SFP-transceiver CBO SFP-1G-LX-20KM 1G 20 km singlemode vezel

CBO SFP-1G-LX-20KM is an SFP optical transceiver module that supports 1 Gbps data transmission over single-mode fiber with a typical reach of up to 20 km. The module fits standard SFP slots used in switches, routers and other network equipment and uses an LC connector for the optical interface. It is intended for uplink ports and long-distance point-to-point fiber links where industry-standard form factor and compatibility are required.

Advantages

The transceiver offers a compact SFP form factor compatible with a wide range of network devices and supports a 1 Gbps data rate suitable for gigabit Ethernet and related services. With single-mode fiber support and a maximum reach of up to 20 km, it enables longer distance links without active optical amplification. The LC connector and standard electrical/optical interface simplify installation and interoperability with other optical components.

Suitable for

• Gigabit Ethernet uplinks between switches and routers
• Long-distance single-mode fiber point-to-point links up to 20 km
• Optical ports in data center and enterprise network equipment
• Replacement or upgrade of SFP ports for extended reach

Key specifications

• Data rate: 1 Gbps (gigabit)
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 20 km
• Connector type: LC duplex
• Form factor: SFP (small form-factor pluggable)
• Application: 1000BASE-LX compatible optical link

How to use

Insert the module into a compatible SFP slot on a switch, router or optical device with the module's latch oriented according to the equipment's instructions. Connect single-mode fiber cables with LC connectors to the module's optical port, ensuring correct transmit/receive pairing. After physical installation, verify link status and configure the network interface according to the device's management interface. Observe device LED indicators and management logs to confirm an active 1 Gbps link.

Recommendations

Use single-mode fiber of appropriate attenuation and quality for distances approaching 20 km. Avoid bending or stressing fiber around the LC connector, keep connectors clean and use dust caps when ports are unused. Verify compatibility with the host device and consult the equipment vendor for any required firmware or configuration changes before deployment.
