ZHWCOMM JW3302B-SM-OTDR-1310-1550nm-30/28dB Handheld OTDR English version Optical Time Domain Reflectometer Product Description JW3302 OTDR is the preferred choice for the measurement of optical fiber’s specifications. With OTDR, you can make assessment of one single optical fiber or a whole optical fiber chain. Especially, you can directly observe loss and events distribution of optical fiber chain. OTDR check the transmission quality of optic fiber through measurement of backward scattered lights. Standard organizations like International Telecom Union (ITU) define backward scattered lights as effective analysis means of measurement of optical fiber loss.Backward scattering is also the only effective way of connector inspection, which can be applied to measure the length of optical fiber, too. Therefore, OTDR is a useful tool for optical fiber manufacturing, installation and maintenance.
