Single-fibre SFP for 40 km links

The Axiom 3HE04324AA-AX is a 1000BASE-BX40-U SFP transceiver built for Enterasys equipment. It transmits at 1310 nm and receives at 1490 nm over a single strand of single-mode fibre. Network engineers use it to extend gigabit connections across campus or metro distances without laying additional fibre pairs.

Wavelength split limits reach and pairing

The 1310 nm transmit and 1490 nm receive wavelengths mean the module must be paired with a matching downstream transceiver using the opposite wavelengths. Single-mode fibre is required; multimode cable will not support the 40 km distance. The LC duplex interface carries both directions on one fibre, so any contamination or bend loss on that single path affects both transmit and receive.

Hot-plug SFP installs in seconds

The SFP form factor slides into any compatible Enterasys port without tools or power-down. The LC connector clicks into place, but the small ferrule is easily scratched if the dust cap is removed too early. Verify the switch port is configured for 1000BASE-BX40-U before insertion, otherwise the link will not come up.

Questions about this item

Should I pick the upstream TX 1310 nm model or the downstream TX 1490 nm model?

Choose this upstream unit when your link partner uses a downstream transceiver that transmits at 1490 nm and receives at 1310 nm; the wavelengths must mirror each other on the same fibre.

What does the 1000 Mbps rating deliver in a live switch?

It provides a full-duplex 1 Gbps Ethernet link over single-mode fibre, limited by the 40 km reach and the LC connector budget.

Which SFP standard governs the LC interface and what distance does it cap?

The module follows the 1000BASE-BX40-U specification, which defines the LC single-mode interface and caps the guaranteed reach at 40 km.
