SFP+ transceiver CBO SFP-10G-BX-U-40KM-NG-BO 10 Gbit/s, LC, single-mode, up to 40 km

The CBO SFP-10G-BX-U-40KM-NG-BO is a BlueOptics SFP+ optical transceiver module that supports a 10 Gbit/s data rate and uses an LC connector for single-mode fiber. Engineered for long-distance links, this BX (bi-directional) module enables data transmission and reception over a single fiber strand with separate wavelengths, enabling link spans up to 40 km. It is compatible with 10G Ethernet and Fibre Channel ports in switches, routers and media converters and is intended for backbone and metro deployments where space-efficient, hot-pluggable optics are required.

Advantages

This SFP+ transceiver provides a compact, hot-pluggable solution for high-speed single-mode links with bi-directional transmission, reducing fiber cabling by using one strand per link. The module supports a 10 Gbit/s data rate, LC duplex-compatible interface, and long-reach operation up to 40 km, making it suitable for extended network segments. Designed for interoperability with standard SFP+ cages and sockets, it offers predictable optical performance for 10G Ethernet and Fibre Channel applications.

Suitable for

• 10G Ethernet uplinks in data center and campus networks
• Fibre Channel links in SAN environments
• Point-to-point metro and backbone connections up to 40 km
• Interoperable use in switches, routers and media converters with SFP+ slots

Key specifications

• Form factor: SFP+ hot-pluggable module
• Data rate: 10 Gbit/s
• Fiber type: single-mode
• Connector: LC
• Interface type: BX bi-directional (separate wavelengths for TX and RX over single fiber)
• Maximum link distance: up to 40 km (depending on fiber type and link budget)
• Application: 10G Ethernet, Fibre Channel

How to use

Install the transceiver into an available SFP+ slot on a compatible switch, router or media converter while the device is powered according to the host vendor's instructions. Connect single-mode LC fiber patch cords, ensuring the correct BX pairing between upstream and downstream ports so that transmit and receive wavelengths align. Verify link status via the host device management interface and monitor optical power and error counters as needed. For safety, follow standard fiber handling practices and avoid looking into fiber ends.

Recommendations

Use this module with single-mode fiber and LC patch cords rated for long-reach links; verify host compatibility for SFP+ modules and BX operation. When deploying over maximum distances, check the link budget, fiber attenuation and any inline connectors or splices to ensure reliable performance.
