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

The SFP Fiber Optic Transceiver CBO SFP-1G-LX-20KM is a single-mode 1 Gbps optical module designed for Ethernet links up to 20 km. The compact SFP form factor fits standard SFP ports and supports hot-swap installation, allowing fast replacement without powering down network equipment. The transceiver uses an LC connector and is compatible with switches, routers and media converters that accept standard 1 Gbps SFP modules.

Advantages

This transceiver delivers stable 1 Gbps performance over single-mode fiber for medium-distance connections up to 20 km. Its SFP form factor provides flexibility and easy integration into existing network hardware. The LC interface and industry-standard signaling ensure broad compatibility with networking equipment. Low power consumption and hot-swap capability reduce downtime during maintenance or upgrades.

Suitable for

• Enterprise network uplinks between buildings or floors
• ISP and telecom access links requiring 1 Gbps over single-mode fiber
• Interconnecting switches and routers in data centers or server rooms
• Media converters and network equipment expansions

Key specifications

• Data rate: 1 Gbps
• Fiber type: single-mode
• Maximum reach: 20 km
• Form factor: SFP (hot-pluggable)
• Connector: LC duplex
• Wavelength: typical 1310 nm
• Compatibility: standard SFP ports on switches, routers and media converters
• Power consumption: low (typical for SFP-class transceivers)

How to use

Install the module into a free SFP slot on compatible network equipment while the device is powered if the equipment supports hot-swapping; otherwise, follow the device manufacturer’s power-down procedure. Connect single-mode fiber with LC duplex connectors and ensure correct transmit/receive orientation. Verify link status via the equipment’s interface and configure network settings as required for 1 Gbps Ethernet operation. If the module is not immediately recognized, check compatibility settings or consult the switch/router documentation for SFP module support.

Recommendations

Use single-mode fiber with appropriate cleaning of LC connectors before connection. For links approaching the maximum distance, verify fiber attenuation and use proper splicing or patching practices. Keep spare transceivers for quick replacement and store unused modules in anti-static packaging.
