Fiber Optic SFP Transceiver CBO SFP-1G-LX-20KM — 1 Gbps, 20 km, LC

The CBO SFP-1G-LX-20KM is a BlueOptics fiber optic SFP transceiver designed for 1 Gbps Ethernet links over single-mode fiber. The module supports a transmission range of up to 20 km and uses an LC duplex connector for optical interfaces. Compatible with a wide range of switches, routers and media converters, this transceiver provides a compact hot-swappable solution to extend network links between buildings, wiring closets or data center racks while maintaining standard Ethernet performance.

Advantages

This SFP transceiver delivers stable 1 Gbps throughput with long-reach capability to 20 km on single-mode fiber. The LC duplex connector and small form-factor pluggable design enable easy installation and replacement without powering down equipment. Built to industry optical specifications, the module is suitable for use in mixed-vendor environments and supports transparent Ethernet transport over optical links.

Suitable for

• Extending Ethernet links between buildings or floors
• Connecting switches and routers across campus or data center racks
• Upgrading uplinks from copper to fiber for longer reach
• Integrating with media converters for fiber-to-copper transitions

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Maximum transmission distance: up to 20 km over single-mode fiber
• Connector type: LC duplex
• Fiber type: single-mode (SMF)
• Form factor: SFP (Small Form-factor Pluggable), hot-swappable
• Wavelength: long wavelength single-mode standard (LX)

How to use

Insert the SFP transceiver into an available SFP port on a compatible switch, router or media converter until it latches. Connect LC duplex fiber patch cables between corresponding transmit and receive ports on each end of the link, ensuring correct polarity. After physical installation, confirm link status via the device LEDs or management interface and verify the network configuration (speed/duplex and VLAN settings) as required. Observe recommended electrostatic discharge (ESD) precautions and keep protective caps on the optical ports when not connected.

Recommendations

Use single-mode LC patch cords with proper polarity and low insertion loss, test optical power and link quality after installation, and ensure both ends of the link use compatible 1 Gbps LX optics to guarantee reliable operation up to 20 km.
