SFP Transceiver CBO SFP-1G-LX-20KM 1.25Gbps 20 km Single‑mode LC

The CBO SFP-1G-LX-20KM is a 1.25Gbps SFP optical transceiver for single-mode fiber links up to 20 km. It fits standard SFP cages and supports 1G Ethernet interfaces with an LC duplex connector, enabling reliable long-reach connections between switches, routers and optical patch panels. The module is intended for deployment in campus networks, data center uplinks and telecom environments requiring stable 20 km single-mode transport.

Advantages

The transceiver offers 1.25Gbps data rate compatibility with widely used Gigabit Ethernet equipment and a single-mode design optimized for distances up to 20 km. Its LC connector and standard SFP form factor ensure broad interoperability with network switches and routers. Low power consumption and plug-and-play operation reduce installation complexity while providing a compact footprint for dense port configurations.

Suitable for

• Fiber uplinks between switches and routers in campus and enterprise networks
• Data center interconnects and uplink ports requiring single-mode reach
• Telecom access links and point-to-point fiber runs up to 20 km
• Optical patch panel terminations and network equipment with SFP slots

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1.25 Gbps (Gigabit Ethernet compatible)
• Fiber type: single-mode fiber
• Maximum reach: up to 20 km
• Connector type: LC duplex
• Wavelength: typical long‑reach wavelength for 1G LX class optics
• Hot-pluggable with standard SFP cage compatibility

How to use

Insert the SFP-1G-LX-20KM transceiver into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect single-mode LC fiber patch cables to the module’s LC duplex connector, observing transmit/receive orientation. Ensure the remote end is equipped with a matching single-mode SFP module and that both devices are configured for 1G operation if manual configuration is required. After installation, verify link status and optical levels via the host device management interface.

Recommendations

Use clean, industry-standard single-mode LC patch cables and avoid bending the fiber beyond recommended bend radii. Confirm compatibility with the host device’s supported SFP specifications and monitor optical power and link stability after deployment to ensure the expected 20 km performance.
