ABSTRACT:
On line coating of optical fibre (20) adopts silicon nitride or oxynitride to provide an hermetic seal using chemical vapor deposition. Non-contacting gas seals (3,4) at the top and bottom of the reaction chamber are so constructed that fibre vibration is avoided, (6) surface flaws are minimized and the coating minimizes stress corrosion.
