SFP-transceiver CBO SFP-1G-LX-20KM — 1 Gbit/s singlemode, 20 km

CBO SFP-1G-LX-20KM is a single-mode fiber optic SFP transceiver supporting a 1 Gbps data rate and a link distance up to 20 km. The module is designed for use in network equipment with SFP ports and provides a compact, hot-pluggable interface for long-distance uplinks, access aggregation and backbone connections. It supports standard SFP form factor compatibility and is suitable for integration into switches, routers and media converters where single-mode links are required.

Advantages

The transceiver offers a reliable 1 Gbps throughput over single-mode fiber for mid-range distances up to 20 km, helping to extend network segments without active repeaters. Its hot-pluggable SFP form factor allows quick replacement or upgrades without powering down the host device. The module conforms to common SFP mechanical and optical interfaces, enabling broad compatibility with equipment that accepts standard SFP modules.

Suitable for

• Long-distance uplinks between switches and routers
• Access aggregation in enterprise and campus networks
• Backbone connections within buildings or between nearby sites
• Media converters and fiber extension applications

Key specifications

• Data rate: 1 Gbps (full duplex)
• Fiber type: single-mode
• Maximum reach: up to 20 km over single-mode fiber
• Form factor: SFP (hot-pluggable)
• Optical interface: LC connector

How to use

Insert the SFP transceiver into an empty SFP port on a compatible switch, router or media converter until it clicks into place. Connect a single-mode LC-terminated fiber patch cable between transceiver ports at each end of the link, observing proper TX/RX orientation. Verify link status and speed on the host device and configure port settings as required by your network. To remove the module, disengage any retention latch and pull the transceiver straight out while the host is powered on or off according to the equipment’s maintenance policy.

Recommendations

Ensure the connected fiber is clean and the LC connectors are free of dust or debris before installation. Match fiber type and transceiver specifications at both ends of the link to avoid compatibility or reach issues. Follow equipment vendor guidance for supported transceiver models and any required configuration to enable 1 Gbps operation.
