CBO SFP+ module SFP-10G-BX-D-40KM-CH-BO 10 Gbit/s single‑fiber LC 40 km

The CBO SFP+ SFP-10G-BX-D-40KM-CH-BO is a 10 Gbit/s single-fiber SFP+ transceiver with an LC connector designed for long-reach fiber links up to 40 km. It enables 10 Gigabit Ethernet connections over a single strand of single-mode fiber by using wavelength-division multiplexing for transmit and receive channels. The module is intended for use in 10GbE switches, routers and optical line equipment in data centers, carrier networks and enterprise backbone environments.

Advantages

This SFP+ module provides high-speed 10 Gbit/s throughput while minimizing fiber infrastructure by supporting bidirectional duplex communication on a single fiber. Its LC form factor and SFP+ compatibility allow easy integration into standard 10GbE ports. The design supports long-distance links up to 40 km on single-mode fiber, making it suitable for connecting dispersed sites or extending backbone segments without additional fiber pairs.

Suitable for

• 10 Gigabit Ethernet uplinks between switches and routers
• Long-distance single-mode fiber links up to 40 km
• Carrier and metro access networks requiring single-fiber solutions
• Data center interconnects and enterprise backbone extensions

Key specifications

• Data rate: 10 Gbit/s
• Connector type: LC
• Fiber type: single-mode fiber (single strand duplex operation)
• Maximum reach: up to 40 km
• Operation: wavelength-division duplex (separate TX/RX wavelengths over one fiber)
• Form factor: SFP+ module compatible with standard 10GbE ports
• Typical application: 10 Gigabit Ethernet links

How to use

Install the module into an available SFP+ slot on a compatible switch, router or media converter, ensuring the host device supports 10 Gbit/s SFP+ transceivers and single-fiber bidirectional optics. Connect an LC single-mode patch cable between transceivers at both ends, taking care to match the appropriate transmit and receive wavelengths according to equipment documentation. Verify link status and network configuration on the host device and monitor signal levels and error counters after installation.

Recommendations

For reliable operation, use certified single-mode fiber and LC connectors in good condition, follow proper fiber cleaning procedures before mating connectors, and verify compatibility with the host equipment. When planning links, account for fiber attenuation, connector and splice losses to ensure margin for the 40 km reach.
