METHOD OF MANUFACTURE OF THE OPTICAL FIBERS INTENDED FOR THE HIGH-SPEED DATA TRANSMISSION Russian patent published in 2006 - IPC C03B37/18 

FIELD: glass industry; methods of production of the optical fibers used for the high-speed data transmission.

SUBSTANCE: the invention is pertaining to the field of glass industry, in particular, to the method of manufacture of the optical fibers used for the high-speed data transmission. The method includes the following stages: i) feeding of one or several source substances for production of the glass and possibly the additive compound in the quartz tube-substrate; ii) creation of the plasma in the quart tube-substrate for provision of the reaction in the chemically active mixture for production of the glass layers, which may include or not include the additive compound on the internal side of the tube-substrate; iii) the collapse of the tube-substrate produced at the stage ii) into the billet at heating; iv) drawing the optical fiber from the billet at heating. The glass layers are settled on the section having the greatest diameter of 10 microns in the center of the drawn optical fiber. At least one of the indicated layers has the greatest area of the surface of 2 micron², and the value of the index of refraction inside each layer is increasing in the direction to the center of the fiber. The technical result of the invention is development of the optical fiber capable to transmit information with the speed exceeding 1 Gigabit per a second.

EFFECT: the invention ensures development of the optical fiber capable to transmit the data with the speed exceeding 1 gigabit per a second.
