| 20090185780 | Fluorine-Doped Optical Fiber - A single mode optical transmission fiber comprises a depressed core having at least 0.41 weight percent fluorine and an index difference (|Δn | 07-23-2009 |
| 20100021117 | Single-Mode Optical Fiber - Disclosed is an optical transmission fiber having reduced bending and microbending losses that is commercially usable in FTTH or FTTC transmission systems. | 01-28-2010 |
| 20100067859 | Single Mode Optical Fiber - An optical transmission fiber comprises a central core having an index difference Δn | 03-18-2010 |
| 20100189398 | Optical Fiber Preform - An optical fiber preform comprises a primary preform that includes at least one inner cladding and a central core deposited inside a fluorine doped silica tube. The fluorine doped silica tube has a cross section area that is no more than about 15 percent smaller than the cross section area of the primary preform. The optical fiber preform has a large capacity, may be manufactured at reduced cost, and may be drawn to produce an optical fiber having reduced transmission losses. | 07-29-2010 |
| 20100189928 | Method for Manufacturing an Optical Fiber Preform - A method for manufacturing an optical fiber preform includes the steps of depositing an inner cladding and a central core inside a fluorine doped silica tube and thereafter collapsing the silica tube to form a primary preform. The fluorine doped silica tube has a cross section area that is no more than about 15 percent smaller than the cross section area of the resulting primary preform. The present method facilitates reduced-cost manufacturing of a high-capacity optical fiber preform, which may be drawn to produce an optical fiber having reduced transmission losses. | 07-29-2010 |
| 20100251775 | DEUTERIUM TREATMENT METHOD FOR OPTICAL FIBRES - A treatment method for an optical fibre including the steps of exposing the fibre to an atmosphere containing deuterium at a given temperature, concentration and pressure, measuring the attenuation in the fibre as a function of time at least one wavelength, during the exposure of the fibre to an atmosphere containing deuterium, identifying an attenuation maximum after an exposure duration, and stopping the exposure of the fibre to the atmosphere containing deuterium when said duration has elapsed. | 10-07-2010 |
| 20110164852 | Single-Mode Optical Fiber - Disclosed is an optical transmission fiber having reduced bending and microbending losses that is commercially usable in FTTH or FTTC transmission systems. | 07-07-2011 |
| 20110286710 | Single Mode Optical Fiber - An optical transmission fiber comprises a central core having an index difference Δn | 11-24-2011 |
