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

The SFP+ transceiver CBO SFP-10G-ER 10G Ethernet, single‑mode 40 km is a hot-pluggable optical module designed to provide reliable 10 Gigabit Ethernet links over single‑mode fiber. Intended for use in switches, routers and optical transmission equipment, this SFP+ transceiver supports long-distance connections up to 40 km, making it suitable for metro and inter-building links. The compact form factor enables tool-free insertion and replacement without powering down connected equipment.

Advantages

This SFP+ module delivers 10G Ethernet performance over single‑mode fiber with a 40 km reach, enabling cost-effective extension of network segments. Its hot-pluggable design reduces service interruptions during upgrades or maintenance. The module is compatible with standard SFP+ ports and offers stable optical performance for high-throughput applications, while the small form factor conserves space in network racks and optical chassis.

Suitable for

• Long-distance 10G connectivity between data centers and campus buildings
• Metro aggregation links and carrier access
• Fiber backbone extensions within enterprise networks
• Upgrading switches or routers to 10G single‑mode links

Key specifications

• Interface: SFP+ (hot-pluggable)
• Data rate: 10 Gbps
• Fiber type: single‑mode fiber (SMF)
• Maximum reach: up to 40 km over single‑mode fiber
• Wavelength: compatible with long‑reach 10G optics (typical ER band)
• Connector: LC duplex
• Typical applications: metro, long‑distance and backbone links

How to use

Install the SFP+ transceiver into a compatible SFP+ port on a switch, router or optical device while the host remains powered if the system supports hot‑swap. Ensure the LC duplex connectors are clean and properly keyed before mating with single‑mode patch cords. After insertion, confirm link establishment and verify operational parameters through the device management interface. For removal, follow the host equipment instructions for safe hot‑unplug procedures if available.

Recommendations

Use single‑mode fiber with appropriate attenuation and quality for distances up to 40 km, and verify transceiver compatibility with the host device. Keep fiber connectors clean and use dust caps when the module is not connected. Monitor optical receive/transmit levels and device logs to ensure reliable long‑distance operation.
