G10476 series is a family of 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.
