1G SFP Transceiver Modules

SX (short wavelength) modules are for short-distance data transmission (up to 550 meters) over multi-mode fiber. LX (long wavelength) modules are used for long-distance links (up to 10 km or more) over single-mode fiber. The choice depends entirely on your network's cabling infrastructure and required reach.

Absolutely. Every module we sell undergoes a rigorous 5-step quality assurance and testing process to ensure it performs to OEM specifications. We stand behind our products with a comprehensive 1-year warranty, offering you peace of mind and reliable performance at a significant cost saving compared to new equipment.

Generally, it is best practice to use brand-specific transceivers to ensure full compatibility and avoid potential operational issues. While some third-party modules may work, using brand-matched SFPs in your equipment guarantees performance and support as intended by the manufacturer.

A 1000Base-T SFP module is a copper transceiver. It uses a standard RJ-45 connector and allows you to establish a 1 Gigabit Ethernet connection over standard Category 5 (Cat5) or better copper network cabling, typically for distances up to 100 meters within your facility.

All of our 1G SFP transceiver modules are backed by Terabit Systems' rock-solid 1-year replacement or full refund warranty. This guarantee is a testament to our confidence in our rigorous testing process and ensures that your investment is protected against any potential hardware failures.

The right module depends on your switch model, the type of cable you are using (single-mode fiber, multi-mode fiber, or copper), and the distance you need to cover. Our team of networking specialists is available to help you verify compatibility and select the perfect transceiver for your specific application.
