SFP+ transceiver CBO SFP-10G-BX-U-40KM-DE-BO, 10 Gbit/s, LC, single-fiber BX-U, up to 40 km

CBO SFP-10G-BX-U-40KM-DE-BO is a compact SFP+ optical transceiver module for 10 Gbit/s high-speed links. The module uses an LC connector and single-fiber bidirectional (BX-U) transmission to provide a full-duplex 10 Gbit/s connection over a single fiber strand. Engineered for up to 40 km reach, it is suitable for uplinks between switches, long-distance connections between network devices and media conversion applications in data center and enterprise environments. The hot-pluggable form factor supports easy installation and replacement without powering down the host equipment.

Advantages

The SFP+ transceiver offers space-saving SFP+ form factor and compatibility with a wide range of 10 Gbit/s ports. Single-fiber BX-U operation reduces fiber cabling requirements by transmitting and receiving on one fiber using different wavelengths, simplifying fiber management and lowering infrastructure costs. Built for a 40 km link budget, the module supports long-reach connections while maintaining low power consumption and reliable optical performance for demanding network topologies.

Suitable for

• 10 Gbit/s uplinks between switches and routers in enterprise networks
• Long-distance single-fiber links between buildings or data halls up to 40 km
• Media converters and optical multiplexing systems requiring bidirectional single-fiber operation
• Compact installations and hot-swap environments where SFP+ density is important

Key specifications

• Data rate: 10 Gbit/s
• Connector type: LC duplex interface (single-fiber BX-U operation)
• Transmission mode: Bidirectional single-fiber (BX-U)
• Maximum reach: up to 40 km over single-mode fiber
• Form factor: SFP+ hot-pluggable module
• Optical wavelengths: separate transmit and receive wavelengths for BX-U operation
• Typical power consumption: low-power design suitable for dense installations

How to use

Insert the SFP+ transceiver into a compatible 10 Gbit/s SFP+ port on the switch, router or media converter until it seats securely and the retaining latch engages. Connect an LC single-fiber cable that supports bidirectional BX operation, ensuring the correct orientation between transmit and receive wavelengths at each end of the link. Verify link status and diagnostics via the host system management interface. For hot-swap replacement, remove the module by disengaging the latch and pulling it straight out, then install the replacement without powering down the host if the system supports hot-plug operation.

Recommendations

Use single-mode fiber with appropriate attenuation and connector quality for reliable 40 km links. Match BX-U wavelength plans between both ends and confirm compatibility with the host device vendor if vendor-lock checks are implemented. Avoid bending the fiber beyond recommended minimum bend radius and maintain clean LC connectors to preserve signal integrity.
