Low bend loss optical fiber and components made therefrom

摘要

The present invention provides an optical fiber suitable for the manufacture of optical fiber couplers and having low bend loss, low splice loss, and low attenuation. The optical fibers according to one aspect of the invention have bending loss of less than 0.5 dB at 1560 nm when wrapped 5 turns around a 20 mm mandrel; and an average fiber pull test loss of less than 0.1 dB in the wavelength range of 1530 nm to 1550 nm. The present invention also includes optical fiber components made from these optical fibers.
