SFP transceiver CBO SFP-1G-LX-20KM-VA-BO, 1 Gbit/s, 1310 nm, LC, single-mode, 20 km

Single-port SFP optical transceiver CBO SFP-1G-LX-20KM-VA-BO delivers 1 Gbit/s data transmission over single-mode fiber for links up to 20 km. Operating at a 1310 nm wavelength with an LC duplex connector, this compact hot-swappable module is designed for use in Gigabit Ethernet and other fiber network applications. The transceiver fits standard SFP slots in switches, routers and media converters and provides a straightforward way to extend network reach with single-mode fiber.

Advantages

The transceiver provides a stable 1 Gbit/s connection over long distances while maintaining a compact SFP form factor that supports hot swapping without interrupting system operation. Using a 1310 nm optical interface and LC duplex connector ensures compatibility with common single-mode fiber infrastructures. The module's design focuses on interoperability with standard network equipment and simple integration into existing fiber links.

Suitable for

• Gigabit Ethernet uplinks between switches and routers
• Long-distance point-to-point fiber links up to 20 km
• Fiber connectivity for media converters and access devices
• Network backbone extensions in enterprise and campus environments

Key specifications

• Data rate: 1 Gbit/s
• Wavelength: 1310 nm
• Fiber type: single-mode
• Connector type: LC duplex
• Maximum reach: up to 20 km (single-mode fiber)
• Form factor: SFP (hot-swappable)

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 the LC duplex single-mode fiber cable, ensuring correct transmitter-to-receiver alignment between link endpoints. Use network management tools or device LEDs to verify link status and negotiate speed. If needed, remove the module by releasing the latch or pull-tab and replace it while the host device remains powered, following the equipment manufacturer's hot-swap guidance.

Recommendations

Ensure fiber connectors are clean and dust-free before making connections, and use appropriate dust caps when the module is not in use. Verify compatibility with the host device's supported SFP transceiver list and confirm fiber cable specs (mode and attenuation) to maintain reliable performance over the 20 km distance.
