SFP+ transceiver CBO SFP-10G-BX-U-40KM-PA-BO 10 Gbit/s LC single-mode 40 km

CBO SFP-10G-BX-U-40KM-PA-BO is an SFP+ optical transceiver module that provides 10 Gbit/s data transmission over single-mode fiber using an LC connector. Engineered for uplink and long-reach links in switches and routers, this module supports distances up to 40 km and is intended for deployment in data centers, carrier networks and enterprise infrastructures that require reliable 10G connectivity.

Advantages

The transceiver offers a compact SFP+ form factor compatible with standard 10G ports, low power consumption and stable optical performance for long-distance links. Its single-mode LC interface ensures interoperability with common fiber cabling and supports dense network topologies while maintaining signal integrity across up to 40 km. The module is designed for hot-pluggable installation and passive cooling in rack-mounted network equipment.

Suitable for

• 10G uplinks between switches and aggregation devices
• Long-reach connections in data centers and colocation facilities
• Carrier and metro networks requiring single-mode optical links
• Enterprise WAN links and campus backbone segments

Key specifications

• Data rate: 10 Gbit/s
• Fiber type: single-mode
• Connector: LC duplex
• Maximum link length: up to 40 km (single-mode fiber)
• Form factor: SFP+
• Optical interface: bidirectional (BX) suitable for wavelength-separated transmit/receive
• Power: low-power SFP+ class operation

How to use

Install the module into an available SFP+ port on a compatible switch or router while the host device is powered according to the vendor instructions for hot-pluggable modules. Connect the LC single-mode fiber patch cable into the module’s LC receptacle, ensuring correct orientation for transmit and receive fibers. Verify link status through the host device management interface and confirm that port speed and duplex settings are configured for 10 Gbit/s operation. Perform optical power and link tests as part of standard commissioning to validate reach and signal quality.

Recommendations

For reliable long-reach performance, use single-mode fiber with appropriate attenuation characteristics and LC connectors in good condition. Match the module’s wavelength plan when deploying bidirectional (BX) links, and monitor optical power margins to avoid signal degradation. Keep firmware and driver compatibility of the host device up to date and follow manufacturer guidance for environmental operating conditions.
