Abstract :
The pressure-induced retardation in a sample of single-mode fibre cable has been measured. The pressure sensitivity of the uncoated fibre was found to agree with the theoretically expected value. Application of a silicone rubber coating reduced the sensitivity by over 50%. No pressure sensitivity was measured when a loose-fitting tube was extruded around the coated fibre.
