BIDI SFP Transceiver 80km 1.25Gbps

This bidirectional SFP transceiver delivers 1.25Gbps data rates over single-mode fibre at distances up to 80km. It uses a Tx1550nm/Rx1490nm wavelength pair and a simplex LC connector for single-strand fibre deployments. The module is hot-pluggable and complies with the INF-8074i SFP MSA for mechanical and electrical interchangeability. It operates on a single 3.3V supply and is suited for Gigabit Ethernet and 1GFC Fibre Channel links.

1000BASE-BX-D interface and distance limits

The transceiver follows the IEEE 802.3ah 1000BASE-BX-D standard for bidirectional Gigabit Ethernet on single-mode fibre. Rated reach is 80km, assuming standard SM fibre attenuation and connector loss budgets. It also meets Fibre Channel 100-SM-LC-L specifications for 1.0625Gbps operation. A two-wire management interface compliant with SFF-8472 provides digital diagnostic monitoring of temperature, voltage, and optical power. Performance beyond the rated distance is not guaranteed.

Compatibility and coding requirements

The module is coded for specific switch and router brands such as Cisco and Juniper, so the host equipment brand and model must be confirmed before ordering. Custom coding is available but requires the exact target device details. Verify that your hardware supports SFP MSA modules, accepts 3.3V power, and can enable the SFF-8472 diagnostic interface if monitoring is needed. Buyers who need multi-vendor stock without pre-configuration or who require a different wavelength pair or reach should select another variant.

Questions about this item

Should I pick the 80 km version or one of the shorter-distance models?

Choose the 80 km module when your single-mode fiber link runs up to 80 km; shorter-reach models such as 2 km, 10 km, 20 km, 40 km or 60 km cover lesser distances, while 100 km, 120 km and 140 km versions exist for longer spans.

What does the 1.25 Gbps rate mean once the transceiver is installed in a switch?

The module delivers a 1.25 Gbps line rate for Gigabit Ethernet 1000BASE-BX and 1.0625 Gbps for 1 Gbit Fibre Channel, so throughput matches the port speed of the host equipment.

Which SFP standard does the module follow and what does that limit?

It complies with INF-8074i SFP MSA and SFF-8472 diagnostic monitoring, ensuring mechanical fit, hot-plug operation and management interface compatibility in any MSA-compliant SFP cage.
