OTDR Launch Box
A fiber optic launch box is used with Optical Time Domain Reflectometers (OTDR) during fiber loss measurement. A launch box helps minimize the dead zone effect on the launch pulse when testing a fiber optic line. In order to measure a fiber optic line and obtain an accurate, complete picture of the system’s loss-which is a critical aspect of fiber commissioning—a launch test cable should always be used at both ends of the fiber link. Fiber optic OTDR launch boxes may be known in the market as dead zone box, pulse suppressor, fiber ring, fiber optic launch cable, etc.
