DESCRIPTION
The FID3Z1KX/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
guard ring for high reliability. A multimode fiber is aligned to the
hermetically sealed PIN diode. The optical alignment system has the
high coupling stability.
