1.25 Gbps SFP Transceiver for 20 km Links

This transceiver delivers a 1.25 Gbps data rate over single-mode fibre at 1310 nm wavelength. It uses a duplex LC connector and reaches up to 20 km link distance. The module complies with IEEE 802.3z Gigabit Ethernet and Fiber Channel 1GFC standards. It operates on a single 3.3 V supply and is hot-pluggable for live installation.

Verify Host Equipment Coding Before Order

You must confirm the exact brand and model of the switch or router that will host this module. The supplier requires that information to program the correct vendor coding into the transceiver. Without proper coding the module may not be recognised by the host device. The unit supports the 2-wire management interface defined in SFF-8472 for diagnostics.

Fits Standard SFP Slots with MSA Compliance

The transceiver follows the INF-8074i SFP MSA form factor, so it fits any standard SFP port that accepts MSA-compliant modules. It frees a copper port for long-haul fibre connectivity while drawing power from the host slot. The commercial temperature range of 0 °C to 70 °C suits typical indoor network environments. Certificates include RoHS, REACH, FCC and UL.

Questions about this item

Does the SFP-1000LX20 include the duplex LC patch cables or must they be purchased separately?

The transceiver has a duplex LC connector built in, but single-mode patch cables are not included and must be bought separately.

When should I choose the SFP-1000LX20 instead of the 10 km LX or the 40 km LHX model?

Choose the LX20 when the single-mode link distance is up to 20 km; the LX covers 10 km and the LHX reaches 40 km.

What does the 1.25 Gbps rate mean for actual throughput in a Gigabit Ethernet switch?

The module runs at line-rate 1.25 Gbps, delivering full 1000BASE-LX throughput with a 1310 nm FP laser over single-mode fiber.
