Functional Description
This PIN-preamplifier module is a low-cost capable receiver module with a miniature size for use in
the 10Gb/s SONET/SDH systems. A Back-illuminated pin-photodiode has a monolithic lens optimized for
SM fiber at the InP substrate and achieves high responsivity, wide-tolerance and high-speed. The
component of a high-speed and low-noise preamplifier and the photodiode obtains high sensitivity and a
stable operation. The high performance butterfly package was developed for high-speed operation, small
dimension and low cost.
The module is applicable for 1.31µm/1.55µm optical fiber communication systems for
OC-192/STM64, typically showing a high sensitivity of –19dBm.
