ABSTRACT:
Optical fibers and optical transmission systems, which are capable of broadband and large capacity single-mode optical transmission, and have low macrobends are provided.The optical fiber made from pure silica comprising a core region, a cladding region at the circumference of the core region a coating layer made from a resin at the circumference of the cladding region, and having a cutoff wavelength of shorter than 1530 nm, and positive dispersion at 1550 nm, bending loss of less than 10 dB/m at a bending diameter of 20 mm, and an effective core area of 120 μm2.
