Innovative measurement technique for characterizing electro-optical components

Anritsu has developed a technique for its family of Lightning Vector Network Analyzers (VNA) to enable the measurement of domain-transfer devices such as optical modulators, integrated transmitters, photodiodes and photo-receivers. The technique facilitates the measurement of electrical to optical (E/O) and optical to electrical (O/E) transfer function in terms of bandwidth, flatness and phase linearity (group delay) and, with frequency coverage to 65 GHz, is ideally suited for characterizing devices used in 2.5, 10 and 40 Gb/s transmission systems.
