Distance measurement Physical unit = metre (m) = the length of the path travelled by light in vacuum during a specific fraction of a second (1/299 792 458 s).
In 1957, the first Tellurometer, designed by South African, Dr. T.L. Wadley, was ... The Tellurometer used microwaves to measure distances up to 80km day or night. ...
As fiber grows more common, network owners, network technicians and network installers are paying more attention to the two crucial devices for certifying fiber optical cable: the Optical Loss Test Set (OLTS) and the Optical Time Domain Reflectometer (OTDR). While the measurements taken by these instruments seem similar, they perform distinct yet important roles in the fiber certification process. This paper explains how each product works and how they complement each other to prevent network problems.

When we make an OTDR (Optical Time Domain Reflectometry) measurement, we use the launch cable to allow the trace to settle down after the pulse(s) are sent into the fiber, allowing us to see and analyse the start of the fiber being tested. This is because a large event will be seen in front of the connection on the trace usually caused by reflectance from the connector on the OTDR, thus not allowing us to make a good measurement of the first connection. The launch fiber also overcomes the issue of any dead zone (unseen event) that may occur if the pulse width is wider than the distance to a connector a short distance away from the OTDR connector.
