Digital Drivers
Quick Overview
The DR-DG family is a set of modulator driver modules specially designed for telecommunication modulation formats such as NRZ, RZ up to 44 Gb/s, DPSK up to 28 Gb/s, and 22 Gb/s (D)QPSK up to 2 x 28 Gb/s.
The DR-DG RF amplifiers are generally mandatory to amplify the electrical signal delivered by a PRBS (Pseudo Random Bit Sequence) or an AWG (Arbitrary Waveform Generator) generators so as to reach the optimum amplitude before applying it to the modulator RF port.
The DR-DG drivers are key components to obtain high quality eye diagrams with high SNR, low jitter and fast rise and fall times. They operate from a single power supply for safety and ease of use, and offer gain control.
The DR-DG modulator drivers come in a compact connectorized module that match (mechanically and impedance) directly with exail phase and intensity modulators.
