Upstream 1 Gbps SFP for single-mode fiber

This upstream transceiver adds a 1 Gbps fiber link to switches or routers that accept SFP modules. It follows the IEEE 802.3z 1000BASE-BX standard and is aimed at network operators who need a single-strand bidirectional connection over single-mode fiber. The module ships new and complies with MSA dimensions for broad equipment compatibility.

MSA-compliant build with LC duplex port

The transceiver meets Multi-Source Agreement specifications, so it fits standard SFP cages without mechanical issues. An LC duplex female receptacle accepts single-mode patch cables, while the 1310 nm transmitter and 1490 nm receiver wavelengths enable upstream transmission on a single fiber pair. Operating temperature spans 0 to 70 °C and storage temperature spans -40 to 85 °C, with humidity tolerance of 5 to 95 % RH.

Verify 1000BASE-BX upstream support and LC cabling

Before ordering, confirm that your host equipment explicitly supports 1000BASE-BX upstream optics and not a different wavelength plan or downstream-only configuration. Ensure the link budget allows a 10 km reach over the single-mode fiber you have installed. Check that the SFP cage is not locked to a vendor whitelist that would reject MSA-compliant modules.

Questions about this item

What does the IEEE 802.3z 1000BASE-BX standard limit in practice?

The IEEE 802.3z 1000BASE-BX standard caps the link at 1 Gbps over single-mode fiber with a maximum reach of 10 km using 1310 nm Tx and 1490 nm Rx wavelengths.

What physical slot and connector does the SFP1000BXUST need to fit?

It requires an MSA-compliant SFP cage and connects to a duplex LC single-mode fiber patch cord.

How is the module installed, and which step is often missed?

Insert the transceiver into the SFP port until it clicks, then attach the LC duplex cable; the step often missed is removing the dust caps from both the module and cable before connecting.
