摘要： An optical fiber polarization mode dispersion measurement method includes a step of inputting a pulse light subjected to a single rectilinear polarization to an optical fiber to be measured, a step of isolating the single rectilinear polarization from the backward scattering light by the input pulse light, a step of detecting the light intensity as time series data from pulse light generation, a step of calculating irregularities of the light intensity in the time series data, and a step of evaluating the polarized mode dispersion of the optical fiber to be measured.

摘要： A polarization preserving optical fiber having excellent polarization preserving characteristics even if a clad diameter is reduced to about 80 mum, and incurring a very small connection loss when connected to an optical fiber having a clad diameter of 125 mum. The polarization preserving optical fiber comprises a core; a pair of stress imparting units provided in the outer radial direction of the core; and a clad surrounding the core and the stress imparting units. Setting the diameters D of respective stress imparting units to 21-32 mum, an interval R between the stress imparting units (2, 2) to 6-17 mum, and a relative refractive index difference Delta between the core and the clad to 0.3-0.5% can ensure a sufficiently large mold field diameter (MFD) and reduce a connection loss.

摘要： A dispersion compensating optical fiber that does not cause a loss increase even if wound on a small reel and that has stabilized temperature characteristics. A dispersion compensating optical fiber is formed that, at at least one wavelength of 1.53 - 1.63 mum, has a bending loss of 5 dB/m or less for a bending diameter of 20 mm, a wavelength dispersion of -120 ps/nm/km or less, a cut-off wavelength of 1. 53 mum or less in the state of use, a clad outer diameter of 80 - 100 mum, a coating outer diameter of 160-200 mum, and a coating resin surface stickiness of 10 gf/mm or less. Set b/a at 1.5 - 3.5, c/b at 1.2 - 2.0, a core radius at 4 - 8 mum, DELTA1 at +1.6% - +2.6%, DELTA2 at 0.30 % - 1.4 %, and DELTA3 at 0.30% - +1.0%. Set the Young's modulus of the primary coating layer at 0.15 kgf/mm2 or less and its thickness at 20 - 30 mum, and the Young's modulus of the secondary coating layer at 50 kgf/mm2 or more and its thickness at 15 - 30 mum.
