Transceptor SFP de fibra ótica CBO SFP-1G-LX-20KM para 1 Gbit/s, monomodo, 20 km

CBO SFP-1G-LX-20KM is a single-mode fiber optic SFP transceiver module that supports 1 Gbps data transmission over distances up to 20 km. Designed for installation in standard SFP ports on network switches and routers, this module provides a compact, hot-pluggable solution for creating long-distance uplinks, backbone links and fiber extensions in enterprise, data centre and service provider networks.

Advantages

The transceiver offers a small form-factor, low power consumption and compatibility with common SFP interfaces, enabling straightforward integration into existing network equipment. Its single-mode optical design and 20 km reach make it suitable for medium-distance fiber runs while maintaining consistent 1 Gbps throughput. The module's hot-pluggable nature allows replacements or upgrades without powering down connected devices, reducing maintenance windows.

Suitable for

• Long-distance uplinks between switches and routers
• Backbone fiber links within campus and metro networks
• Fiber extensions to remote racks, buildings or cabinets
• Enterprise, data centre and ISP access layer deployments

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Optical mode: single-mode fiber (SMF)
• Maximum reach: up to 20 kilometres over single-mode fiber
• Connector type: LC duplex optical interface
• Form factor: SFP (Small Form-factor Pluggable), hot-pluggable
• Wavelength: typical long‑reach wavelength for single‑mode operation
• Power consumption: low-power SFP class module suitable for switch/router SFP slots

How to use

Insert the SFP module into an available SFP slot on a compatible network switch or router until it clicks into place. Connect LC duplex single-mode fiber patch cords between corresponding transceiver ports at each end of the link, respecting transmit/receive polarity. Configure the network interfaces on the connected devices for 1 Gbps operation and verify link status through device management or indicator LEDs. For replacement, hot-swap the module while the host device remains powered on, following the equipment manufacturer's ESD and handling guidelines.

Recommendations

Use single-mode LC duplex patch cords and confirm fibre polarity before powering equipment. Ensure both ends of the link use compatible single-mode transceivers rated for similar reach and wavelength. Avoid bending fiber beyond specified bend radius and follow ESD precautions when handling the module to maintain reliable optical performance.
