摘要： A construction of gain tilt exhibiting optical amplifier that incorporates a gain flattening filter also includes a neutral density filter the value of whose attenuation is adjustable after assembly of the components of the amplifier. This neutral density filter is constructed by the performance of a succession of localised re-fusion operations at a localised region of an optical fiber. By this means the attenuation is increased to a desired value that provides the amplifier with optimised gain flattening at some predetermined value of amplifier external gain.

摘要： A variable gain optical amplifier comprises an EDFA for amplifying optical signals at different wavelengths and a pump driver 14 for optically pumping the EDFA to provide optical gain. An input detector 2 is provided for monitoring the power Pin of input signals to the EDFA, and an output detector 3 is provided for monitoring the power Pout of output signals from the EDFA. A gain control arrangement is provided for supplying a drive signal to the pump driver 14 to control the optical gain including a feed forward arrangement 20, 21, 22, 23 for supplying a feed forward signal dependent on the monitored input power Pin, and a feed back arrangement 5, 6, 7, 8, 9, 30 for supplying a feed back signal dependent on the monitored output power Pout. In order to ensure rapid gain control the feed back arrangement comprises an adaptive proportional-integral (PI or PID) controller 30 for controlling the optical gain at a required gain set point in accordance with proportional and integral control coefficients Kp and Ki corresponding to a required gain profile, at least one of which is dynamically variable in dependence on the monitored output power Pout, the output signal from the controller 30 and the feed forward signal being added in an adder 31 to produce the drive signal for the pump driver 14.

摘要： In a WDM optical transmission system employing optical amplifiers in its transmission path, a supervisory signal channel, used for monitoring and controlling the operation of the amplifiers and spectrally separated from the data transmission, may be multiplexed with the data. A construction of amplifier is disclosed which is capable of being upgraded with an upgrade of the transmission system to include additional data handling capacity, for instance data transmission in an additional waveband and/or in the opposite direction, without interruption of the pre-upgrade data transmission path through the amplifiers. This is accomplished by the use of channel dropping and insertion filters disposed so that the amplifying data transmission path extends via the drop/insertion channel of those filters.

摘要： An optical amplifier comprises a pumped doped fiber with a power measurement circuit for measuring the input and output power of the amplifier. Automatic gain control is implemented, and the calculation of output power for the AGC loop takes into consideration the temperature provided by a temperature measurement device. This enables a flatter gain response to be achieved over varying input power, which enables an increase in the dynamic range of the amplifier and thereby a possible increase in system capacity of a WDM system using the amplifier.
