SFP+ transceiver CBO SFP-10G-BX-D-40KM-DE-BO 10 Gbit/s single‑mode LC bidirectional 40 km

CBO SFP-10G-BX-D-40KM-DE-BO is an SFP+ optical transceiver designed for 10 Gbit/s data transmission over single-mode fiber with an LC connector. The module supports bidirectional (BX-D) operation, enabling separate transmit and receive wavelengths to carry duplex traffic over a single fiber pair. It is intended for installation in switches, routers and telecommunications equipment that require compact, hot-swappable 10G uplinks and long-reach connectivity up to 40 km.

Advantages

The transceiver provides 10 Gbit/s line-rate performance with low power consumption in an SFP+ form factor suitable for dense installation. Bidirectional BX-D design reduces fiber infrastructure needs by using one fiber pair for duplex links. The LC connector ensures compatibility with standard single-mode fiber cabling, while the module's hot-swappable capability allows replacement or upgrades without powering down equipment. The optical design supports reliable links to distances of up to 40 km when used with appropriate single-mode fiber and network equipment.

Suitable for

• 10G uplinks between access switches and aggregation/core switches over single-mode fiber
• Long-reach point-to-point connections in data center and campus networks
• Telecom and service provider interfaces requiring compact, hot-swappable optics
• Router and switch expansion ports where BX bidirectional operation reduces fiber cabling

Key specifications

• Data rate: 10 Gbit/s
• Fiber type: single-mode
• Connector: LC duplex (bidirectional over single fiber pair)
• Transmission mode: bidirectional (BX-D), separate TX/RX wavelengths
• Maximum reach: up to 40 km (over appropriate single-mode fiber)
• Form factor: SFP+
• Hot-swappable: yes

How to use

Insert the SFP+ transceiver into a compatible SFP+ slot on your switch, router or optical device, ensuring the module is fully seated and latched. Connect single-mode fiber using LC connectors, observing correct transmit/receive orientation for bidirectional operation. After physical installation, verify the link status and speed via the host equipment's management interfaces and monitor for correct optical levels. Use appropriate fiber patching and cleanliness practices to avoid signal loss; clean LC connectors before mating if necessary.

Recommendations

Use single-mode fiber with appropriate attenuation and dispersion characteristics for 40 km links, and ensure compatible wavelength support on both ends of the connection. Confirm that your network equipment supports SFP+ optics and bidirectional BX-D modules. Maintain connector cleanliness and secure fiber routing to avoid bend losses; consult equipment documentation for any vendor-specific configuration or compatibility notes.
