SFP+ optical transceiver CBO SFP-10G-BX-D-40KM-SP-BO 10 Gbps, single-fiber, LC, 40 km

The CBO SFP-10G-BX-D-40KM-SP-BO is a single-fiber SFP+ optical transceiver module that supports 10 Gbps data transmission over a single strand of single-mode fiber with an LC connector. Engineered for integration into switches, routers and media converters, this module implements bidirectional communication on a single fiber using wavelength division, enabling 40 km link distances without the need for a second fiber strand. The compact SFP+ form factor is compatible with standard 10G ports and is intended for long-distance uplinks and point-to-point 10G connections in campus, metro and carrier networks.

Advantages

The transceiver delivers 10 Gbps capacity with single-fiber operation, reducing fiber cabling requirements while maintaining full-duplex communication through wavelength division. Its LC interface and SFP+ form factor provide broad compatibility with common networking equipment from switches and routers to media converters. The 40 km reach supports longer metro and access links without additional amplification or regeneration in many deployments. The module is designed for straightforward hot-pluggable installation and low power consumption appropriate for dense 10G deployments.

Suitable for

• 10G single-fiber uplinks between switches in campus and data center edge
• Point-to-point 10G connections across metro or regional links up to 40 km
• Integration into routers and media converters requiring LC single-mode interfaces
• Network upgrades where fiber availability is limited and single-fiber links reduce cabling

Key specifications

• Data rate: 10 Gbps
• Fiber type: Single-mode fiber (single-fiber bidirectional operation)
• Connector: LC duplex (single-fiber operation uses one LC port)
• Reach: Up to 40 km over single-mode fiber
• Form factor: SFP+ (hot-pluggable)
• Transmission method: Bidirectional on single fiber using wavelength division
• Typical application: Uplink and point-to-point 10G links

How to use

Install the module into a compatible SFP+ slot on a switch, router or media converter while the host device is powered according to the equipment manufacturer’s instructions. Connect a single strand of single-mode fiber terminated with an LC connector; ensure the transmitting and receiving wavelengths are matched for the paired transceiver (directional pairing is required). After insertion, verify link status and port configuration through the host device management interface and adjust port speed/duplex settings if necessary. For best results, observe proper fiber handling and cleaning procedures to prevent connector contamination and signal loss.

Recommendations

Use matched transceiver pairs for correct wavelength directionality and verify compatibility with the host device’s SFP+ port. Keep connectors clean and follow the switch or router vendor’s guidance for hot-plug handling and firmware compatibility. For links approaching the maximum distance, verify optical power budget and consider attenuation from connectors and splices.
