WebOverview Optical Return Loss (ORL) is the ratio between the light launched into a device and the light reflected by a defined length or region. ORL can be measured using two measurement techniques: optical continuous wave reflectometry (OCWR) or optical time domain reflectometry (OTDR). Both techniques are described in IEC 61300-3-6. WebIn practical OTDR measurement terms, backscattering characteristics are mostly influenced by the refractive index profile and geometrical properties of the fiber.

WebThe Coherent Optical Time Domain Reflectometer (C-OTDR) is the only way to accurately measure and characterize the optical submarine network allowing accurate fault location to within 10 meters. How does it work? The C-OTDR works utilizing the Rayleigh backscatter caused by the impurities inherent in optical fiber to reflect light back to The reliability and quality of an OTDR is based on its accuracy, measurement range, ability to resolve and measure closely spaced events, measurement speed, and ability to perform satisfactorily under various environmental extremes and after various types of physical abuse. The instrument is also judged on the basis of its cost, features provided, size, weight, and ease of use. haspa joker comfort kostenWebTelecom Test and Measurement www.EXFO.com Table 2.
