Model H301
10 Gb/s Optical Modulator
Driver
Product Bulletin
Preliminary
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 Vpp drive levels. The
flat gain and flat group delay response yield a high-
quality, 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.
