SFP-glasvezeltransceiver CBO SFP-1G-LX-20KM — 1 Gbit/s, singlemode, 20 km

CBO SFP-1G-LX-20KM is an SFP fiber optic transceiver engineered for 1 Gbps single-mode links up to 20 km. It uses the standard LC duplex connector and a hot-pluggable SFP form factor to integrate with compatible network switches, routers and media converters. The module is suitable for common network infrastructures including backbone, campus and ISP connectivity where single-mode fiber and long-reach 1 Gbps links are required.

Advantages

The transceiver offers a compact, hot-swappable design that minimizes downtime during installation or replacement. It supports a 1 Gbps data rate over single-mode fiber to distances of up to 20 km, providing a balance between reach and cost for many enterprise and service-provider scenarios. The LC duplex interface and SFP form factor ensure wide compatibility with devices that accept standardized SFP modules.

Suitable for

• Backbone uplinks between distribution and core switches over single-mode fiber
• Campus network segments requiring 1 Gbps links across buildings
• ISP last-mile or aggregation links where 20 km reach is sufficient
• Media converters and fiber-enabled routers or switches with SFP slots

Key specifications

• Data rate: 1 Gbps (SFP multi-rate not required)
• Fiber type: single-mode fiber (SMF)
• Maximum link distance: up to 20 km
• Connector type: LC duplex
• Form factor: SFP (hot-pluggable)
• Wavelength: typical LX-class single-mode transmission
• Power and management: industry-standard SFP electrical interface (host-managed via supported devices)

How to use

Power off or consult your device hot-swap procedures if needed, then insert the SFP module into a compatible SFP slot until it latches. Connect LC duplex single-mode fiber patch cables with correct polarity to the module’s connectors. Configure the host device interface (speed/duplex and any required administrative settings) according to the switch, router or media converter documentation. Verify link status and diagnostics through the host device management interface if available.

Recommendations

Ensure clean fiber connectors and correct cable type (single-mode) prior to connection. Use dust caps when the transceiver is not in use and avoid exceeding the specified 20 km link distance to maintain signal integrity. Confirm compatibility with your network equipment’s SFP compatibility list where vendor-lock restrictions apply.
