Patent ID: 8811789

Claim:
An optical transmission system, comprising: a transmitter; a receiver; an optical transmission fiber coupling said transmitter to said receiver, said optical transmission fiber including: a core having a first index of refraction; a cladding material located around said core and having a second index of refraction that is less than said first index of refraction; and a first coating material located around a first portion of said cladding material and having a third index of refraction that is greater than said second index of refraction, and a second coating material located around a second portion of said cladding material and having a fourth index of refraction less than said second index of refraction, said second coating material substantially confining light energy escaping from said core within said second portion of said cladding material for transmission to an energy removal location; and an energy removal device coupled to said coating material and configured to remove energy from said optical transmission fiber at said energy removal location.
