Single-mode Gigabit transceiver

This bidirectional SFP module carries 1.25 Gbps over single-mode fibre using Tx 1550 nm and Rx 1310 nm wavelengths. It is built for commercial temperature ranges from 0 °C to 70 °C and suits enterprise links up to 2 km. Network engineers deploying 1000BASE-BX-D or 1 Gbps Fibre Channel connections will find it a direct fit.

Hot-pluggable SFP MSA installation

The module follows INF-8074i and plugs into any standard SFP cage without tools or power-down. A simplex LC connector reduces cabling to one fibre strand, but the link fails if the paired module uses reversed wavelengths. Coding must match the host switch brand and model; mismatched EEPROM data is the most common cause of a non-link after insertion.

Sustained 2 km operation

Continuous traffic at 1.25 Gbps stays within the 0 °C to 70 °C commercial envelope and the single 3.3 V supply rail. The 1550 nm FP laser and SFF-8472 diagnostic interface let operators monitor optical power and temperature in real time. Links beyond 2 km or in industrial temperature bands need a different module from the same series.

Questions about this item

How can I confirm the module is operating correctly after installation?

The module supports a 2-wire management interface compliant with SFF-8472, allowing real-time monitoring of temperature, voltage, and optical power levels through the host switch.

What is included with the transceiver and what must be purchased separately?

The transceiver includes a simplex LC connector for single-mode fiber; you must supply the single-mode fiber patch cable and a compatible SFP port on your switch or router.

Which wavelength variant should I select for a 2 km link?

Choose the Tx1550nm/Rx1310nm version (this module) for one end of the link and the paired Tx1310nm/Rx1550nm variant for the other end to achieve 2 km over single-mode fiber.
