InGaAs PIN photodiodes with preamp
G9822 series
Pigtail type, 1.3/1.55 μm, 2.5 Gbps
The G9822 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 and a high-speed preamp
integrated in a pigtail module.

*1: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation
may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product
within the absolute maximum ratings.
