EXFO's dedicated OTDR packages provide advanced fiber characterization, high-accuracy measurements, and versatile field testing capabilities for single-mode, multi-mode, and mixed optical networks.

Overview

EXFO offers a range of dedicated OTDR packages designed for precise fiber testing, network validation, and troubleshooting. These solutions are widely used in fiber-to-the-home (FTTH), mobile RAN networks, data centers, and C-RAN deployments. The OTDR packages combine optical link mapping, power measurement, and connector health monitoring in a single device, allowing technicians to switch between testing modes without disconnecting the fiber under test .

Key Features

• Dynamic Range: Depending on the model, EXFO OTDRs offer a dynamic range from 27 dB up to 50.5 dB, suitable for short local fibers or long-haul trunk lines .
• Wavelength Support: Models cover 850 nm to 1650 nm, supporting single-mode, multi-mode, and tunable fiber testing .
• Pulse Duration: Adjustable from 3 ns to 20 µs, enabling minimal dead zones for short fibers and maximum dynamic range for long fibers .
• Port Flexibility: Field-swappable optical port connectors and integrated power measurement allow seamless transitions between testing and troubleshooting .
• Event Analysis: Automatic generation of event tables indicating distance, loss, and reflection for connectors, splices, splitters, and macrobends .
• Portability: Handheld and compact designs, such as the MaxTester 700D series, ensure stable operation in harsh field conditions .

Applications
