Dell SFP 1G BiDi Transceiver

This Dell SFP-1G-BX10-D transceiver provides a 1.25 Gbps bidirectional link over a single strand of single-mode fiber. It is designed for network engineers extending Dell switching infrastructure up to 10 km without adding cable pairs.

10 km Single-Mode Reach

The module transmits at 1310 nm and receives at 1490 nm, covering metro access or campus links up to 10 km. Signal budget is exhausted beyond that distance, so longer-haul or multi-mode deployments need different optics.

Hot-Swappable Simplex LC Build

A simplex LC connector and MSA-compliant SFP form factor allow insertion into compatible ports without powering down the switch. Digital diagnostics expose real-time temperature, voltage, optical power and laser bias for proactive link monitoring.

Questions about this item

Will this SFP module work in a Dell switch port that currently uses a standard duplex 1G transceiver?

Yes, the module uses the standard SFP form factor and is MSA compliant, so it fits the same Dell SFP port; you simply replace the duplex patch cord with a single strand of single-mode fiber.

How can I verify the link is healthy after installing the module?

The transceiver supports Digital Diagnostics Monitoring, letting you read real-time temperature, voltage, laser bias current and both TX and RX optical power levels from the switch CLI.

Does the package include the simplex LC patch cord needed for the single-fiber BiDi link?

No, only the transceiver itself is supplied; you must source a separate OS2 single-mode patch cable with a simplex LC connector on each end.
