    • Opto-electronic measuring arrangement which is largely independent of extraneous light, comprising an emitted light source (2, 102) and a compensation light source (3, 103), which emit light time-sequentially and in a phased manner, wherein the emitted light is phase-shifted respectively by 180°. An optical receiver (4), equipped with a receiver diode (5, 104), receives the light emitted by the emitted light source (2, 102) and reflected (13) by the object being measured, said light containing a measuring signal, together with the light from the compensation light source (3, 103). In a control unit, the actuation signals for the emitted light source (2, 102) and the compensation light source (3, 103) are controlled in such a way that the synchronous signal difference occurring in the receiver (4) between the different phases is reduced to zero. The optical coupling between the compensation light source (3, 103) and the receiver diode (5, 104) occurs mainly via an optical system in a printed circuit board (101) of the measuring arrangement (1), on which the compensation light source (3, 103) and the receiver (4, 104) are arranged. In the simplest and most important realisation, the printed circuit board itself, i.e. the FR4 component thereof, constitutes the optical conductor between compensation light source (3, 103) and receiver diode (5, 104).

    • A method of controlling gain of a fiber amplifier and a device utilizing same, employing a digital component to replace a conventional closed-loop analog control unit, and computing, according to gain or a configuration of an optical output power in combination with an amplified spontaneous emission (ASE) compensation power, on the basis of a present control mode, a final optical output power. The method comprises: smoothing an optical input power so as to remove a discrete frequency noise, while providing certain compensation to an input signal. The embodiments of the present invention enhances performance of a system by adopting a derivative control algorithm and an integral control algorithm, enabling a closed-loop control system to complete a control cycle in substantially 1 µs, effectively realizing a gain lock and power lock, meeting dynamic and steady state indicators provided by a user, addressing an issue in which a fiber amplifier does not have high-accuracy ASE compensation, and employs a low-speed derivative control, thereby increasing accuracy of ASE compensation and a speed of a derivative control.
