Optical Time Domain Reflectometer (OTDR)

An optical time domain reflectometer (OTDR) is a precision instrument used to locate events or faults along a fiber link, typically within an optical communications network. The OTDR launches a series of high speed optical pulses into the fiber to be measured. Various events on the fiber generates a Rayleigh back scatter that returns to the OTDR and the strength of the return pulses are measured and integrated as a function of time, and plotted as a function of fiber length. The horizontal axis is the distance and the vertical axis is the loss.

OTDRs are mainly used in the optical fiber installation and maintenance servicing of access networks (communications links between telephone exchanges and telephone poles) and user networks (communications links between user sites and telephone poles)

AQ1000 is specifically designed to increase the productivity of field personnel working on the installation and deployment of optical access networks such as Fiber To The Home (FTTH). Although it is positioned as an entry-level model, it still retains Yokogawa’s established standards of quality/reliability and features characteristics which are usually present in higher-level models, such as a high-quality capacitive multi-touch touchscreen and wireless connectivity. Wavelengths: 1310 / 1550 nm Dynamic ranges: 32 / 30 dB Size: 185 mm (W) × 116 mm (H) × 56 mm (D)    ( 7.3" (W) × 4.6" (H) × 2.2" (D) ) Weight: 660 g   ( 1.46 Lbs )
