BIDI SFP transceiver 1.25G 2KM

This bidirectional SFP transceiver operates at 1.25 Gbps over single-mode fibre with Tx 1310 nm and Rx 1550 nm wavelengths. It reaches a 2 km link distance using a simplex LC connector and complies with IEEE 802.3 ah 1000BASE-BX-U and INF-8074i SFP MSA. The module is hot-pluggable and runs on a single 3.3 V supply.

Network engineers extending Gigabit links

The module suits engineers deploying point-to-point Gigabit Ethernet or 1 GFC links over existing single-mode infrastructure where bidirectional optics save fibre strands. It is not for installers who need longer reaches such as 10 km, 20 km or 40 km variants, nor for systems that require dual-fibre transceivers with matching Tx and Rx wavelengths.

Sustained operation at commercial temperatures

Rated for 0 °C to 70 °C, the transceiver maintains stable output during continuous traffic loads without thermal throttling. The 2-wire management interface compliant with SFF-8472 provides real-time diagnostics so operators can monitor optical power and temperature throughout extended duty cycles.

Questions about this item

What switch port type is required to accept this SFP transceiver?

A switch with an SFP cage that supports the INF-8074i MSA and supplies a single 3.3 V rail will accept this module.

Will this module link to an existing 1000BASE-BX-D device operating at 1550 nm Tx and 1310 nm Rx?

Yes, the Tx1310 nm / Rx1550 nm wavelength pair is the complementary U side for a 2 km single-mode link.

How can I confirm the link is operating at the rated 1.25 Gbps after installation?

Check the switch port status for a 1 Gbps link and verify the SFF-8472 diagnostics show a 1310 nm Tx and 1550 nm Rx wavelength reading.
