SFP+ transceiver CBO SFP-10G-BX-U-40KM-IT-BO 10 Gbit/s LC single‑fiber 40 km

CBO SFP-10G-BX-U-40KM-IT-BO is an SFP+ optical transceiver module supporting 10 Gbit/s data rate over a single fiber with an LC connector and a transmission reach of up to 40 km. Designed for service provider and enterprise networks, this module implements single-fiber bidirectional transmission suitable for long-distance uplinks and metro/DWDM edge applications. The compact SFP+ form factor enables hot-pluggable installation in compatible switches, routers and optical devices and provides a practical option for extending 10 Gigabit Ethernet links without changing existing fiber infrastructure.

Advantages

The transceiver delivers 10 Gbit/s performance in a small SFP+ package while using a single fiber for transmit and receive channels, which reduces fiber cabling requirements in point-to-point links. The LC connector and industry-standard electrical interface make the module interoperable with a wide range of network equipment. Support for up to 40 km reach enables long-distance uplinks and interbuilding connections. Built for straightforward plug-and-play deployment, it minimizes configuration effort and fits common carrier-grade and enterprise environments.

Suitable for

• Long-distance 10 Gigabit Ethernet uplinks between buildings or sites
• Metro and DWDM edge connections where single-fiber operation is required
• Service provider networks requiring compact, hot-pluggable optics
• Enterprise backbone links and data center interconnects over single fiber

Key specifications

• Data rate: 10 Gbit/s
• Form factor: SFP+ (hot-pluggable)
• Fiber type: single-fiber bidirectional
• Connector: LC duplex (single-fiber operation with appropriate adapter)
• Maximum reach: up to 40 km (depending on fiber quality and link budget)
• Application: 10 Gigabit Ethernet, DWDM/metro edge, long-reach uplinks

How to use

Install the SFP-10G-BX-U-40KM-IT-BO into a compatible SFP+ port on your switch or router while the device is powered on or off, observing the equipment manufacturer’s hot-swap procedures. Connect the single-fiber LC cable or appropriate pass-through adapter so that transmit and receive channels are matched to the remote module. Configure the host port for 10 Gbit/s operation if necessary; most devices will auto-negotiate with the module. Verify link status and signal levels in the host device’s management interface after installation to confirm a stable connection.

Recommendations

Use single-mode fiber rated for long-distance transmission and confirm end-to-end link budget when planning 40 km links. Ensure compatible wavelength and direction when pairing with the remote transceiver (BX-U type) and follow manufacturer guidance for optical power and temperature ranges to maintain reliable operation.
