PIN Photodiode FID3Z2KX/LX
FEATURES
• Data rates up to 2.5 Gb/s
• High Quantum Efficiency: 0.8A/W at 1,310nm
• Low dark current: 0.1nA
• Photosensitive area: 50µm diameter
• Wide spectral response range: 900nm to 1,600nm
APPLICATIONS
• Optical transmission system: STM-1 (OC-3),
STM-4 (OC-12) or STM-16 (OC-48) short haul.
DESCRIPTION
The FID3Z2KX/LX is a PIN photodiode with a multimode
fiber pigtail designed for use in local area network, subscriber loop
and high bit-rate tranmission system applications up to 2.5 Gb/s at
both 1,310nm and 1,550nm wavelength. The PIN chip has a
photosensitivity area diameter of 50µm with a planar structure and
guardring for high reliability. A multimode fiber is aligned to the
hermetically sealed PIN diode. The optical alignment system has
the high coupling stability.
