High Speed InGaAs Photodiodes

Electro-Optical Characteristics

FCI-InGaAs-XXX series with active area sizes of 75 µm, 120 µm, 300 µm, 400 µm, and 500 µm, exhibit the characteristics and need for Datacom and Telecom applications. Low capacitance, low dark current and high responsivity from 1100 nm to 1620 nm make these devices ideal for high bit rate receivers used in LAN, MAN, WAN, and other high speed communication systems. The photodiodes are packaged in 3 lead isolated TO-46 cans or with AR coated flat windows or micro lenses to enhance coupling efficiency. FCI-InGaAs-XXX series is also offered with FC, SC, ST and SMA receptacles.
