ABSTRACT:
An optical transmission fiber includes a central core having an index difference Δn1with an outer optical cladding; a first inner cladding having an index difference Δn2with the outer cladding; and a second buried inner cladding having an index difference Δn3with the outer cladding of less than −3.10−3. The second buried inner cladding moreover contains Germanium in a weight concentration of between 0.5% and 7%. The fiber shows reduced bending and microbending losses whilst exhibiting the optical performances of a standard single-mode fiber (SSMF).
