The Anritsu MT9083B ACCESS Master is an Optical Time Domain Reflectometer (OTDR) engineered for testing and maintaining optical fiber networks across FTTx, CATV, LAN, access, and metro deployments. This field-portable instrument delivers high-resolution fault location and fiber characterization by identifying breaks, bends, connector issues, and other anomalies within fiber optic links with exceptional precision.
Technical Specifications
OTDR Performance
• Dynamic range: up to 42 dB, enabling measurement of fiber spans exceeding 200 km
• Event dead zone: less than 1 meter (typically 80 cm)
• Sampling resolution: 5 centimeters
• Pulse widths optimized at 100 ns for balanced measurement distance and resolution
• Dual-mode operation: HIGH RESOLUTION (HR) for superior deadzone performance and ENHANCED RANGE (ER) for extended distances
Wavelength Support
