1000BASE-BX-U SFP transceiver

This Extreme Networks 10057H module is a hot-swappable SFP transceiver that provides a single 1000Base-BX-U optical interface. It connects to network equipment through an LC connector and is qualified for use in compatible Extreme Networks switches and I/O modules.

Network teams extending fibre links

Engineers who need a bidirectional single-fibre uplink at 1000 Mbps will find this part matches that requirement. Teams requiring multi-mode SR, long-range LR or extended-range ZR optics should select a different module from the same qualified family.

Single-strand BX-U wavelength pairing

The decisive specification is the 1000Base-BX-U standard, which defines the transmit and receive wavelengths for single-strand fibre operation; verify that the opposite end of the link uses the complementary BX-D module before purchasing.

Questions about this item

How much power does the 10057H SFP draw when running continuously in a switch?

The module is a passive 1000Base-BX-U transceiver with no active cooling, so its power draw is minimal and handled entirely by the host switch port.

What cabling and patch-panel connectors must I already have to use the LC interface on this transceiver?

You need single-mode fibre terminated with LC duplex connectors that match the 1000Base-BX-U wavelength pair for the desired link distance.

Will the 10057H work in an older Extreme Networks switch that only supports standard 1000Base-LX SFPs?

The 10057H uses a single-fibre BX-U wavelength scheme, so it requires a matching BX-D module at the far end and a switch port that accepts BX optics.
