Fiber Optic SFP+ Transceiver CBO SFP-10G-BX-U-40KM — 10Gb/s, single‑fiber, 40 km

The CBO SFP-10G-BX-U-40KM is a fiber optic SFP+ transceiver module designed for 10 Gb/s data transmission over a single optical fiber up to 40 km. Intended for installation in network switches, routers and optical transport equipment, this compact hot-pluggable module uses bi-directional (BX) operation to send and receive signals on one fiber, simplifying cabling for point-to-point links and metro applications. The form factor and electrical interface match SFP+ ports, enabling straightforward replacement or capacity upgrades in 10 Gigabit Ethernet and other 10G optical systems.

Advantages

This single-fiber SFP+ transceiver supports a 10 Gb/s data rate and a reach of up to 40 km, providing a balance of speed and long-distance connectivity while reducing fiber count through bi-directional transmission. Its hot-pluggable SFP+ form factor allows easy installation and maintenance without powering down equipment. The module is suitable for integration into standard 10G optical networks and offers compatibility with common switch and router SFP+ ports, enabling flexible deployment in metro aggregation and long-reach segments.

Suitable for

• Metro Ethernet links requiring reduced fiber usage
• Point-to-point 10 Gigabit Ethernet connections up to 40 km
• Aggregation and edge interfaces in service provider networks
• Upgrading switch or router SFP+ ports for long-reach links

Key specifications

• Data rate: 10 Gb/s
• Optical mode: single-fiber, bi-directional (BX)
• Maximum reach: up to 40 km (dependent on fiber type and link budget)
• Form factor: SFP+ hot-pluggable module
• Wavelength: uses separate transmit and receive wavelengths for BX operation
• Typical applications: 10 Gigabit Ethernet, optical transport and metro networks

How to use

Insert the SFP+ transceiver into an empty SFP+ slot on a compatible switch, router or optical transport device until it clicks into place. Connect the single optical fiber between paired transceivers using compatible fiber connectors and ensure the correct orientation for transmit and receive wavelengths. Verify link status using device LEDs or management interfaces and check that transceiver settings and port speed are configured for 10 Gb/s operation. For removal, power down or disable the port if required by the host device, then press the latch and pull the module out gently.

Recommendations

Use single-mode fiber with appropriate link budget calculations for distances approaching 40 km and ensure both ends of the link use complementary BX transceivers with matching wavelengths. Follow equipment manufacturer guidance for supported transceiver models and firmware compatibility, and handle the module by the housing to avoid contamination of the optical interface. Clean fiber connectors before mating and store unused modules with dust caps to protect the optical ports.
