OTDR (Optical Time Domain Reflectometer) Launch Fiber Cable Box is a device used in fiber optic testing to improve the accuracy and reliability of OTDR measurements. It is a box-like enclosure that contains a length of optical fiber known as the launch cable. The launch cable is designed to help control the launch conditions of the OTDR pulse, reducing measurement errors caused by reflections and fluctuations at the beginning of the fiber under test. By providing a known and consistent launch condition, the OTDR launch fiber cable box enables more precise measurements of fiber length, loss, and other characteristics, ensuring accurate assessment and troubleshooting of fiber optic networks.
