Transceiver CBO SFP-10G-ER 10G 40km — CBO SFP module for 10 Gigabit Ethernet, single-mode up to 40 km

The Transceiver CBO SFP-10G-ER 10G 40km is a 10 Gigabit Ethernet SFP module for single-mode fiber links supporting distances up to 40 km. It offers a compact, hot-pluggable form factor for deployment in compatible switches, routers and optical equipment, enabling long-reach uplinks and interconnects for data centers, metro networks and enterprise backbones. The module implements standard SFP+ electrical and optical interfaces for straightforward integration into existing fiber infrastructures.

Advantages

This SFP module delivers 10 Gbps bandwidth over single-mode fiber with a rated reach of up to 40 km, allowing long-distance connectivity without intermediate regeneration. The compact SFP form factor reduces space requirements in chassis-based systems and supports hot-swap replacement to simplify maintenance. Compliance with standard interface specifications ensures interoperability with a wide range of network equipment that accepts SFP/SFP+ optical transceivers.

Suitable for

• Long-distance 10 Gigabit uplinks between switches and routers
• Data center interconnects and fiber-based aggregation links
• Metro and carrier Ethernet segments requiring single-mode fiber
• Enterprise backbone links and campus connectivity over fiber

Key specifications

• Data rate: 10 Gigabit Ethernet (10 Gbps)
• Fiber type: single-mode fiber (SMF)
• Max reach: up to 40 km (over single-mode fiber, depends on fiber and link conditions)
• Form factor: SFP/SFP+ hot-pluggable transceiver
• Interface: standard SFP electrical interface and optical LC connector
• Optical wavelength: suitable for long-reach single-mode transmission (ER class)

How to use

Insert the transceiver into an SFP/SFP+ slot of a compatible switch, router or optical device while the host port is powered off or following the equipment manufacturer’s hot-plug guidelines. Connect the single-mode fiber cable with LC connectors to the transceiver’s optical port, ensuring proper polarity and secure connections. After installation, verify link status and operating parameters via the host device management interface and monitor optical power and error counters to confirm stable operation.

Recommendations

Use verified single-mode fiber and appropriate LC connectors, maintain correct fiber polarity, and ensure patch panels and splices meet loss budget requirements for 40 km links. Check device documentation for supported transceiver types and firmware compatibility before deployment. For long-distance links, validate optical power margins and consider attenuation, connector loss and splicing when planning the link.
