Research of attenuation spectrum in organic optical fiber

The main characteristic affecting on fiber transmission are attenuation and dispersion in optical fiber. The equipment of measuring attenuation has been set up in this letter. The attenuation in some organic optical fiber is measured. The lowest losses are 238dB/km at 670nm for PS core, 197 dB/km at 580nm for PMMA core, and 0.2dB/m at 650nm for C₆H₆ liquid-core optical fiber. Temperature and ultraviolet radiation affecting on loss in fiber are researched.
