SFP transceiver CBO SFP-1G-LX-20KM for 1G fibre link, single‑mode, up to 20 km

Compact SFP transceiver CBO SFP-1G-LX-20KM provides a hot-pluggable optical interface for 1 Gbps fibre links. Designed for single-mode operation, the module supports transmission distances up to 20 km and fits standard SFP ports on switches, routers and other network equipment. The transceiver is intended for extending metropolitan or campus connections, long-distance uplinks and for quick replacement of defective optical modules to restore reliable connectivity.

Advantages

The module offers a small form factor compatible with SFP ports and supports hot swapping to minimize downtime during maintenance. Single-mode optics enable stable 1 Gbps throughput over longer distances up to 20 km, while industry-standard electrical and optical interfaces ensure broad interoperability with networking equipment. Low power consumption and a robust design contribute to continuous operation in rack-mounted and distributed environments.

Suitable for

• 1 Gbps uplinks between switches in campus and metropolitan networks
• Long-distance fiber connections up to 20 km
• Replacing faulty SFP modules in network equipment
• Connecting routers and switches with single-mode fibre ports

Key specifications

• Data rate: 1 Gbps
• Fiber type: single-mode
• Maximum reach: up to 20 km
• Form factor: SFP (hot-pluggable)
• Connector type: LC
• Wavelength: nominal 1310 nm
• Power consumption: low (typical for SFP-class modules)
• Operating temperature range: commercial temperature class

How to use

Insert the SFP transceiver into an empty SFP slot on the network device until it latches; then connect the single-mode LC fibre cable to the transceiver. The device should detect the module automatically and configure the link according to the connected equipment settings. For replacement, power down the device if recommended by the vendor, remove the faulty module, insert the new transceiver and reconnect fibre cables following standard ESD and handling precautions.

Recommendations

Use certified single-mode LC fibre and clean connectors before insertion to ensure optimal signal quality. Verify compatibility with the host equipment and check link parameters after installation. Avoid bending fiber beyond recommended radii and operate the module within specified temperature limits for reliable long-term performance.
