## Summary description

CBO SFP-10G-BX-D-40KM-DL-BO is an SFP+ optical transceiver module supporting 10 Gbit/s data rate for single-mode fiber with LC connector. Designed for bi-directional (downlink) transmission over distances up to 40 km, it enables high-speed uplink/downlink links in data centers, carrier networks and enterprise backbone connections, offering compact hot-pluggable installation and interoperability with compatible SFP+ ports.

## Long description

The CBO SFP-10G-BX-D-40KM-DL-BO is a compact SFP+ optical transceiver designed for 10 Gbit/s single-mode fiber links using an LC connector. Engineered for bi-directional (downlink) transmission over distances up to 40 km, this module enables high-speed point-to-point connectivity in data centers, carrier networks and enterprise backbones. Its hot-pluggable form factor supports easy installation and replacement in compatible SFP+ ports and helps maintain continuous network operation without powering down equipment.
Advantages
This SFP+ module supports full 10 Gbit/s throughput on single-mode fiber with bi-directional transmission, reducing the number of fibers required for duplex links. The LC connector and compact SFP+ footprint enable high-density port deployment. Hot-pluggable design simplifies maintenance and upgrades, while compatibility with standard SFP+ interfaces ensures interoperability with a wide range of network switches and routers. The module is optimized for long-reach links up to 40 km, making it suitable for metropolitan and campus interconnects.
Suitable for
10 Gbit/s uplink and downlink connections between switches and routers
Long-distance single-mode fiber links up to 40 km within carrier or campus networks
Data center inter-rack and inter-site connectivity requiring bi-directional transmission
Enterprise backbone and metropolitan area network links where fiber count reduction is desired
Key specifications
Data rate: 10 Gbit/s
Fiber type: single-mode
Connector: LC duplex (bi-directional operation using a single fiber pair)
Transmission distance: up to 40 km (single-mode)
Transmission mode: bi-directional (downlink)
Form factor: SFP+ hot-pluggable
How to use
Insert the module into a compatible SFP+ port on a switch or router until it clicks into place, then connect single-mode fiber with LC connectors. Ensure the correct orientation for bi-directional links so that transmit and receive fibers are matched between endpoints. After physical installation, verify link status and configure interface parameters on connected devices as required by your network settings. For removal, power down the port if recommended by the equipment vendor, then release the module using the latch and pull it straight out.
Usage recommendations
Use single-mode fiber with appropriate attenuation and test links after installation to confirm signal quality. Keep dust caps on unused ports, handle the LC connectors carefully, and follow ESD precautions when installing or removing the transceiver to maintain reliable operation over the rated 40 km reach.
