PHOTODIODE
InGaAs PIN photodiode with preamp
G8340/G8343/G8211/G8797 series
Pigtail type, 1.3/1.55 µm, 156, 622 Mbps/1.25, 2.5 Gbps
G8340/G8343/G8211/G8797 series are high-speed receivers specifically developed for 1.3/1.55 µm band optical fiber communications.
These devices incorporate a high-speed, high-sensitivity InGaAs PIN photodiode and a high-speed preamp integrated in a pigtail
module. Packages are available with various connectors and mounting styles.
