| Analog PIN Photodiode FEATURES * * * * * * PIN photodiode for CATV/Analog applications High Responsivity Wide Bandwidth Low Modulation Distortion High Optical Return Loss: >40dB High Frequency Response: >2.5GHz FID3S2KX APPLICATIONS * Analog Transmission Systems * AM and FM CATV systems 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.
