The Model FO-MDA-20-25DD-1 (from Narda), a dual-channel DQPSK modulator driver for 40-Gb/s and 100-Gb/s optical transponder applications, has a maximum data rate of 35 Gb/s, and has been tested at rates as high as 113 Gb/s. It is designed to interface with a Sierra Monolithics SMI 4025 DQPSK multiplexer/clock multiplier unit on the input and an Avanex Mach-Zehnder lithium-niobate MZ DQPSK modulator at its output. It integrates a separate channel for I and Q signals within its 36 mm x 28 mm x 8 mm package and uses GPPO connectors. The FO-MDA-20-25DD-1 has 30 dB of gain per channel, and output of more than 8 Vpp.
