SFP fiber transceiver CBO SFP-1G-LX-20KM-MR-BO, 1.25 Gbps, LC, single-mode, 20 km

CBO SFP-1G-LX-20KM-MR-BO is an SFP fiber optic transceiver module that supports a 1.25 Gbps data rate and uses an LC connector for single-mode fiber links up to 20 km. The module fits the compact SFP form factor and is hot-pluggable, allowing upgrades and optical uplink deployment in switches, routers and media converters without powering down the host device. It is intended for point-to-point single-mode connections and optical uplinks in enterprise and carrier networks.

Advantages

The transceiver provides a stable 1.25 Gbps link over single-mode fiber for distances up to 20 km using an LC duplex interface. Its compact SFP design supports hot-swapping to minimize downtime during network maintenance. Compliance with common SFP electrical and optical interfaces ensures interoperability with a wide range of network devices, while the module’s wavelength and optical budget are balanced for typical access and aggregation uplink scenarios.

Suitable for

• Optical uplinks between switches and routers
• Long-distance links in campus and branch networks
• Media converters and fiber-to-Ethernet conversions
• Edge and aggregation layer connections in enterprise networks

Key specifications

• Data rate: 1.25 Gbps
• Connector: LC duplex
• Fiber type: single-mode
• Maximum link distance: 20 km
• Form factor: SFP (hot-pluggable)

How to use

Insert the SFP module into a compatible SFP slot on a switch, router or media converter until it clicks into place. Connect single-mode LC-terminated fiber optic cable to the module’s LC connector, observing correct transmit/receive orientation. Configure the host device’s port settings as required for 1.25 Gbps operation and monitor link status through the device management interface. To remove the module, perform any required shutdown or port disable procedure on the host device if recommended, then press the module’s release latch and pull it out carefully.

Recommendations

Use single-mode fiber with matching LC connectors and maintain appropriate fiber cleanliness to ensure reliable optical performance. Verify compatibility with your network equipment and firmware, and follow ESD precautions when handling the transceiver.
