InGaAs PIN photodiodes
G9801 series
Receptacle type, 1.3/1.55 μm, 2 GHz
The G9801 series are high-speed receivers specifically developed for 1.3/1.55 μm band power monitor in optical fiber com-
munications. These devices incorporate a high-speed, high-sensitivity InGaAs PIN photodiode integrated in a receptacle
module. Packages are available with various connectors and mount types.

*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.
