SFP optický transceiver CBO SFP-1G-LX-20KM 1G 20 km

CBO SFP-1G-LX-20KM is an SFP fiber optic transceiver that supports a 1 Gbps data rate over single-mode fiber for link distances up to 20 km. Designed for installation in devices with standard SFP slots, this module provides an optical uplink option for switches, routers and media converters to extend network reach and interconnect remote sites. The transceiver implements typical LC duplex optical connectors and is intended for long-distance, low-latency links in enterprise and carrier environments.

Advantages

The module offers a compact SFP footprint that conserves port space while delivering gigabit performance and predictable optical reach. Its single-mode 20 km capability enables connections between buildings or across campus networks without electrical conversion. Compatibility with common SFP-equipped network devices allows straightforward integration into existing infrastructure, and the optical design reduces susceptibility to electromagnetic interference compared with copper links.

Suitable for

• Optical uplinks between switches in enterprise LANs
• Long-distance links for campus or branch connectivity
• Interconnects for routers and media converters with SFP ports
• Telecom edge and aggregation links requiring 1 Gbps speed

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1 Gbps (gigabit Ethernet / 1G fibre channel compatible)
• Optical fiber type: single-mode fiber (SMF)
• Maximum link distance: up to 20 km over single-mode fiber
• Connector type: LC duplex
• Transmission medium: optical

How to use

Insert the transceiver into an available SFP slot on the switch, router or media converter until it clicks into place. Connect LC duplex single-mode fiber patch cables between the module and the remote device, observing proper transmit/receive orientation. After physical installation, verify link status and negotiate speed on the network device per its interface configuration. Monitor optical receive power and link indicators to ensure stable operation.

Recommendations

Use single-mode LC duplex patch cords rated for the required distance and avoid tight bends near the connector. Confirm that the host device supports 1 Gbps SFP modules and enable appropriate interface settings; check optical power budgets for runs approaching the 20 km limit.
