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.
