SFP transceiver CBO SFP-10G-BX-D-40KM-NV-BO 10G single‑fiber 40 km

The CBO SFP-10G-BX-D-40KM-NV-BO is a 10 Gigabit single-fiber SFP transceiver designed for BiDi (bidirectional) fiber links up to 40 km. This compact optical module supports 10G Ethernet data rates and fits standard SFP cages used in switches, routers and other compatible networking equipment. It provides a long-reach optical connection over a single fiber strand, enabling uplinks and point-to-point links without requiring a separate transmit and receive fiber pair.

Advantages

This SFP transceiver offers 10G performance with single-fiber BiDi operation, reducing fiber cabling requirements and simplifying deployment in fiber-constrained environments. The compact SFP form factor allows broad compatibility with equipment that accepts hot-pluggable SFP modules. Designed for long-reach links up to 40 km, the module supports reliable transport for metro connections, campus backbones and enterprise uplinks while keeping power consumption and heat generation low.

Suitable for

• 10G uplinks between switches and routers over single-fiber BiDi links
• Metro aggregation and point-to-point fiber connections up to 40 km
• Enterprise backbone and data center interconnects requiring long-reach optics
• Upgrades where fiber count is limited and single-fiber solutions are preferred

Key specifications

• Data rate: 10 Gigabit Ethernet
• Fiber type: single-mode (single-fiber BiDi operation)
• Maximum reach: up to 40 km
• Form factor: SFP (hot-pluggable)
• Interface: LC connector compatibility for optical fiber
• Transmission: bidirectional on a single fiber strand (separate TX and RX wavelengths)

How to use

Insert the SFP transceiver into an appropriate SFP slot on a compatible switch, router or optical device while the host port is powered down or per the equipment vendor’s hot-swap guidance. Connect an LC-terminated single-mode fiber patch cable between the module and the remote BiDi module; ensure correct orientation so the transmit wavelength on one end matches the receive wavelength on the other end. Verify link status and configure link settings on the host device for 10G operation as required. Follow standard handling precautions for optical modules to avoid damage from electrostatic discharge and contamination of optical interfaces.

Recommendations

Use clean LC connectors and inspect fiber endfaces before mating. Match BiDi transceivers with complementary wavelength pairs and ensure the fiber route supports single-mode operation for the specified reach. Monitor port temperature and optical power levels through the host device to confirm proper operation and to detect potential margin issues.
