♦ Functional Description
The F083 series PIN-preamplifier modules are low-cost capable receiver modules with a
miniaturized size for use in the standard SONET/SDH systems. The most remarkable fea-
ture is its low voltage operation of 3.3 V, which is very convenient for a combination with 3.3
V-chip sets. For the F081 series PIN-Amplifier modules, the InP pin-photodiode (PD) with
monolithically integrated resistors and capacitors is utilized to spontaneously achieve excel-
lent noise immunity with a large dynamic range. The PD technology which enables high-
speed operation even with a low bias voltage and the GaAs circuit technology with a low
voltage operation are applied to achieve high sensitivity and a stable operation with the
single 3.3 V power supply. Differential outputs and photocurrent monitoring functions are
available with the 5-lead TO-18 package.
