4 x 56 Gbaud GaAs Photodiode Array

Ultra high-speed short-wavelength 4-channel GaAs photodiode array with ground-signal-ground (GSG) pad layout. The large optical apertures and the photodiode pitch of 250 µm are ideal for coupling to fiber ribbon cables. The topside illuminated p-i-n photodiode structures are optimized for 56 Gbaud telecom and 400GBASE-SR4 data center applications.
