1000Base-BX Downstream Transceiver

This single-mode fiber SFP module operates at 1 Gbps with a 1490 nm transmit and 1310 nm receive wavelength. It reaches up to 10 km over an LC duplex connection. The unit is programmed for Extreme Networks 10056 compatibility.

Pairing Requirement

This downstream transceiver must be paired with the matching upstream module, StarTech.com model 10057-ST, to establish a bi-directional link. It suits network engineers extending Extreme Networks gear over single-mode fiber. Buyers without the upstream counterpart cannot complete the link.

1490 nm Tx / 1310 nm Rx Wavelength Pair

The fixed wavelength assignment determines which end of the fiber this module occupies. Verify that your existing infrastructure uses the complementary 1310 nm Tx / 1490 nm Rx upstream device before purchasing.

Questions about this item

How do I verify the 10056-ST is operating correctly after installation?

Check the switch port status for a 1 Gbps link light and confirm error-free traffic over the LC single-mode fiber connection at 1490nmTx/1310nmRx.

What comes with the 10056-ST and what must I purchase separately?

The box includes one SFP transceiver; you must supply an LC single-mode fiber patch cable and the upstream 10057-ST module to complete the 10 km link.

Which wavelength version should I select for a downstream 1000Base-BX connection?

Choose the 10056-ST with 1490nmTx/1310nmRx for the downstream side; pair it with the 10057-ST which uses the reverse wavelengths.
