摘要： Adapters for interconnecting optical fiber lines, including optical amplifiers, with optical transmitters and receivers in which the operating parameters of the optical amplifiers are different from the operating parameters of the transmitters and receivers. The adapters convert the optical signals from a transmitter to those within the operating parameters of the optical amplifier and convert the optical signals from an optical amplifier to those within the operating parameters of the receiver. The adapter receiving the optical signals from the transmitter also has provision for inserting service signals and the adapter receiving signals from an optical amplifier has provision for separating the optical signals from the service signals. Also, switching devices for changing transmitters and/or receivers or lines in the event of component failures.

摘要： An optical amplifier for telecommunication lines over which communication signals at a predetermined wavelength are transmitted. The amplifier has portions of two optically coupled fibers, at least one of the fibers being an active fiber, interconnected by a length of active fiber connected to the one fiber of successive portions. Preferably, the active fibers are doped with erbium, and the coupling wavelength of the two fibers is different from the communication signal wavelength so that energy of the spontaneous emission of erbium is transferred from the one fiber to the other fiber and absorbed in the latter permitting amplification of communication signals in a range of wavelengths corresponding to the tolerance range of commercial laser signal emitters.

摘要： The invention relates to an optical amplifier, in particular for optical fiber telecommunication lines (1), operating with a transmission signal in a predetermined wavelength range, which amplifier comprises a fluorescent active optical fiber (6) doped with erbium, having two cores (11 and 12, 101 and 102), one (11, 101) of which is connected to a fiber (4) in which a transmission signal to be amplified and a luminous pumping energy are multiplexed, and to an outgoing fiber adapted to transmit the amplified signal, whereas the second core (12, 102) is optically coupled to the first core and is capable of absorbing the spontaneous erbium emission which would constitute a noise source, allowing a signal to be amplified in a wavelength range substantially corresponding to the tolerance range of the commercially available signal laser emitters.
