DQPSK Optical Modulator, 2 x 12 Gb/s (DQPSK-OM-12)

Data Sheet

Product Overview

The Optilab Dual Quadrature Phase Shift Keying (DQPSK) modulator design is based on a dual parallel structure of two Mach-Zehnder modulators embedded in a Mach-Zehnder super-structure. Each internal modulator is designed to support 12 Gb/s signals. An integrated polarizer enables high extinction ratios as required for the DQPSK modulation format. Contact Optilab for more information.
