CBO SFP+ module SFP-10G-BX-D-40KM-QL-BO 10 Gbit/s LC single-fiber bidirectional, 40 km

CBO SFP+ SFP-10G-BX-D-40KM-QL-BO is a 10 Gbit/s LC transceiver module engineered for single-fiber bidirectional (BX-D) links up to 40 km. The module fits SFP+ ports on switches and routers and enables high-speed fiber connections for backbone extensions, datacenter uplinks and metro links. Its compact hot-swappable SFP+ form factor and LC interface support convenient installation and replacement without powering down equipment.

Advantages

The module provides 10 Gbit/s full-rate data throughput over a single fibre pair, reducing fiber cabling requirements compared to separate transmit and receive fibers. Its single-fiber bidirectional operation simplifies link planning and conserves fiber infrastructure. The hot-swappable SFP+ form factor allows fast maintenance and upgrades. Designed for interoperability with standard SFP+ cages and LC connectors, it supports long-reach links up to 40 km for flexible network design.

Suitable for

• Datacenter uplinks between aggregation and core switches
• Fiber backbone extensions in enterprise networks
• Campus and metro links where fiber count is limited
• Service provider access and aggregation segments

Key specifications

• Data rate: 10 Gbit/s
• Interface: LC single-fiber bidirectional (BX-D)
• Maximum link distance: up to 40 km over single-mode fiber
• Form factor: SFP+ hot-swappable transceiver
• Transmission: single-fiber TX and RX on different wavelengths

How to use

Install the module into an available SFP+ port on a compatible switch or router until it clicks into place. Connect a single-mode LC patch cable designed for bidirectional operation between modules at each link end, ensuring correct orientation of LC connectors. Verify link status and speed in the host device management interface and confirm that any required port settings (such as transceiver auto-negotiation or speed settings) are configured. For hot-swap replacement, remove the module using the device's recommended procedure and insert the replacement while monitoring system link states.

Recommendations

Use single-mode fiber rated for 40 km links and LC connectors optimized for bidirectional transceivers. Maintain clean connector endfaces and follow ESD precautions when handling the transceiver. Check device compatibility lists or use vendor-neutral settings when interoperability issues arise, and monitor optical power and error statistics in the host device to validate link performance.
