SFP-10G-ER 10G Ethernet transceiver CBO — single‑mode 40 km

The BlueOptics SFP-10G-ER 10G Ethernet transceiver CBO is a hot-pluggable SFP+ module for 10 Gigabit Ethernet links over single-mode fiber. Engineered for long-reach connections up to 40 km, this compact transceiver provides a standard LC optical interface for installation in routers, switches and optical multiplexing equipment. The module supports straightforward insertion and removal to simplify upgrades and reduce service interruptions during maintenance or replacement.

Advantages

This single-mode transceiver delivers stable 10 Gbps connectivity over extended distances while maintaining a small form factor suitable for dense network equipment. Hot-pluggable capability enables on-the-fly replacement without powering down connected devices. The module is compatible with standard SFP+ ports and supports reliable link performance for data centre uplinks and metropolitan network segments.

Suitable for

• Long-distance 10 Gigabit Ethernet links over single-mode fiber
• Data centre switch and router uplinks
• Metro and campus backbone connections
• Optical network equipment requiring SFP+ form factor

Key specifications

• Data rate: 10 Gbps (SFP+)
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 40 km (dependent on fiber and link budget)
• Connector: LC duplex optical interface
• Form factor: SFP+ hot-pluggable transceiver
• Transmission: optical, 10G Ethernet compliant

How to use

Insert the SFP-10G-ER module into an empty SFP+ port on a compatible switch, router or optical device until it clicks into place. Connect a single-mode LC duplex fiber patch cable between transceivers at both ends of the link, ensuring correct polarity. Configure the network device to enable the 10 Gbps interface as required by your operating system or switch firmware. When replacing the module, remove it while the device remains powered if supported by the equipment, then install the new transceiver and verify link status.

Recommendations

Use certified single-mode fiber with appropriate attenuation and clean LC connectors to achieve the rated 40 km reach. Verify link budget and disable incompatible auto-negotiation settings if required by your network hardware. Keep dust caps on the optical ports when the transceiver is not in use and consult equipment compatibility lists for confirmed support of third-party SFP+ modules.
