and provide electrical connections. RJ45 Ethernet ports do not support the physical or electrical interface required for SFP modules.

Is SFP backward compatible with SFP+ ports?

Yes. Standard 1G SFP modules can operate in SFP+ ports, but they will run at 1G speeds only. SFP+ ports can automatically negotiate down to support SFP modules.

How can I ensure SFP compatibility with my switch or router?

Check the device's specification sheet or compatibility list published by the manufacturer. Alternatively, choose multi-vendor compatible SFP modules, which are coded to work across a wide range of brands like Cisco, HP, Juniper, and more.

What are the main differences between SFP and SFP+ modules?

The primary difference is speed: SFP supports up to 1 Gbps, while SFP+ supports up to 10 Gbps. SFP+ also features enhanced signal integrity and lower latency, making it the preferred choice for high-speed data center and enterprise backbone networks.

What are the common types of 1G SFP modules, and how do they differ?

SX: Short-distance multimode fiber (MMF), typically supporting a few hundred meters.
LX/LH: Long-distance single-mode fiber (SMF), typically supporting several kilometers to over ten kilometers.
EX/ZX: Extended-distance single-mode fiber (SMF), supporting even longer distances.
TX/T: 1000BASE-T copper SFP, using Cat5e/Cat6 cabling with a typical transmission distance of up to 100 meters.
The main differences lie in the supported transmission media (fiber type or copper cable) and the transmission distance.
