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 and offer an excellent responsivity and high speed of response in the wavelength range from 830 to 860 nm.
- Large bandwidth: 26 GHz per channel
- Photodiode pitch: 250 µm
- High responsivity: > 0.5 A/W @ 850 nm
- Low dark current: 0.1 nA
- G-S-G pad configuration for each channel
