Optical Time Domain Reflectometer

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).

Our broad lineup of OTDRs offer cost performance, field durability, and applicable dynamic range. With thirty years of innovation in reflectometry design we deliver technology solutions where you need them most.

  • This 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.

  • Responding to the growing needs for reliable and ease-of-use field test instruments for installation and maintenance of fiber optic networks, Yokogawa AQ7280 Optical Time Domain Reflectometer (OTDR) is designed to empower field technicians to make fast and precise measurements with confidence.The AQ7280 satisfies a broad range of test and measurement needs in analyzing optical networks from access to core.

  • High performance OTDR module for RFTS (Remote Fiber Test System)

  • The AQ1200 Multi Field Tester OTDR is a compact and lightweight handheld OTDR optimized for the installation and maintenance of optical fiber cables. Designed with ease of use in mind to simplify field testing, improve work efficiency and ensure qualify results. Seven models are offered, each with unique wavelength(s) based on their specific application.

  • AQ7932 is application software that performs analysis of trace data from the OTDR on a PC, and conveniently creates professional reports. The built-in report creation wizard function makes this task simple, quick and easy.

Overview:

The Optical Time Domain Reflectometer (OTDR) is an instrument capable of detecting and measuring fiber-optic break points or splice points, as well as distancerelated data, in fiber-optic communication networks. In line with the recent spread of “Fiber to the Home” (FTTH) technology, there is a growing need to detect these break and splice points in short-distance networks with even greater accuracy. In order to meet this need, we have developed OTDRs with a maximum distance resolution of 5cm. Furthermore, as a new measurement application we will introduce live-line measurement technology using a 1650-nm wavelength, different from the 1310/1550nm working wavelengths used for communication lines.

Overview:

This paper describes a compact optical channel monitor and a delayed interferometer having free-space optical elements such as lenses or mirrors, as an application of microoptics. These devices have been developed to be built into dense wavelength division multiplexing (DWDM) transmission systems. These optics use a Gaussian beam which is emitted through single-mode optical fibers and located near the optical axis. This paper explains the optical designs of these devices based on the Gaussian beam's behavior.

Product Overviews

    Overview:

    The AQ7270 OTDR maximizes the total working time during on-site tests as the time to power up the device, make measurements, and analyze and store the measurement results are significantly reduced. The measurement results can easily be transmitted to computers using the USB interface or the Ethernet. The analysis software (optional), helps with preparation of computer-generated reports.
