Production of optical fiber ribbons for use in telecommunication cables involves forming groups of fibers, coating with resin, applying an envelope resin coating and hardening both coatings together by UV irradiation

摘要

Preparing a optical fiber ribbon comprising 2 or more separable sub-units (10, 20) located on a common plane by applying a UV hardenable resin to groups (1, 1') of fibers to form first envelopes, applying a second UV hardenable resin, and irradiating in a single step, rather than irradiating each coating separately. An Independent claim is included for a optical fiber ribbon obtained by the method.
