Abstract

Fiberoptisk overføringsledning (24) med en eller flere lysledere (10) av enkeltmodustypen. Lyslederen omfatter en optisk fiber (12) som er omsluttet av en indre kappe (14). Utenpå den indre kappe er lagt en ytre kappe (16, 18) bestående av et indre lag (16) og et ytre lag (18). For å redusere overf øringsledningens henholdsvis lyslederens f remstillingskost- nad er det ytre lag (18) av termoplastisk materiale hvis tilsynelatende viskositet ved smeltetemperaturen er maksimalt om- kring 100 På ¿ B ved en skjærhastighet som minst er 100 s'1. Den indre kappe (14) og det indre lag (16) av den ytre kappe er gjerne av en harpiks som er retikulerbar ved ultrafiolett bestråling.
