The StarTech.com SFP-10G-BXD-I-ST is a Cisco-compatible 10GBASE-BX SFP+ transceiver for network teams connecting compatible switches or routers over single-mode fiber, carrying 10 GbE up to 10 km on one fiber strand when paired with the matching upstream module.
Recommended For
- Network teams extending a 10GbE link between buildings or sites over existing single-mode fiber when only one fiber strand is available; this downstream module is intended to pair with a complementary upstream BiDi optic.
- IT teams upgrading a Cisco-compatible switch or router link to 10GbE while reusing a single-strand single-mode fiber path, rather than installing a second fiber strand.
- Operators adding a 10GbE point-to-point connection on a single-mode fiber run up to the optic’s rated 10 km reach, provided the far-end optic uses the complementary wavelength direction.
Real-World Use Scenarios
- When two compatible switches or routers need a 10 GbE link over a single strand of single-mode fiber, use this downstream module with a matching BXU module at the other end; the pair carries traffic in both directions over that strand.
- If a site has limited fiber strands available, this BiDi link can use one strand for a 10 GbE connection instead of requiring a separate transmit and receive strand, leaving other strands available for other links.
- To connect network equipment in separate rooms or buildings over an existing single-mode fiber route, use a matched BXD/BXU pair; the module is specified for links up to 10 km, subject to the route and equipment being compatible.
- When upgrading a link to 10 GbE without installing another fiber strand, this module can reuse an existing single-mode fiber run, provided both devices support the optics and the far end has the matching upstream module.
- During maintenance or replacement on a compatible switch or router, the hot-swappable module can be changed without removing the device from service; the effect on traffic depends on the network setup and redundancy.
