| titleOfInvention | Fiber optic repeater |
| abstract | Repeater amplifier in which a diode laser (20) or a light-emitting diode are coupled to a fiber link in order to activate the latter and in order to obtain a positive gain, the link comprising a certain length (12) of the transmission line of neodymium or erbium doped optical fiber. The present invention also relates to an improved transmission line, in which the line is effectively formed as a continuous repeater amplifier by doping the line of the optical fiber with an amount of neodymium or erbium barely sufficient to erase line losses of optical signals transmitted along said line. The typical operating wavelengths of the diode laser are 700 to 900nm. One of the advantages found in the present invention consists in using a support for light signals of 1.318 microns for doping with neodymium and 1.54 microns for doping with erbium. |
