Description:
The DSC-R409 is a linear and versatile PIN + transimpedance amplifier suited for a variety of digital and analog applications. The R409 offers a linear response to > 0dBm optical input, +4dBm of optical overload at 40Gb/s, 30GHz of RF bandwidth and a conversion gain of 300 V/W. Its linearity and well-controlled frequency response results in excellent system-level performance for both digital and analog applications.The R409 is available as a fiber optic module with differential GPPO RF outputs or as a Lab Buddy instrument, both of which utilize Discovery's high reliability InGaAs photodiode technology.
The R409 Lab Buddy is also available with an option 25-28 Gb/s clock and data recovery (CDR) unit. The unit conveniently interfaces with the bit error rate (BER) test stations and provide a 3R (Receive, Reshape & Retime) solution, which is especially important for transmission experiments. The CDR also incorporates a programmable input equalization filter that can be adjusted for optimum link performance using an included GUI control program.
