CBO SFP Transceiver SFP-1G-LX-20KM Fiber Optic 1Gbps LX 20 km

The CBO SFP Transceiver SFP-1G-LX-20KM Fiber Optic 1Gbps LX 20 km is a single-mode small form-factor pluggable (SFP) module designed for 1 Gbps Ethernet links over long distances. Using LX optics, it supports up to 20 km reach on single-mode fiber and fits standard SFP ports on switches, routers and media converters. The module provides a compact, hot-pluggable solution for extending network segments, creating backbone links or establishing point-to-point fiber connections where stable Gigabit throughput is required.

Advantages

This SFP transceiver offers compatibility with standard SFP interfaces and delivers consistent 1 Gbps performance with low power consumption. The LX optics and single-mode design allow reliable long-reach connectivity up to 20 km, reducing the need for intermediate devices. Hot-pluggable form factor enables easy installation and replacement without powering down network equipment, simplifying maintenance and upgrades.

Suitable for

• Uplink connections between switches and routers
• Long-distance fiber links in campus or enterprise networks
• Backbone and aggregation links requiring 1 Gbps throughput
• Point-to-point fiber connections between buildings or facilities
• Media converter and fiber transceiver deployments

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1 Gbps Ethernet
• Optical type: LX single-mode optics
• Maximum link distance: up to 20 km on single-mode fiber
• Connector type: LC duplex
• Wavelength: typical LX class wavelength for single-mode transmission
• Power consumption: low-power SFP class
• Operating temperature: commercial temperature range suitable for standard network equipment

How to use

Insert the SFP module into a compatible SFP port on a switch, router or media converter until it clicks into place. Connect single-mode LC duplex fiber patch cables to the module, observing transmit and receive polarity. Configure the connected network devices for 1 Gbps operation if necessary; most devices will auto-negotiate the link. For safe removal, follow the equipment manufacturer’s hot-swap procedure and handle the fiber interfaces with dust caps or cleaning tools to maintain optical performance.

Recommendations

Use single-mode fiber with LC duplex connectors and maintain correct TX/RX polarity. Keep connector endfaces clean and use appropriate dust caps when the transceiver is not connected. Verify device compatibility and link configuration in the network management interface, and confirm that fiber span and connector loss are within the module’s specified reach for reliable 20 km links.
