NeoPhotonics Corporation (NYSE: NPTN), a leading designer and manufacturer of photonic integrated circuit, or PIC, based modules and subsystems for bandwidth-intensive, high speed communications networks, today announced that its PIC-based small form factor DQPSK demodulator, designed for use in 40Gbps direct detection fiber optic transport systems, is now ramped to volume production. The small form factor version is less than half the size of the standard form factor DQPSK demodulator and saves precious board space in high capacity systems.
