SFP+ optical transceiver CBO SFP-10G-ER 10G 40km

CBO SFP-10G-ER 10G 40km is an SFP+ optical transceiver module from BlueOptics that delivers 10 Gigabit Ethernet over single-mode fiber for links up to 40 km. The small form-factor pluggable module is designed to fit standard SFP+ ports and provides a reliable physical layer interface for long-distance uplinks, inter-switch connections and metro/backbone segments in data center and telecommunications environments.

Advantages

The module supports 10G Ethernet data rates and 40 km reach, enabling long-distance connectivity without additional regeneration. Its SFP+ form factor provides hot-pluggable installation and compatibility with a wide range of switches and routers that accept SFP+ optics. The product offers consistent optical performance for backbone links and reduces the need for multiple intermediate devices when extending network segments across campus, metropolitan or carrier networks.

Suitable for

• Data center uplinks and inter-switch links
• Carrier and metro network long-haul segments
• Campus backbone connections between buildings
• High-speed server to switch connections over single-mode fiber

Key specifications

• Data rate: 10 Gigabit Ethernet
• Maximum reach: up to 40 km over single-mode fiber
• Form factor: SFP+ (small form-factor pluggable)
• Wavelength: long-range optical wavelength suitable for extended reach (ER)
• Interface: duplex LC connector
• Hot-pluggable support: yes

How to use

Install the CBO SFP-10G-ER 10G 40km by inserting the module into an available SFP+ port on a compatible switch or router until it locks. Attach single-mode fiber with LC duplex connectors and verify correct transmit/receive orientation. After physical installation, check the device management interface to confirm link status and negotiate the 10G connection. Follow your network equipment vendor guidance if the host device requires specific configuration or optical support settings.

Recommendations

Use certified single-mode fiber and maintain clean LC connectors to ensure optimal performance. Verify compatibility with the host device and confirm that the link budget (fiber attenuation and any connectors/splices) supports the intended 40 km span. For mixed-vendor environments, test the module in the target hardware before deployment to ensure reliable operation.
