SFP+ transceiver CBO SFP-10G-BX-U-40KM-MR-BO 10 Gbit/s single‑fiber LC, 40 km, upstream

CBO SFP-10G-BX-U-40KM-MR-BO is an SFP+ optical transceiver module that delivers 10 Gbit/s data rate over a single optical fiber using an LC connector. Built for upstream (BX-U) bi-directional transmission, the module supports link distances up to 40 km and fits the compact SFP+ form factor for hot-swap installation in compatible switches, routers and optical line terminals. The design is suitable for service provider aggregation, metro and long-reach connections where single-fiber connectivity and space-efficient ports are required.

Advantages

The transceiver provides 10 Gbit/s throughput on a single fiber, reducing fiber infrastructure requirements by enabling bi-directional traffic with one strand. Its SFP+ form factor allows hot-swapping and high port density in existing equipment racks. The LC connector ensures wide compatibility with standard fiber patching panels and pre-terminated cabling. The module is intended for upstream (BX-U) deployment, simplifying network design for asymmetric links between sites.

Suitable for

• Service provider aggregation and access networks
• Metro fiber links and campus backbone segments
• Long-reach uplinks between customer sites and central offices (up to 40 km)
• Equipment with SFP+ slots requiring single-fiber bi-directional transceivers

Key specifications

• Data rate: 10 Gbit/s
• Fiber type: single-mode, single-fiber bi-directional
• Connector: LC duplex physical interface (single-fiber operation)
• Max reach: up to 40 km (link dependent)
• Form factor: SFP+ hot-swappable module
• Application direction: upstream (BX-U) bi-directional transmission

How to use

Insert the SFP+ module into a compatible SFP+ port on a switch, router or optical line terminal while the host device is powered according to the equipment manual to enable hot-swap functionality. Connect a single-mode fiber patch cord with LC connectors, ensuring the transmit and receive wavelengths or pairings follow the upstream (BX-U) configuration required by the remote downstream module. Verify link status on the host device and monitor signal quality and error counters via the management interface to confirm proper operation.

Recommendations

Use certified single-mode fiber and correct LC patch cords; maintain clean connector endfaces and follow transceiver vendor guidelines for maximum reach and optical power budgets. Match this upstream module with the corresponding downstream (BX-D) transceiver type and confirm compatibility with the host device firmware and vendor-supported transceiver list.
