SFP+ transceiver CBO SFP-10G-BX-U-40KM-EE-BO 10 Gbps LC single-fiber 40 km

CBO SFP-10G-BX-U-40KM-EE-BO is an SFP+ optical transceiver module that supports 10 Gbit/s data rate over a single-fiber bidirectional link. With an LC connector and a reach of up to 40 km, this module is intended for long-reach uplink and interconnect applications in switches and routers. The single-fiber bidirectional design reduces fiber cabling by using different wavelengths for transmit and receive, making it suitable for constrained fiber environments and carrier-access or metro links.

Advantages

The module provides 10 Gbps throughput in a compact SFP+ form factor, enabling high-density port deployments. Its single-fiber bidirectional operation halves fiber count compared with parallel-fiber solutions and supports long-reach links up to 40 km. The LC interface ensures compatibility with standard fiber patching, and the module is intended for use in typical 10 Gigabit Ethernet or compatible telecom environments where standard SFP+ electrical and optical interfaces are required.

Suitable for

• Long-reach uplinks between switches and routers in data centers and enterprise networks
• Metro and carrier access links where fiber count must be minimized
• Upgrading 1/10G sites to single-fiber 10G connections
• High-density aggregation panels and SFP+ port installations

Key specifications

• Data rate: 10 Gbit/s
• Form factor: SFP+
• Connector type: LC
• Fiber type: single-fiber, bidirectional operation (wavelength multiplexing)
• Maximum link length: up to 40 km (single-mode fiber)
• Application: 10 Gigabit Ethernet and compatible telecom interfaces

How to use

Insert the SFP+ transceiver into an appropriate SFP+ slot on a switch, router or fiber transceiver cage while the host device is powered according to the vendor's hot-plug guidance. Connect a single-mode LC patch cable to the module and ensure the opposite-end module uses the complementary wavelength (transmit/receive pair) for bidirectional operation. Verify link status and speed through the host device management interface and follow the equipment manufacturer's procedures for optical power budgeting and link diagnostics.

Recommendations

Confirm compatibility with the host device and firmware before deployment, check optical power budget and fiber attenuation for the planned 40 km span, and use clean LC connectors and appropriate dust caps when the module is not connected to prevent contamination and signal loss.
