| Analog PIN Photodiode FEATURES * Hermetically Sealed Package with a single mode fiber pigtail * High Responsivity: 0.85 A/W * Low Dark Current: 0.1 nA * Low Distortion: < -75dBc * High Optical Return Loss: > 40dB * High Frequency Response: 2.0GHz FID3S1HX/KX HX APPLICATIONS * Analog Transmission Systems * AM and FM CATV systems KX DESCRIPTION The FID3S1HX/KX are PIN photodiode modules 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.
