BIDI SFP Transceiver for 20 km Single-Mode Links

This bidirectional SFP module transmits at 1550 nm and receives at 1310 nm over a single strand of single-mode fibre. It supports a 1.25 Gbps data rate and is designed for Gigabit Ethernet 1000BASE-BX10-D and 1 Gbps Fibre Channel applications. The module uses a simplex LC connector and operates on a 3.3 V supply.

Practical Limits of the 1000BASE-BX10-D Interface

The transceiver is specified for a 20 km reach over single-mode fibre when paired with a matching Tx1310 nm/Rx1550 nm module. It complies with the IEEE 802.3 ah 1000BASE-BX10-D standard and the INF-8074i SFP MSA. Operating temperature range is 0 °C to 70 °C. Digital diagnostics are available via the two-wire SFF-8472 interface.

Compatibility Checks Before Ordering

The module must be coded for the specific switch or router brand and model where it will be installed; the supplier requires this information before dispatch. Confirm that the host equipment supports 1000BASE-BX10-D bidirectional optics and accepts third-party SFP modules. Verify that the link partner uses the complementary Tx1310 nm/Rx1550 nm wavelength pair.

Questions about this item

Which distance version should I choose for a 20 km single-mode link?

The SFP-1000BX20-U5 or SFP-1000BX20-D5 models are rated for 20 km over single-mode fiber; select the U5 or D5 variant that matches the Tx/Rx wavelength pairing required by your equipment.

What does the 1.25 Gbps rate mean when installed in a switch?

The module runs at 1.25 Gbps for Gigabit Ethernet 1000BASE-BX10 and at 1.0625 Gbps for 1GFC Fibre Channel, so actual throughput matches the protocol you configure on the port.

What interface standard does the SFP MSA compliance cap in practice?

INF-8074i SFP MSA compliance ensures mechanical and electrical fit in any standard SFP cage, while the 2-wire SFF-8472 interface enables diagnostic monitoring but does not alter the 1.25 Gbps line rate.
