OSI Optoelectronics' FCI-125G family of large active area and high-speed silicon PIN photodiodes possesses a large sensing area optimized for short-haul optical data communication applications at 850 nm. The photodetectors exhibit high responsivity, wide bandwidth, low dark current and low capacitance at 3.3 V. They are designed to match the most widely used transimpedance amplifiers.

The photodiodes can be used in all 850 nm transceivers and GBICs up to 1.25 Gbps applications such as Gigabit Ethernet and Fibre Channel. The chip is isolated in a 3-pin TO-46 package with options of micro lens cap or an AR coated flat window. They are also available in standard fiber receptacles such as FC, ST, SC and SMA. For availability in chip form please contact AMS Technologies.
