SFP 1G LX Fiber Optic Transceiver CBO SFP-1G-LX-20KM — 1 Gbps, single-mode, up to 20 km

CBO SFP-1G-LX-20KM is a compact SFP-format fiber optic transceiver that supports 1 Gbps data rate over single-mode fiber for links up to 20 km. The module is designed for insertion into standard SFP slots of network switches, routers and media converters, providing a hot-swappable interface for long-distance connectivity. It enables extension of fiber links, creation of uplinks between network devices and connection of geographically dispersed equipment in enterprise networks, service provider infrastructures and data center environments.

Advantages

The transceiver offers stable 1 Gbps performance with low power consumption in a small, hot-swappable form factor compatible with standard SFP ports. Single-mode optics and a specified reach of up to 20 km allow for long-distance links without intermediate repeaters. The module supports industry-standard electrical and optical interfaces, which simplifies replacement or upgrade of existing fiber connections while maintaining interoperability with common network hardware.

Suitable for

• Establishing uplinks between switches and routers over single-mode fiber
• Connecting remote network nodes across campus or metropolitan distances
• Extending fiber segments in data centers and telecom rooms
• Replacing or upgrading existing SFP ports for long-reach links

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1 Gbps (gigabit Ethernet/optical)
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 20 km over single-mode fiber
• Wavelength: typical long‑reach optical wavelength for LX-class modules
• Connector type: LC duplex optical connector
• Hot-swappable: yes
• Power consumption: low (suitable for dense deployments)

How to use

Insert the CBO SFP-1G-LX-20KM into a compatible SFP slot while the host device is powered on or off; the hot-swappable design permits replacement without shutting down the system. Connect an LC-terminated single-mode fiber patch cord to the module's duplex connector and ensure proper transmit/receive orientation. Configure the host interface for 1 Gbps operation if manual settings are required, and verify link status through the device management interface or front-panel indicators. Observe standard handling precautions for optical transceivers to avoid damaging the fiber interface.

Recommendations

Use single-mode fiber of appropriate grade and LC duplex connectors to achieve the specified 20 km reach. Clean connector end-faces before mating and verify link parameters after installation. For mixed-vendor environments, confirm compatibility with the host device and consider enabling auto-negotiation or configuring fixed speed/duplex settings as recommended by the network equipment vendor.
