DESCRIPTION
The FID3S2KX is a PIN photodiode module with a single mode fiber pigtail specifically
designed for multichannel analog transmission systems. The photodiode uses a planar
structure to achieve low dark current, high responsivity and high reliability. The coupling optics
in the package is designed for very low optical reflection. The package is hermetically sealed.
