PD40F8
8 x 56 Gbaud Photodiode Array
PD40F8 is a very high-speed 8-channel InGaAs/InP photodiode array chip with a ground-signal-ground (G-S-G) pad layout and a photodiode channel pitch of 250 µm. The large topside illuminated p-i-n photodiode structures are optimized for 56 Gbaud PAM-4 (800GBASE-DR8) single-mode telecom, microwave photonic and RF over fiber links, as well as test and measurement applications.
The compact photodiode array offers excellent responsivity and high speed of response.
