HAMAMATSU G8795-02, G8795, G8341-02, G8341, G8338-02 Datasheet

PHOTODIODE

InGaAs PIN photodiode with preamp

G8338/G8341/G7871/G8795 series

TO-18 package, 1.3/1.55 mm, 156, 622 Mbps/1.25, 2.5 Gbps

G8338/G8341/G7871/G8795 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 integrated with a high-speed preamp, allowing easy
connection to a latter-stage circuit. Lens window types are also available for efficient and easy coupling to an optical fiber.
