SFP-10G-ER Fiber Optic Transceiver CBO — 10G, long-reach (up to 40 km)

The CBO SFP-10G-ER Fiber Optic Transceiver CBO is a 10 Gigabit SFP+ module engineered for long-reach single-mode fiber links up to 40 km. It provides a compact, hot-pluggable interface for 10G Ethernet and Fibre Channel equipment, enabling extension of high-speed connections between switches, routers and servers. The transceiver supports standard optical wavelengths and is suitable for backbone, campus and metro network segments that require reliable optical transmission over single-mode fiber.

Advantages

This SFP+ transceiver delivers 10 Gbps throughput with long-reach capability up to 40 km, allowing cost-effective extension of network links without additional active equipment. Its compact SFP+ form factor supports hot-plug installation and interoperability with a wide range of 10G ports. The module is designed for single-mode fiber, providing stable optical performance for backbone and metro scenarios and reducing the need for complex setup or frequent maintenance.

Suitable for

• Extending 10G Ethernet links between switches over single-mode fiber
• Interconnecting routers and core switches in campus or metro networks
• Fibre Channel connections in storage area networks requiring long reach
• Replacement or spare module for 10G SFP+ ports in data centers

Key specifications

• Data rate: 10 Gbps (SFP+ compliant)
• Reach: up to 40 km over single-mode fiber
• Form factor: SFP+ (hot-pluggable)
• Fiber type: single-mode
• Typical wavelength: compatible with long-reach optical windows for single-mode transmission
• Interface: LC duplex optical connector

How to use

Install the SFP-10G-ER module into a compatible SFP+ port on your switch, router or host adapter while the device is powered on or off as the module supports hot-swapping. Connect LC duplex single-mode fiber cables between devices, ensuring correct transmit/receive pairing. Verify link negotiation and 10G operation via the network device management interface and monitor optical levels to confirm proper signal margins. For initial deployment, check compatibility with your hardware and, if required, update firmware or transceiver settings according to the equipment vendor guidance.

Recommendations

Use high-quality single-mode fiber and clean LC connectors to maintain optical performance. Avoid bending fibers beyond specified bend radius and protect transceiver ports from dust when not in use. Confirm transceiver compatibility with the host device and consult optical power budget requirements for links approaching the 40 km limit.
