SFP transceiver CBO SFP-1G-LX-20KM 1 Gbit/s 20 km single-mode

The BlueOptics CBO SFP-1G-LX-20KM is a 1 Gbps SFP transceiver module engineered for single-mode fiber links up to 20 km. It offers a compact, hot-pluggable interface for network switches, routers and optical equipment, enabling fiber connectivity for LAN and metro environments. The module supports standard 1 Gigabit Ethernet transport over single-mode fiber and is intended for uplinks, long-distance server connections and fiber backbone links where straightforward installation and reliable optical transmission are required.

Advantages

This SFP transceiver provides a combination of compact design and hot-pluggable convenience that simplifies upgrades and maintenance of network hardware. It uses single-mode optics optimized for distances up to 20 km, ensuring stable 1 Gbps throughput for point-to-point links. The module is compatible with common SFP ports and supports straightforward insertion and removal without powering down equipment, helping to minimize downtime during deployment or replacement.

Suitable for

• Switch-to-switch uplinks in campus and metro networks
• Server-to-switch long-reach connections in data centers
• Fiber backbone links and aggregation points
• Fiber extension for LAN segments and branch offices

Key specifications

• Data rate: 1 Gbps full duplex
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 20 km over single-mode fiber
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Interface: optical LC connector
• Optical wavelength: typical LX multimode wavelength suitable for single-mode long reach

How to use

Insert the SFP module into an empty SFP slot on a compatible switch, router or optical device until it seats firmly. Connect a single-mode fiber cable with LC connectors to the module, observing correct transmit/receive orientation. Configure the network device as required for a 1 Gbps link, verify link status and monitor interface statistics to confirm stable optical power and throughput. Remove the module by releasing any retention latch and pulling straight out while the host device remains powered if hot-swap is supported.

Recommendations

Use certified single-mode fiber with appropriate attenuation characteristics for runs approaching the 20 km limit, and inspect LC connectors for cleanliness before installation. Ensure the host device supports third-party SFP modules and that firmware settings match the intended link parameters to achieve reliable 1 Gbps performance.
