Optical Time Domain Reflectometer

An Optical Time Domain Reflectometer (OTDR) is a device used in the field of telecommunications and networking to measure the characteristics of optical fibers. It is classified under the supply class Electrical And Electronic Properties Measuring And Testing Instruments in the supply group Instruments And Laboratory Equipment.

OTDRs work by sending a pulse of light into an optical fiber and measuring the amount of light that is reflected back. This allows them to determine the length of the fiber, as well as identify any faults or issues such as breaks, bends, or splices. OTDRs can also measure the loss of signal strength along the fiber, known as attenuation, and can provide a graphical representation of the fiber's characteristics.

These devices are commonly used in the installation, maintenance, and troubleshooting of optical fiber networks. They are essential for ensuring the proper functioning and performance of these networks, as well as for identifying and resolving any issues that may arise.

In summary, an Optical Time Domain Reflectometer is a specialized instrument used for measuring and testing the properties of optical fibers in telecommunications and networking applications.
