Abstract:
1. An optical-fiber cable, comprising: a plurality of multimode optical fibers, said multimode optical fibers complying with the ITU-T G.651.1 recommendations; a plurality of strength yarns, at least one of said strength yarns being lubricated; and a cable jacket surrounding said multimode optical fibers and said strength yarns, said cable jacket having an outer diameter of no more than about 3.2 millimeters; wherein the optical-fiber cable has an inner cable filling coefficient of at least about 0.15; wherein, as measured on a drum having a diameter of about 250 millimeters, the optical-fiber cable has a maximum attenuation of less than about 3.5 dB/km at a wavelength of 850 nanometers and less than about 1.5 dB/km at a wavelength of 1300 nanometers; wherein, as measured in accordance with the FOTP-3 procedure, the optical-fiber cable has a maximum increase in attenuation of less than about 0.60 dB/km at a wavelength of 1300 nanometers using a minimum temperature of about 0° C. and a maximum temperature of about 70° C.; and wherein, as measured under a compressive load of about 20 lb/in and in accordance with the FOTP-41 procedure, the optical-fiber cable has a maximum increase in attenuation of less than about 0.60 dB at a wavelength of 1300 nanometers.
