Paper Abstract

The equipment described here, developed in Institute of Telecommunications and based on the swept frequency method enables to measure amplitude - frequency response of fiber samples, field installed optical fiber lines and LED's in the frequency range up to 600 MHz. Measurements of modal dispersion in optical fibers are performed in the 850 nm band, maximum permissible fiber attenuation is 30 dB. The set - up consists of wideband frequency response analyser, modulated GaAlAs CW laser source and optical receiver with APD photodetector. Non - standard applications of set - up components are also possible, such as short optical pulses monitoring. Additionally, examples of results of measurements made on graded index fibers manufactured in Poland, optical fiber line installed in Lodz and fiber optic LED's CQYP - 06F are presented.
