DESCRIPTION
Hybrid high dynamic range optical receiver amplifier
module in a SOT115T package. Two of the module pins
are for connection to 24 V (DC), one for amplifier supply
voltage and the other for the pin diode bias.
The module contains a monomode optical input suitable
for wavelengths from 1290 to 1600 nm, a terminal to
monitor the pin diode current and an electrical output with
an impedance of 75 Ω.
