G8338/G8341/G7871/G8795 series are high-speed receivers specifically developed for 1.3/1.55
m 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.
