Transceptor SFP+ CBO SFP-10G-BX-U-40KM-FJ-BO 10Gbit/s Fibra única LC BX‑U 40 km

CBO SFP-10G-BX-U-40KM-FJ-BO is a 10Gbps SFP+ optical transceiver module designed for single-fiber bidirectional links with LC connectors. Supporting BX‑U operation and a maximum reach of 40 km, the module provides a compact, hot-pluggable solution for long-distance uplinks and metro connections. It is suitable for insertion into SFP+ ports on switches, routers and other fiber networking equipment where a single-fiber duplex replacement is required.

Advantages

The transceiver offers 10 Gbps full-rate data transmission over a single optical fiber using bidirectional (BX) signalling, reducing fiber cabling requirements. Its LC connector and SFP+ form factor ensure compatibility with a wide range of network devices and enable hot-pluggable installation without powering down equipment. With a specified link distance of up to 40 km, it meets common metro and long-haul uplink needs while maintaining a small physical footprint.

Suitable for

• 10 Gigabit uplinks between switches and aggregation devices in metro environments
• Long-distance point-to-point links where single-fiber (bidirectional) connections reduce fiber usage
• Data center interconnects and campus backbone links requiring 40 km reach
• Replacement or upgrade of existing SFP+ modules to support BX‑U single-fiber operation

Key specifications

• Data rate: 10 Gbps (SFP+ compatible)
• Optical interface: LC single-fiber bidirectional (BX‑U)
• Maximum reach: up to 40 km over single-mode fiber
• Wavelengths: bidirectional transmit and receive on distinct wavelengths (BX operation)
• Form factor: SFP+ hot-pluggable transceiver
• Use case: long-distance uplinks, metro and campus backbones

How to use

Install the module into an available SFP+ slot on a compliant switch, router or fiber transceiver port until it seats securely. Connect a single-mode fiber cable with LC connectors, observing transmit/receive orientation for bidirectional operation. Verify link status and speed through the network device management interface. No software drivers are required for standard SFP+ ports; ensure the device firmware supports third-party transceivers if applicable.

Recommendations

To achieve reliable 40 km links, use appropriate single-mode fiber (G.652/G.657 as applicable), maintain clean LC connectors, and follow device vendor guidance on compatibility. Allow proper ESD precautions during handling and avoid bending the fiber beyond recommended radius for long-term performance.
