Abstract

1371740 Coated optical fibre STANDARD TELEPHONES & CABLES Ltd 29 March 1973 15097/73 Headings B5A and B5B An optical communications fibre comprising a glass optical fibre 1 and an axially orientated plastics coating formed by feeding the optical fibre 1 into a plastics tube 5 extruded from a cross-head extruder 4 and drawing down the tube 5 on to the optical fibre 1. The latter may be fed into the cross-head 3 directly from a glass drawing apparatus or from a storage reel 2. The optical fibre 1 may be cooled to ambient temperature before entering the crosshead 3. The plastics tube 5 containing, but not in contact with, the fibre 1 may be passed through a cooling trough 6, a primary capstan 7 to a drawing and sizing die 8, a capstan 9 and a storage reel 10. The drawing down may be assisted by heat. The sizing die 8 may be dispensed with. The plastics material may be polyethylene terephthalate.
