Abstract
An integrated high speed driver/modulator assembly includes a driver amplifier assembly having a specified input impedance, such as 50 ohms. The driver/modulator assembly also includes an optical modulator having a modulator transmission line. The impedance of the modulator transmission line is less than the specified input impedance, which results in a reduced V&pgr; for the optical modulator. The reduction in V&pgr; enables the driver/modulator assembly to more effectively support OC-768 and higher data rates of at least 40 Gb/s.
