    摘要: A single-mode optical fiber has a cut-off wavelength of 1260 nm or less, a zero-dispersion wavelength in the range of 1300 nm to 1324 nm, a zero-dispersion slope of 0.093 ps/nm 2 /km or less, a mode field diameter at a wavelength of 1310 nm in the range of 5.5 µm to 7.9µm, and a bending loss of 0.5 dB or less at a wavelength of 1550 nm, the bending loss being produced when the fiber is wound around a 10-mm radius for 10 turns.

    摘要: A water penetration-detecting apparatus includes an optical fiber sensor (14) having an optical fiber (16), and a water-­absorbent material (18) disposed along the optical fiber in contiguous relation to the fiber. The water-absorbent material, when absorbing water, expands volumetrically so as to apply a pressure to an outer peripheral surface of the optical fiber to bend the fiber. A detecting means (12) is connected to the optical fiber sensor for detecting a bending of the optical fiber.
