摘要： An optical amplifier system is provided which comprises first and second optical amplifiers (1, 2) for amplifying optical signals in a fibre optic communications link and a common pump (3) for optically pumping both the first amplifier (1) and the second amplifier (2) to effect such amplification. There is also provided an optical switch (6) for providing an optical path between the pump and the first amplifier in a first switching state and an optical path between the pump and the second amplifier in a second switching state to enable pumping of the first and second amplifiers by the pump sequentially. Advantageously this arrangement provides high accuracy to the outputs (4, 5) of the pump (3) and reduces low power pump noise.

摘要： An optical amplifier comprises an optical fibre, a pump laser for optically pumping the optical fibre to amplify an optical signal, a TEC 1 for cooling the pump laser on receipt of a cooling current, a temperature sensor 2 for monitoring the temperature of the amplifier housing; and a control circuit 3 for controlling the cooling current in dependence on a sensing output from the temperature sensor 2, so as to maintain the temperature of the pump laser at a temperature set point. The control circuit 3 is configured (i) to maintain the temperature of the pump laser at a first temperature set point within a predetermined temperature range of the amplifier, and (ii) to maintain the temperature of the pump laser at a second temperature set point, higher than the first temperature set point, when the sensing output from the temperature sensor 2 exceeds a threshold value. The feature that the temperature set point is raised to a higher level when the temperature of the pump laser goes above a preset level reduces the amount of self-heating of the pump laser, and thus prevents a thermal runaway situation.
