Fiber optic OTDR tester Lightwin OTDR 40 FTTX Singlemode with touchscreen

Lightwin OTDR 40 FTTX Singlemode with touchscreen is a handheld fiber optic OTDR tester designed for singlemode networks and FTTX deployments. It performs optical time-domain reflectometry to detect and locate faults, measure fiber length, and characterize connectors, splices and events along the fiber. The device integrates a touchscreen interface for on-site operation and viewing of trace results, providing technicians with practical diagnostics for installation, maintenance and troubleshooting of metropolitan, access and FTTH networks.

Advantages

The tester offers a compact, portable form factor with touchscreen controls that simplify navigation and result interpretation. It provides accurate distance measurement and event detection for singlemode fibers, enabling rapid localization of breaks, high-loss connections and reflective events. Built-in data storage and reporting capabilities allow technicians to save traces and export results for documentation and further analysis.

Suitable for

• FTTX and FTTH installation and acceptance testing
• Field troubleshooting and fault locating in singlemode access networks
• Maintenance and verification of metropolitan and campus fiber links
• Characterization of connectors, splices and in-line events

Key specifications

• Test type: Optical Time Domain Reflectometry (OTDR) for singlemode fiber
• Display: Integrated touchscreen for trace viewing and menu navigation
• Functions: Fault location, fiber length measurement, event and loss characterization
• Portability: Handheld design for field use
• Data handling: On-board storage and exportable trace files for reporting

How to use

Power on the Lightwin OTDR 40 FTTX Singlemode and select the appropriate singlemode test parameters for the fiber under test. Connect the fiber to the OTDR launch/test port using suitable connectors or a launch cable, and initiate a trace via the touchscreen. Review the displayed trace to identify events, measure distances and evaluate loss values. Save relevant traces to internal storage and export them to a computer or reporting system as required.

Usage recommendations

Use a proper launch/auxiliary cable for short fiber segments and connector characterization, clean all connectors before testing, and select test settings (pulse width, range and resolution) appropriate to the fiber span to obtain reliable measurements. Regularly back up trace files and follow local safety practices when working with fiber optic equipment.
