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.
