Paper Abstract

Photobleaching at 340 and 1300 nm wavelengths of three multimode silica fibers under steady-state gamma irradiation (2 x 480 Gy, 120 Gy/h) at room temperature was studied as regards induced loss and recovery kinetics. Significant differences in behaviour between two pure silica-core fibers (plastic clad QSF 200 A and fluorine doped-clad AS 200 -300 from Quartz et Silice) and a germanium doped-core fiber 7020/250 from Compagnie Lyonnaise de Transmissions Optiques are presented. The hardening up to 0.1 MGy of a short bidirectional data link designed to operate a servomanipulator in a hot cell is described as an example of application.
