Abstract
The present invention provides an apparatus comprising a passive optical transmission fiber. The passive optical transmission fiber comprises a passive glass fiber core, a glass optical inner cladding surrounding the core and a glass optical outer cladding surrounding the inner cladding. The inner cladding has a lower index of refraction than the passive glass fiber core and the outer cladding has a lower index of refraction than the inner cladding. The passive optical transmission fiber also comprises a second optical segment coupled to the optical fiber. The second optical segment is configured to dissipate light in the inner cladding.
