SFP+-module CBO SFP-10G-BX-D-40KM-LC-BO 10 Gbit/s LC single-fibre-duplex, 40 km

CBO SFP-10G-BX-D-40KM-LC-BO is an SFP+ transceiver module that supports 10 Gbit/s data transmission over a single-fiber bidirectional (BX) link with an LC connector. The module is designed for long-distance optical connections up to 40 km, enabling high-speed uplinks between switches, routers and other optical network equipment. Its single-fiber duplex design reduces fibre usage by allowing transmit and receive signals on one strand, while maintaining compatibility with standard SFP+ ports and LC fiber cabling.

Advantages

The module provides a 10 Gbit/s data rate with BX single-fiber operation to extend network reach without requiring a second fiber strand. Its LC connector ensures compatibility with common fiber patch panels and transceivers. The compact SFP+ form factor allows easy hot-plug installation into SFP+ ports of network devices and supports high-density deployments in racks and chassis. Built for long-reach metro and access links, the transceiver balances performance and fibre efficiency for cost-conscious infrastructure planning.

Suitable for

• Long-distance uplinks between aggregation switches and core equipment
• Metro and access networks where fibre count is limited
• Data center interconnects requiring 10 Gbit/s links over single-fibre runs
• Upgrading existing fiber infrastructure to higher speeds without laying additional fiber

Key specifications

• Data rate: 10 Gbit/s
• Reach: up to 40 km over single-mode fiber
• Connector type: LC
• Fiber type: single-mode, bidirectional (BX) single-fiber duplex
• Form factor: SFP+
• Transmission method: bidirectional optical (simultaneous transmit and receive on one fiber using different wavelengths)

How to use

Install the SFP+ module into an available SFP+ port on your switch, router or optical device until it latches. Connect a single-mode LC patch cable between this module and a compatible BX transceiver at the remote end, ensuring the correct polarity for transmit and receive. Configure the network device to enable the 10 Gbit/s port if required by the operating system or switch firmware. Verify link status and optical diagnostics through the device management interface and monitor signal parameters during initial operation.

Recommendations

For reliable performance, use single-mode fiber rated for long-reach links and maintain clean LC connectors. When deploying in metro or access networks, pair the module with a complementary BX transceiver at the far end that matches wavelengths and reach. Check equipment compatibility with SFP+ ports and update device firmware if necessary to ensure link negotiation at 10 Gbit/s.
