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.

*1: G8338/G8341 series cannot be operated with RL=50 Ω, so they should be used with a load resistance larger than 500ɹΩ.
*2: Single ended (Vout+) measurement.
*3: G8338/G8341 series: Pin= -30 dBm
G7871 series: Pin= -22 dBm
G8795 series: Pin= -17 dBm
