SFP+ module CBO SFP-10G-BX-U-40KM-CI-BO 10 Gbit/s single‑fiber LC up to 40 km

CBO SFP-10G-BX-U-40KM-CI-BO is an SFP+ transceiver module that enables 10 Gbit/s bidirectional data transmission over a single optical fiber using an LC connector. Designed for point-to-point links up to 40 km, this compact hot-pluggable module fits standard SFP+ ports on switches, routers and optical equipment. It is intended for network uplinks and metro or long-reach connections where duplex fiber is limited, offering a space-saving alternative to duplex modules while maintaining high-speed connectivity.

Advantages

The module supports 10 Gbit/s data rate with single‑fiber bi-directional operation, reducing cabling requirements in constrained fiber environments. Its LC interface and compact SFP+ form factor allow easy hot-pluggable installation and replacement without powering down equipment. The transceiver is suitable for longer links up to 40 km, enabling flexible network design for metro and long‑reach scenarios while preserving port density on network devices.

Suitable for

• 10 Gbit/s uplinks between switches and routers in data centers and enterprise networks
• Metro networks and long-reach connections where duplex fiber is unavailable
• Upgrading equipment to support single‑fiber, bi‑directional links while maintaining existing fiber infrastructure
• Compact installations that require hot‑pluggable transceivers with LC connectors

Key specifications

• Wavelength: bi‑directional single‑fiber operation (separate transmit and receive wavelengths)
• Data rate: 10 Gbit/s
• Connector type: LC
• Maximum link distance: up to 40 km over appropriate single‑mode fiber
• Form factor: SFP+ hot‑pluggable
• Application: single‑fiber, bi‑directional optical links for uplink and metro/long‑reach use

How to use

Insert the transceiver into a compatible SFP+ port on the network device until it locks into place, then connect the single optical fiber using LC connectors following the module's transmit/receive orientation. Ensure the connected fiber, patch panels and any intermediate equipment are rated for single‑mode operation and that link budgets account for the specified maximum distance. Configure the network device port for 10 Gbit/s operation and verify link status and optical levels after installation.

Recommendations

Use the module with compatible SFP+ ports and single‑mode fiber infrastructure. Confirm transmit and receive wavelengths and test link performance after installation. For distances near the 40 km limit, check loss budgets and consider additional testing to ensure reliable operation.
