The H301 optical modulator driver provides a high-quality, single-ended voltage to drive an external laser modulator. Typical applications include driving EML, EAM, and Mach-Zehnder style modulators. It amplifies 2.488 to 12.2 Gb/s data input signals to >7.0 Vp-p drive levels. The flat gain and flat group delay response yield a highquality, low-jitter electrical drive signal. The driver meets applicable SONET and SDH standards for OC-192 10 Gb/s optical transmitters and includes reference and detector outputs to enable external temperature-compensated control of output drive levels. The module has field replaceable input and output K-connectors for the input/output drive signals and an eight-pin connector for the detector, reference, and power interfaces.
