Transceptor SFP+ CBO SFP-10G-ER 10G 40 km

The BlueOptics SFP+ Transceiver CBO SFP-10G-ER 10G 40 km is an optical module for single-mode fiber that supports 10 Gigabit Ethernet links up to 40 kilometres. It uses the hot-pluggable SFP+ form factor and is intended for uplink and long-distance connections in switches, routers and optical fibre backbones. The transceiver provides a stable 10G data rate and is compatible with standard 10G optical ports to extend network links between sites and data centres.

Advantages

This SFP+ module delivers long-reach connectivity over single-mode fiber with a maximum reach of 40 km, enabling link extension without intermediate regeneration. The hot-pluggable SFP+ form factor simplifies installation and replacement without powering down equipment. Built for 10 Gigabit Ethernet, the transceiver ensures a consistent 10G data rate and is compatible with common SFP+ ports used in modern switches and routers. Its optical interface reduces electrical cabling and supports consolidation of fiber infrastructure for inter-site and aggregation links.

Suitable for

• Long-distance uplinks between switches and routers within campus or metro networks
• Inter-site links between buildings and data centre racks up to 40 km apart
• Optical backbone and aggregation links where single-mode fibre is deployed
• Replacement or upgrade of existing 10G SFP+ ports to extend reach

Key specifications

• Data rate: 10 Gigabit Ethernet (10G)
• Fiber type: Single-mode fiber (SMF)
• Maximum reach: up to 40 km
• Form factor: SFP+ hot-pluggable
• Optical interface: long-range ER class transmission
• Typical mounting: 1x SFP+ slot in compatible network devices

How to use

Power off the host device if recommended by the equipment vendor, insert the SFP+ transceiver into an available SFP+ port until it seats firmly, and connect single-mode fiber patch cables with the appropriate connectors. Verify link status and configuration in the host switch or router management interface and configure speed/duplex or auto-negotiation settings if required. For hot-swap capable systems, the module can be inserted or removed while the host remains powered, following the vendor’s hot-plug guidelines.

Recommendations

Use single-mode fiber with appropriate attenuators or dispersion management for long links, keep connectors clean and use dust caps when not connected, and validate optical power and link budget for distances approaching 40 km to ensure reliable operation.
