VIAVI OneAdvisor 1000 DTSS Portable Distributed Temperature and Strain Sensing Instrument
Portable Brillouin OTDR instrument for simultaneous distributed temperature and strain sensing along fiber optic cables and fiber-enabled assets.
Overview
The VIAVI OneAdvisor 1000 DTSS is a portable instrument for Distributed Temperature and Strain Sensing (DTSS) and is part of the VIAVI NITRO Fiber Sensing solution. It uses fiber optic cables as the sensor to provide real-time information about the temperature and strain exerted by the environment in and around fiber optic cables, hybrid cables and fiber-enabled assets.
The instrument is based on Brillouin OTDR (B-OTDR) technology and provides absolute measurements of temperature and strain along extensive lengths of fiber. Temperature and strain are measured simultaneously in one unit, with decorrelation of the two effects (patented). Measurements are single-ended and require access to only one fiber.
Typical uses include assessing the integrity of telecom optical fibers and data center interconnects (DCI), and structural health assessment of fiber-enabled assets in power utilities, pipelines, bridges, buildings and other infrastructure.
Platform and connectivity
The OneAdvisor 1000 DTSS is a battery-operated multi-test platform with a large touchscreen user interface. It can be expanded with additional capabilities such as OTDR testing and connector inspection. Bluetooth, WiFi and Ethernet connectivity with Smart Access Anywhere (SAA) allow remote control and operation.
The same technology is also available as the rack-mounted Fiber Test Head (FTH-DTSS) for permanent monitoring, either in OEM mode or with the VIAVI Remote Fiber Test System (ONMSi).
