摘要： An apparatus for manufacturing a depressed cladding ultra-low water peak optical fiber core rod and a method thereof. The synthesized core rod has a complex refractive index profile. The apparatus comprises a core rod component, a sleeve component, a high-temperature heat source (8), chucks (9), a rotary joint (10), an external air supply pipeline (11) and a pressure control pipe (12). The core rod component is formed by melting and butting a core layer rod (5) and a core rod hollow handle (4). Several vents are drilled at one end, near the core layer rod (5), of the core rod hollow handle (4). The sleeve component is formed by melting and butting an inner cladding sleeve (6) and a sleeve hollow handle (7). The inner cladding sleeve (6) of the sleeve component is sleeved on an outside of the core layer rod (5) of the core rod component. The core rod hollow handle (4) of the core rod component and the sleeve hollow handle (7) are clamped in two chucks (9) of a glass lathe respectively. An outer end of the core rod hollow handle (4) is connected to the external air supply pipeline (11) through the rotary joint (10). The high-temperature heat source (8) is arranged outside the inner cladding sleeve (6).

摘要： A single-mode optical waveguide fiber designed to limit power penalty due to four wave mixing and a method of making the waveguide is disclosed. Variations in properties, e.g., radius or refractive index, of the waveguide fiber core provide a total dispersion which varies along the length of the waveguide. The algebraic sum of products of length times total dispersion is controlled to a pre-selected value for each waveguide fiber which makes up a system link. Proper choice of total dispersion variation magnitude and sub-length results in a system link wherein a signal travels only short distances in waveguide portions having total dispersion near zero. However, the variation of the total dispersion provides a system link which has a pre-selected dispersive effect on the signal over a selected wavelength range. The dispersive effect on the signal can be chosen to be essentially zero. A number of techniques for fabricating DM fiber are also disclosed.
