SFP-transceiver CBO SFP-1G-LX-20KM-IB-BO 1,25 Gbps singlemode LC, 20 km

The BlueOptics SFP transceiver SFP-1G-LX-20KM-IB-BO is a compact small form-factor pluggable module designed for single-mode fiber links. Supporting a 1.25 Gbps data rate and an LC duplex connector, this transceiver provides point-to-point optical connectivity for Gigabit Ethernet and other optical network protocols over distances up to 20 km. The hot-pluggable module simplifies upgrades and replacements in switches, routers and media converters while maintaining compatibility with standard SFP interfaces.

Advantages

This SFP transceiver offers stable 1.25 Gbps performance for long-reach single-mode connections, a compact hot-pluggable design for easy installation and maintenance, and an industry-standard LC connector for broad compatibility with fiber patching infrastructure. Its optical reach of up to 20 km enables network segmentation and inter-building links without the need for additional repeaters. The module is suitable for mixed-vendor environments due to its standard SFP form factor and interoperable physical characteristics.

Suitable for

• Gigabit Ethernet uplinks between switches and routers
• Long-distance links between network closets or buildings up to 20 km apart
• Media converters and optical line cards requiring SFP modules
• Network upgrades where single-mode fiber infrastructure is present

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode
• Connector: LC duplex
• Maximum link length: up to 20 km (single-mode)
• Form factor: SFP (hot-pluggable)
• Application: Gigabit Ethernet and optical networking protocols

How to use

Ensure the host device supports SFP modules and the fiber cabling is single-mode with LC connectors. Power down the port if required by the equipment documentation, insert the transceiver into the SFP slot until it clicks into place, and connect LC patch cables to the transmit and receive ports following correct polarity. Restore power and verify link status via the host device management interface or indicator LEDs. Monitor signal levels and error statistics through the host system to confirm stable operation.

Recommendations

Store and handle the transceiver in a clean, dry environment and avoid touching the optical interfaces. Use proper dust caps when the module is not connected, and follow ESD precautions during installation. For reliable long-distance performance, use certified single-mode fiber and quality LC patch cords, and verify link budget and connector cleanliness if experiencing signal issues.
