High Precision optical time-domain reflectometer (OTDR) Fiber optic OTDR Tester 1310/1550nm
Optical Time Domain Reflectometer (OTDR) acquires and analyses the information of backscattering and reflective light propagating in fiber, based on the light backscatter and Fresnel reflection principle, to get the length, loss, fault points, light return loss, connector loss and so on. It is an essential tool for optical cable construction, deployment and maintenance.
