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

The SFP Fiber Optic Transceiver CBO SFP-1G-LX-20KM is a compact, hot-pluggable module that provides 1 Gbps Ethernet connectivity over single-mode fiber for links up to 20 km. Designed for compatibility with switches, routers and media converters featuring standard SFP slots, this LX-class transceiver supports long-distance point-to-point connections and integrates into campus networks, data center interconnects and telecom aggregation links.

Advantages

This SFP module offers reliable single-mode transmission at 1 Gbps with a reach of up to 20 km, enabling cost-effective fiber extension without modifying existing equipment racks. Its hot-pluggable SFP form factor simplifies installation and replacement, while the LX optics provide stable performance over metropolitan and campus distances. The transceiver is engineered for interoperability with industry-standard SFP ports and typical network equipment, reducing deployment complexity.

Suitable for

• Long-distance Ethernet links between buildings or floors over single-mode fiber
• Interconnecting switches and routers in campus and enterprise networks
• Data center uplinks and server farm interconnects requiring 1 Gbps fiber links
• Media converters and telecom equipment with SFP ports for fiber extension

Key specifications

• Data rate: 1 Gbps Ethernet
• Fiber type: single-mode
• Maximum link distance: up to 20 km
• Wavelength/type: LX-class optics (long wavelength)
• Form factor: SFP (hot-pluggable)
• Connector: LC duplex
• Power consumption: typical SFP-class low power operation

How to use

Insert the transceiver into a compatible SFP slot on your switch, router or media converter while the device is powered on or off, as the hot-pluggable design supports live replacement. Connect LC duplex single-mode fiber patch cables to the transceiver ports, ensuring correct transmit/receive orientation. Configure the connected network ports for 1 Gbps operation if required by your equipment; most modern switches will auto-negotiate with the module. Verify link status and optical signal levels through the host device management interface.

Recommendations

Use single-mode LC duplex fiber for runs up to 20 km and verify end-to-end loss budget for longer or older fiber plants. Avoid bending the fiber beyond recommended radii, and ensure connectors are clean before mating to reduce insertion loss. When replacing modules, confirm SFP slot compatibility and, if necessary, update host device settings to recognize third-party transceivers.
