Compatible 10 Gbps Upstream Transceiver

The STARTECH SFP-10G-BXU-I-ST is a Cisco SFP-10G-BXU-I compatible SFP+ transceiver module. It delivers 10 Gbps Ethernet connectivity over single-mode fiber using an LC duplex connector. The module is programmed and tested for interoperability with 10GBase-BX compatible Cisco switches and routers.

Suits 10 km Single-Mode Links Needing Upstream

This transceiver suits network engineers building or extending 10 Gigabit links up to 10 km (6.2 mi) over SMF where the upstream wavelength is 1270 nm and downstream is 1330 nm. It is not for deployments requiring the opposite wavelength pairing, multimode fiber runs, shorter-reach optics, or data rates other than 10 Gbps.

Stable 10 Gbps Output Over 10 km SMF

Under sustained load the module maintains a steady 10 Gbps transfer rate across the full 10 km distance on single-mode fiber. The fixed 1270 nm transmit and 1330 nm receive wavelengths ensure consistent optical performance without the signal drift that can affect unqualified optics during prolonged operation.

Highlights

  • 10 Gbps throughput for high-speed fiber links
  • Up to 10 km reach over single-mode fiber
  • LC duplex connector for secure patching
  • 1270 nm Tx / 1330 nm Rx wavelengths for upstream pairing
  • Cisco SFP-10G-BXU-I compatible for drop-in deployment

Questions about this item

Which SFP+ port type must my switch or router have for this module to seat correctly?

The module uses an LC duplex connector and fits any standard SFP+ cage that accepts LC single-mode fiber.

Will this upstream transceiver link with the downstream SFP-10G-BXD-I-ST I already have?

Yes, the 1270 nm transmit and 1330 nm receive wavelengths are matched to the SFP-10G-BXD-I-ST for a 10 Gbps bidirectional link over 10 km.

What should I check in the switch interface counters to confirm the link is healthy?

Verify the port shows 10 Gbps speed, no CRC errors and a receive power level within the single-mode range for 10 km.
