Alcatel 1902 OFA
Booster amplifier with integrated electronics
Erbium-Doped Fiber Amplifier
Description
The Alcatel 1902 OFA products belong to the
Alcatel 1900 OFA family of Optical Fiber
Amplifier (OFA) modules, designed for the third
telecommunica-tion window (1550 nm). Using
reliability proven high power 1480 nm lasers
and optimized Erbium-Doped Fiber, they
provide high gain, high output power and low
noise amplification. They incorporate a very
high degree of integration and are presented in
a compact package with connectorized pigtails.
The modules may be mounted directly into a PC
board and are, thus, ideal for optimization of
system size. The integrated electronics provide
an easy user digital interface, exempting the
designer from input & output signal controls.
The output power is kept constant through on
APC (Automatic Power Control) loop, and the
chip temperature is stabilized at + 25 ± 10 °C
with an ATC (Automatic Temperature Control)
loop.
Five alarms are generated by the modules: loss
of input signal, loss of output signal, output
power degradation, laser over down circuitries
are set up in the electronic's module : automatic
shut clown (the output power is switched off if
there is no input power or if the temperature is
out of range), and external shut down
command.
