Novel OTDR Effects in Determining Losses of Single-Mode Fibers and Splices,

Pagination or Media Count:
OTDR effects on fiber attenuation and splice loss are studied. Fiber group index or group delay is best determined by measurement, rather than from the refractive index. In this way, fiber and cable differences are accounted for. Cursor placement is important in length determination, and a fiber input pigtail and output reflection are desirable.
