摘要： A dispersion compensating optical fiber is connected to an optical fiber having chromatic dispersion at a transmission wavelength to cancel the chromatic dispersion out, thereby making the chromatic dispersion of an entire transmission system at the transmission wavelength substantially zero or making the chromatic dispersion close to zero. The dispersion compensating optical fiber comprises a core consisting of a quartz-based glass and a cladding formed on the surface of the core and consisting of a quartz-based glass, and a coating layer formed on the surface of the cladding and consisting of a resin, and the dispersion compensating optical fiber has an outer diameter of less than 250 .mu.m. The coating layer has a thickness of 20 .mu.m or more and a two-layer structure consisting of at least two layers including an inner layer and an outer layer having a Young's modulus higher than that of the inner layer.

摘要： A single mode optical waveguide fiber having low, non-zero dispersion over a pre-selected wavelength range is disclosed. The refractive index profile of the core is characterized in that the core includes a plurality of distinct regions, each having an index profile, and a radius or width. By adjusting the index profile sizes and shapes of the plurality of core regions, a waveguide fiber may be made having a set of properties tailored for a high performance telecommunication system. In particular, dispersion slope can be maintained less than 0.05 ps/nm.sup.2 -km and absolute magnitude of total dispersion maintained in the range of 0.5 to 3.5 ps/nm-km over a pre-selected wavelength range. The zero dispersion wavelength is outside the pre-selected wavelength range and the cut off wavelength and mode field diameter are controlled to target values.

摘要： A fiber includes a core and cladding, both of which may have temperature dependent indices of refraction. The materials and size of the core and cladding may be selected such that as the temperature of the core and/or cladding is heated above room temperature, the fiber transitions from supporting multimode optical waveguiding to supporting single mode waveguiding.

摘要： The optical fiber includes a glass fiber and a coating resin layer. The coating resin layer includes a primary resin layer and a secondary resin layer. The glass fiber has an outer diameter of from 124 μm to 126 μm. The secondary resin layer has an outer diameter of from 145 μm to 170 μm. The primary resin layer has an in situ elastic modulus of from 0.1 MPa to 0.5 MPa. The secondary resin layer has an in situ elastic modulus of from 1200 MPa to 2800 MPa. A maximum value of amplitude of an amount of eccentricity is 6 μm or less in a spectrum obtained by measuring the amount of eccentricity of the glass fiber and by applying Fourier transform to a waveform representing the amount of eccentricity.
