The GainNet M8 multiport amplifier combines eight integrated amplifiers in a single package, sharing common pump lasers. The amplifier provides gain for eight independent signals (i.e., eight cable-TV streams, eight 32-channel DWDM signals, or eight individual DWDM channels), and delivers up to 1 W of output power. The GainNet M8 can be used in different configurations, including an "eight-in-one" parallel mode, where eight independent amplifiers can connect to as many as eight optical-fiber cables, each carrying WDM bit streams. The amplifier also can incorporate components such as gain-flattening and dispersion-compensating filters.
