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

CBO SFP-1G-LX-20KM Fiber Optic Transceiver 1G 20 km is a single‑mode SFP module designed to provide reliable 1 Gbps Gigabit Ethernet links over fiber. The module supports a transmission distance up to 20 kilometers over single‑mode fiber and fits standard SFP ports on switches, routers and media converters. It enables long‑range uplinks and point‑to‑point connections where stable 1G performance and compatibility with SFP interfaces are required.

Advantages

The transceiver offers stable 1 Gbps throughput with low power consumption and hot‑plug capability for easy installation and maintenance. Its single‑mode design and 20 km reach make it suitable for campus backbones and telecom links. The SFP form factor ensures broad compatibility with a wide range of networking equipment that supports SFP modules.

Suitable for

• Long‑distance Gigabit Ethernet uplinks between buildings or network closets
• Campus networks and metropolitan area links requiring single‑mode fiber
• Router and switch SFP ports to extend network segments up to 20 km
• Telecom and service provider access links with 1G requirements

Key specifications

• Optical type: single‑mode fiber
• Data rate: 1 Gbps (Gigabit Ethernet)
• Maximum transmission distance: up to 20 km
• Form factor: SFP (small form‑factor pluggable)
• Wavelength: typical for LX single‑mode operation
• Interface: SFP electrical and LC duplex optical connector
• Hot‑plug capability and low power consumption

How to use

Insert the CBO SFP-1G-LX-20KM module into a compatible SFP slot on a switch, router or media converter while the host device is powered on or off, following device vendor guidance. Connect single‑mode fiber with LC duplex connectors and ensure correct transmit/receive orientation. Configure the host interface for 1 Gbps operation if necessary and verify link status via the device management interface or status LEDs.

Recommendations

Use certified single‑mode fiber (SMF) and quality LC connectors to achieve the specified 20 km link distance. Verify compatibility with the equipment vendor’s supported transceiver list and check fiber polarity and attenuation to ensure reliable operation.
