Single mode optical fiber |
摘要 |
An optical transmission fiber comprises a central core having an index difference &Dgr;n1 with an outer optical cladding; a first inner cladding having an index difference &Dgr;n2 with the outer cladding; and a second buried inner cladding having an index difference &Dgr;n3 with 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).
