BIDI SFP 1.25G 40KM for Gigabit Ethernet

This bidirectional SFP transceiver delivers 1.25 Gbps over single-mode fibre up to 40 kilometres. It uses a 1550 nm DFB laser transmitter and receives at 1310 nm through a simplex LC connector. The module suits Gigabit Ethernet 1000BASE-BX-D and 1 GFC fibre channel links in commercial temperature environments.

Hot-plug installation with vendor coding required

The transceiver is hot-pluggable and compliant with the INF-8074i SFP MSA, so it slides into a live SFP cage without tools. A two-wire SFF-8472 interface enables diagnostic monitoring once seated. The supplier must pre-program the module with the correct vendor code for your specific switch or router; an uncoded unit will not link.

Verify single-mode fibre and TX/RX wavelength match

Confirm your link uses single-mode fibre rated for at least 40 kilometres and that the far-end transceiver transmits at 1310 nm and receives at 1550 nm. The host equipment must accept a +3.3 V SFP module and support 1000BASE-BX-D or 1.0625 Gbps fibre channel. Provide the exact switch brand and model to the supplier before ordering so the correct coding is applied.

Questions about this item

How can I verify the 1.25Gb/s link is operating correctly after inserting the module?

Check the switch port status for a 1.25Gb/s link, confirm the Tx1550nm/Rx1310nm wavelengths appear in the DOM readout, and ensure the SFF-8472 diagnostic monitor reports normal temperature, voltage and optical power levels.

What comes in the box and what extra items are required for installation?

The transceiver module with a simplex LC connector is supplied; you must provide single-mode fibre patch cables and a compatible SFP host port that accepts the 1000BX-D coding for your switch brand.

Which distance version should I select for a 40km single-mode run?

Choose the SFP-1000BX40-U5 or SFP-1000BX40-D5 model; both are rated for 40km over SM fibre at 1.25Gb/s with Tx1550nm/Rx1310nm wavelengths.
