YOKOGAWA OTDR AQ7277B

The YOKOGAWA OTDR AQ7277B delivers precise, high-resolution optical time domain reflectometry for advanced fiber-optic network testing and troubleshooting. Designed for demanding applications in optical communications, photonic research, and telecommunications maintenance, this remote OTDR module—integral to Remote Fiber Test Systems (RFTS)—combines robust performance with user-friendly operation.

The YOKOGAWA OTDR AQ7277B Remote OTDR enables efficient fault detection and characterization over long fiber distances. Its compact design enables automated remote measurements and monitoring as part of an RFTS, minimizing downtime and ensuring optimal network performance. Whether you’re verifying installation quality, troubleshooting fiber link issues, or continuously monitoring network health, the AQ7277B delivers clear, reliable results.

Key Features

High-Resolution: Achieve superior accuracy in detecting reflections, losses, and faults along fiber-optic cables—pinpointing issues with precision.

Live Network Testing: This OTDR supports testing at a maintenance wavelength (1650 nm) for fibers with live communications. A built-in cut filter isolates the communication signals from the measurement, ensuring accurate results even when the fiber is in active use.

Remote Monitoring: Built with remote measurement and monitoring capabilities via Ethernet and USB connectivity, the AQ7277B enables OTDR measurements and continuous tracking of network conditions from a distance. This feature is necessary in RFTS applications for installations in hard-to-reach or hazardous environments.

Software Connectivity: SCPI style commands are supported with Visual Studio (C/C++/C#/VB) documentation and sample programs.

PON System Support: Designed to support Passive Optical Networks (PON) with high-port-count splitters.

Compact Design: Engineered for challenging field conditions, its durable construction and reduced volume (60% smaller than previous models) enhance mountability and integration into RFTS.

Versatile: Supports a wide range of fiber types and test parameters, making it ideal for both routine maintenance and advanced optical research. In addition to the standard models, custom engineered Remote OTDR models can also be requested.
