SFP+ transceiver CBO SFP-10G-BX-D-40KM fiber optic 10G 40 km

The CBO SFP-10G-BX-D-40KM is a compact SFP+ transceiver from BlueOptics designed to deliver 10 Gbps optical connectivity over single-mode fiber up to 40 km. The module follows the SFP+ form factor for straightforward insertion into compatible switches, routers and transceivers cages. It implements a bidirectional single-fiber (BX-D) link for point-to-point uplinks and metro connections where separate transmit and receive fibers are not available or where fiber count conservation is required.

Advantages

This SFP+ transceiver provides 10 Gbps line rate with a long reach of up to 40 km on single-mode fiber, enabling long-distance links without intermediate amplification. The single-fiber bidirectional design reduces fiber cabling requirements and simplifies provisioning in dense environments. The standard SFP+ form factor ensures broad compatibility with enterprise and carrier-grade network equipment that accepts hot-swappable modules, allowing rapid replacement or upgrades with minimal downtime.

Suitable for

• Data center interconnects and server uplinks
• Enterprise WAN links and branch connectivity
• Metro network aggregation and ring connections
• Telecom access networks and ISP backbone links

Key specifications

• Interface: SFP+ form factor, hot-pluggable
• Data rate: 10 Gbps
• Fiber type: single-mode fiber (SMF)
• Reach: up to 40 km (single-mode)
• Connector type: single-fiber bidirectional (Bx-D) using appropriate duplexing or WDM adapter
• Wavelength: asymmetric transmit/receive wavelengths for bidirectional operation
• Power class: low-power SFP+ module suitable for switch/router transceiver slots

How to use

Install the transceiver into a compatible SFP+ port until it clicks into place; the module is hot-swappable so the host device does not usually need to be powered down. Connect the single-mode fiber through an appropriate WDM or single-fiber patch solution matching the module's transmit and receive wavelengths and ensure correct directional alignment. Verify link status and speed in the host device management interface and monitor signal and error counters to confirm reliable operation.

Recommendations

Use high-quality single-mode fiber and compatible WDM components to achieve the specified 40 km reach. Confirm that the network equipment supports third-party SFP+ modules and, if necessary, enable compatible vendor settings in the switch or router. Follow ESD precautions when handling the transceiver and keep optical connectors clean to prevent signal loss.
