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.
