The GX62472 is a high-performance parallel low Vpi Mach-Zender Modulator (MZM) driver designed for 100G DP-CQPSK long-haul optical transmitters. The GX62472 is a Small Form Factor (SFF) differential inputs single ended output Coplanar/GPPO packaged solution consisting of 4 x 32G broadband amplifiers, each capable of driving a linear output voltage of 6Vpp suitable for multilevel modulation applications. The GX62472’s GPPO full detent output connectors have been designed to be snap-in compatible with SMI’s 100G GPPO gearbox and the OIF 100G modulator standard proposal. The GX62472’s input coplanar interface has been designed according to OIFDPC-RX-01.0 standard.
