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

CBO SFP-10G-BX-D-40KM-CI-BO is an SFP+ optical transceiver that supports a 10 Gbps data rate and uses an LC connector for single-fiber bidirectional transmission. It implements BX-D operation to transmit and receive over a single fiber pair, enabling links up to 40 km. Designed for 10G Ethernet and Fibre Channel deployments, this transceiver is suitable for long-reach uplinks, metro connections and scenarios where fiber count minimization is important.

Advantages

The module provides 10 Gbps throughput in a small SFP+ form factor, reducing space in equipment bays while maintaining high performance. Single-fiber bidirectional operation lowers fiber usage compared with dual-fiber transceivers, simplifying cabling and reducing infrastructure costs. LC interface compatibility ensures broad interoperability with standard fiber patch panels and adapters. Operating range up to 40 km makes it suitable for campus, metro and carrier links where extended reach is required.

Suitable for

• 10G Ethernet uplinks between switches and routers
• Fibre Channel storage area network (SAN) links
• Metro and campus interconnections over single-fiber spans
• Carrier aggregation and long-reach access links

Key specifications

• Data rate: 10 Gbps
• Form factor: SFP+
• Connector type: LC
• Fiber type: single-fiber bidirectional (BX-D)
• Maximum reach: up to 40 km
• Application: 10G Ethernet, Fibre Channel

How to use

Install the transceiver into an SFP+ slot of a compatible switch, router or media converter, ensuring the device supports single-fiber bidirectional modules. Connect the LC patch cable to the module and to the corresponding single-fiber port on the remote transceiver, observing correct Tx/Rx orientation for BX-D operation. Allow the host device to detect and negotiate the link speed; verify link status and performance using the management interface or diagnostics. Follow standard ESD precautions when handling the module and keep protective caps on connectors when not in use.

Recommendations

Use quality single-mode fiber and LC patch cords rated for the intended distance to achieve reliable 40 km links. Validate compatibility with the host equipment and, if necessary, consult link budget calculations to confirm signal margins. Avoid bending or stressing fiber connectors, and perform periodic optical power and BER checks in critical links.
