ABSTRACT:
A one-shot method of making an optical fiber package (FIG. 1) for a submarine cable. A plurality of fibers (1) are fed into a space delimited by one or more elongate elements from which a tubular structure (3) can be formed, for example a C-section. A liquid filling material, such as a two-part exothermic curing polyurethne, mixed by static mixer (16), is injected into the C-section which is then closed by a die (17). The filling material rapidly cures to a resilient solid (2) in which the fibers are embedded before hauler (18) is reached. The fibers are spaced apart from one another and the tubular structure by means including a guide structure (14,15) as they enter the C-section and this is maintained in the cured material.
