An optical receiver includes a reverse biassed photodiode whose output is coupled to a transimpedance amplifier. A load impedance for the photodiode comprises a forward biassed semiconductor diode, enabling the photodiode to be biassed using a low voltage supply. A signal compressing arrangement can be provided between the transimpedance amplifier output and the semiconductor diode on the side thereof remote from the photodiode. The transimpedance amplifier can have a capacitive transimpedance element; a filter, including an open circuit transmission line, is described which is coupled to the output of such an optical receiver to provide a desirable form of optical receiver arrangement. The capacitive transimpedance element can be constituted by a capacitance of the photodiode.
