With its new core composition, the IsoGain erbium-doped fiber delivers excellent spectral flatness and high efficiency in high-channel-count DWDM erbium-doped fiber amplifiers (EDFAs)—maximizing filtered gain and creating potential for unfiltered high-channel-count designs. Using a sophisticated computer simulation package, the fiber in a single-stage EDFA can handle 32 simultaneous channels and pump with 100 mW at 980 nm, with a gain flatness of 0.6 dB.
ATOS GmbH, Pfungstadt, Germany
The 10-, 20-, and 40-Gbit/sec high-bandwidth Z-cut Mach-Zehnder lithium niobate intensity modulators with patented ZPol (z-poled) technology produce low driving voltage (VP = 4 V at 10 Gbits/sec), zero or predetermined chirp, and single electrode driving. The single electrode simplifies the driving circuit. Together with the low driving voltage, the single driving also contributes to reduction in power consumption.
