ABSTRACT:
Optical fiber has a glass portion and at least one coating of crosslinked polymer material surrounding the glass portion, the coating being obtained by crosslinking a composition of (a) at least one radically crosslinkable oligomer containing at least two reactive functional groups and having a number average molecular weight lower than about 1,000, preferably between about 400 and about 900; (b) at least one cationically crosslinkable compound containing at least one reactive functional group; (c) at least one free radical photoinitiator; and (d) at least one cationic photoinitiator. Preferably, the coating is a secondary coating or, in the case of a ribbon of optical fibers, it is a common polymer coating known as a “common coating”.
