The StarTech SFP-10G-BXU-I-ST is a Cisco-compatible 10GBase-BX upstream SFP+ fiber transceiver for network administrators equipping compatible Cisco switches or routers with 10 GbE links over single-mode fiber, up to 10 km.
Recommended For
- Network technicians connecting Cisco-compatible switches or routers across single-mode fiber who need a 10Gbps BiDi link over one fiber strand; this upstream module must be paired with a downstream BX module.
- Teams extending a 10GbE connection between buildings or network closets over an existing single-mode fiber strand, with a link distance within the module’s 10 km rating.
- Network operators upgrading a compatible device’s SFP+ port or replacing an optic who want a hot-swappable module with digital diagnostics monitoring.
- Installers conserving fiber strands on a point-to-point 10GbE run, provided both endpoints use compatible BiDi optics with complementary transmit and receive wavelengths.
Real-World Use Scenarios
- When linking a core switch to a remote building or network closet over existing single-mode fiber, use this module with a matching downstream BiDi module at the far end to carry a 10GbE link over one fiber strand, for routes within the link’s supported reach and optical limits.
- When a campus or business has limited fiber strands available, this can provide a 10GbE connection while leaving other strands available for separate links or future use; the far end must use the opposite-wavelength BiDi module.
- For a switch-to-switch or router-to-switch uplink where the installed route has only one usable single-mode strand, a correctly matched BiDi pair can carry both traffic directions without requiring a second strand.
- When adding a 10GbE connection between network rooms across a longer single-mode fiber route, this module can avoid a copper run; confirm the switches support the transceiver and that the route is within the specified reach.
