Optical Time Domain Reflectometer OTDR Pro MAX 5701 — singlemode/multimode testing

OTDR Fiber Optic Reflectometer Pro MAX 5701 — singlemode/multimode testing is a handheld instrument designed for characterizing fiber optic links in both singlemode and multimode networks. The device measures optical distance to events, insertion loss and reflectance, and records trace files for later analysis. It detects and locates connectors, splices, bends and breaks, and provides numerical and graphical information to document link quality during installation, maintenance and troubleshooting of fiber optic cabling.

Advantages

The unit combines support for singlemode and multimode measurements in a single portable housing, simplifying testing across mixed networks. Fast acquisition and automated event detection reduce test time while trace storage enables consistent reporting and review. The device offers clear distance resolution and loss measurement accuracy suitable for field use, with intuitive operation aimed at technicians performing installation and fault isolation.

Suitable for

• Installation testing of new fiber links in singlemode and multimode networks
• Maintenance checks and periodic verification of link attenuation and event locations
• Troubleshooting and pinpointing faults such as breaks, high-loss splices or faulty connectors
• Documentation and archiving of OTDR traces for quality assurance and handover

Key specifications

• Measurement modes: singlemode and multimode fiber testing
• Measured parameters: event distance, insertion loss, reflectance and trace data
• Graphical trace output for event identification and analysis
• Portable handheld form factor for field use
• Internal trace storage for multiple test records

How to use

Connect the OTDR to the fiber under test using appropriate adapters and launch/receive cables if required. Select the fiber type (singlemode or multimode) and an appropriate test wavelength and range. Start an automatic acquisition to capture the trace; review detected events and measured loss values on the instrument display. Save traces to internal storage for later analysis or transfer to a PC for reporting. Follow appropriate fiber handling and connector cleaning procedures before testing to ensure accurate measurements.

Usage recommendations

For reliable results, use a suitable launch/receive cable or pulse adapter when testing long fiber runs, keep connectors clean and free of contamination, and allow the OTDR to settle after connecting before recording the final trace. Use consistent test settings and wavelength selection when comparing traces over time.
