The StarTech.com SFP1000BXUST is a hot-pluggable 1 Gbps 1000BASE-BX upstream SFP transceiver for compatible network equipment, supporting single-mode fiber connections up to 10 km with an LC connector. It suits network administrators extending Gigabit Ethernet links over fiber.
Recommended For
- Network administrators extending a 1 GbE link between switches or routers over existing single-mode fiber, when the equipment accepts an uncoded, MSA-compliant SFP.
- IT teams connecting network endpoints over a single fiber strand, provided the far end uses a compatible 1000BASE-BX downstream transceiver with opposite transmit and receive wavelengths.
- Technicians replacing or adding an upstream optic on an existing 1000BASE-BX link that uses 1310 nm transmit and 1490 nm receive wavelengths.
- Organizations extending gigabit connectivity across a single-mode fiber run within the module’s specified 10 km reach, without needing a higher-than-1-GbE link.
Real-World Use Scenarios
- Link two SFP-equipped switches across buildings over an existing single-mode fiber strand; paired upstream and downstream BiDi modules let the connection carry traffic in both directions while leaving a second strand available.
- Connect a main-site switch to a compatible switch or router at a remote office, warehouse, or campus building; the fiber link can carry a 1GbE connection over a run within the module’s supported reach.
- Use a single available fiber strand when a site-to-site cabling route has limited fiber capacity; the paired BiDi optics send and receive on different wavelengths over that strand.
- Add a fiber uplink between compatible network devices in a small campus or business network; users can extend the wired LAN to another location without running a separate copper Ethernet cable between the sites.
- Replace or install an SFP during network maintenance in a compatible device; its hot-pluggable design can simplify module changes, while actual link operation depends on host compatibility and using the matching downstream optic at the other end.
