SFP Transceiver CBO SFP-1G-LX-20KM — 1G single-mode fiber, 20 km range

The CBO SFP-1G-LX-20KM is a BlueOptics SFP fiber optic transceiver designed for 1 Gigabit Ethernet over single-mode fiber with a specified reach of up to 20 km. This compact, hot-pluggable module provides a reliable optical uplink option for switches, routers and media converters, enabling link extension between network sites and stable long-distance connectivity for enterprise, data centre and service provider environments.

Advantages

The transceiver supports standard SFP form factor compatibility and offers hot-swap capability for easy installation and maintenance without system downtime. It is optimized for single-mode fiber to deliver consistent performance over long distances and is suitable for deployment in mixed-vendor networks. The module is engineered to meet common interoperability and optical power requirements for 1 Gbit/s LX links while maintaining a compact footprint and low power consumption.

Suitable for

• Long-distance uplinks between switches or routers within campuses and enterprise networks
• Connections between data centre racks or between buildings over single-mode fiber
• Service provider access links and metropolitan area network segments
• Replacing or extending existing 1 Gbps LX optical links

Key specifications

• Interface: SFP (small form-factor pluggable), hot-pluggable
• Data rate: 1 Gigabit Ethernet
• Fiber type: Single-mode fiber
• Maximum reach: Up to 20 km (dependent on fiber quality and link conditions)
• Wavelength: Typical 1310 nm for LX single-mode transmission
• Connector type: Standard LC duplex
• Power consumption: Low-power SFP class (typical values depend on device implementation)
• Operating environment: Designed for use in networking equipment racks and chassis (consult device specifications for temperature ranges)

How to use

Install the module into a compatible SFP slot on a switch, router or media converter until it latches, and secure any retaining mechanisms if present. Connect single-mode fiber using LC duplex connectors, observe proper fiber handling and routing to avoid sharp bends, and ensure transmit/receive pair orientation is correct. After insertion and cabling, verify link status and correct operating speed on the host device. For safe removal, follow the host equipment procedure to power down or disable the port if required and pull the module straight out using the release tab.

Recommendations

Use certified single-mode fiber and quality LC connectors for optimal signal performance. Check compatibility with the host device firmware and vendor support policies when replacing transceivers in mixed-vendor environments. Maintain clean fiber endfaces and use dust caps when connectors are not in use to prevent contamination and signal loss.
