Optical amplifiers are best suited for shorter transmission distances between the transmitter and receiver. An optical repeater receives the optical signal and converts it into an electrical signal. Such repeaters are used to extend the reach of optical communications links by overcoming loss due to attenuation of the optical fiber.

However, when considering higher frequency effects, it would be wrong to assume the input impedance remains zero at higher frequencies because it. When a large impedance is combined with even a tiny amount of capacitance, the result is a large τ. The basic op-amp transimpedance amplifier looks like this, with the op-amp's non-inverting (+) input grounded, and a feedback resistor Rfbetween inverting (-) input and output: The input current flows entirely through the feedback resistor, and the op-amp adjusts its voltage output to keep its inputs at equal voltages. From the perspective of Kirchhoff's Current Law at the op-amp's inverting input node, it is indistinguishable as to whether the current contribution comes from a resistor VinRin=iin (from the previous op-amp inverting amplifier section) or simply from an externally-specified input current iinas in the transimpedance amplifier. A voltage-controlled voltage source (VCVS) model lets us examine more fine-grained behavior of the transimpedance amplifier and its limitations. As we did in the inverting amplifiersection, we'll replace the ideal op-amp with a VCVS model.
