Abstract
A method and apparatus for monitoring an electrical property of a conductive coating on an optical fiber, the method comprising capacitively coupling at least one alternating electrical signal into and out of the conductive coating and measuring an electrical property of the coating carrying the alternating electrical signal. The apparatus comprises generating means for generating an alternating electrical signal; capacitive coupling means for capacitively coupling the alternating electrical signal into and out of the conductive coating, the capacitive coupling means being electrically connected to the generating means; and measuring means for measuring an electrical property of the conductive coating carrying the alternating electrical signal, the measuring means being electrically connected to the capacitive coupling means. A method of manufacturing coated optical fiber which incorporates the method of monitoring an electrical property of a conductive coating is also disclosed.
