摘要: A multimode optical fiber includes a central core and an outer cladding (e.g., an outer optical cladding). Typically, the optical fiber's central core is a depressed, central core having an alpha-index profile (i.e., a graded-index profile), an outer radius r1, and a maximum refractive index difference Δn1 with respect to the outer cladding. The central core's alpha-index profile has a minimum refractive index at the central core's outer radius r1 that corresponds to a refractive index difference Δnend with respect to the outer cladding. Exemplary optical-fiber embodiments may include an inner cladding having an outer radius r2 and a width w2. Exemplary optical-fiber embodiments may include a buried trench having a width w3 and an outer radius r3. Furthermore, exemplary optical-fiber embodiments may include an intermediate cladding having an outer radius r4 and a width w4.

摘要: A treatment method for an optical fibre including the steps of exposing the fibre to an atmosphere containing deuterium at a given temperature, concentration and pressure, measuring the attenuation in the fibre as a function of time at least one wavelength, during the exposure of the fibre to an atmosphere containing deuterium, identifying an attenuation maximum after an exposure duration, and stopping the exposure of the fibre to the atmosphere containing deuterium when said duration has elapsed.
