The StarTech.com 10056-ST is an Extreme Networks-compatible 1GbE downstream SFP transceiver for 1000Base-BX-D switches and routers. It is suited to single-mode fiber links up to 10 km and pairs with the StarTech.com 10057-ST.
Recommended For
- Network administrators adding or replacing a 1GbE fiber link in a compatible Extreme Networks switch or router, who need an Extreme 10056-compatible downstream SFP.
- IT teams connecting two network points over an existing single-mode fiber strand, when the link is 1GbE, within the nominal 10 km reach, and the far end has the complementary 1000BASE-BX-U optic.
- Building or campus network operators who want a bidirectional 1GbE fiber connection over one strand rather than using a separate fiber strand for each direction.
Real-World Use Scenarios
- Connecting an Extreme Networks switch to a remote switch across a campus or between nearby buildings: pair this downstream module with a compatible 1000BASE-BX-U module at the other end to carry a 1 GbE link over one strand of single-mode fiber, up to the supported link distance.
- Linking a remote wiring closet or IDF to a central switch over installed single-mode fiber: the paired BiDi optics let the network team establish a full-duplex 1 GbE connection using a single fiber strand rather than a two-strand duplex link.
- Expanding or reusing a fiber route when only one strand is available: this module can support a bidirectional link on that strand when paired with the opposite-wavelength upstream optic, helping avoid the need to allocate a second strand for the connection.
- Replacing a failed or aging optic in a compatible Extreme Networks switch or router: the hot-swappable module can be changed without removing the device from service, helping limit disruption while the fiber link is restored.
- Connecting network equipment across a longer single-mode fiber run within a site: the link can serve 1 GbE traffic over distances up to 10 km when the far-end optic, switch compatibility, and fiber installation are suitable.
