“…In addition, control of beamwidth over a frequency band, maximum front-toback (F/B) ratio to avoid interference between neighboring arrays, small size to minimize environmental impact, and low manufacturing costs are some important parameters in the design of these antennas [1].…”

“…Standard EDFAs are still the most attractive solution as the best trade-off between cost and performance in WDM optical transmissions [1] but strong gain fluctuations may arise from traffic flow variations unless an efficient gain control scheme is used. Thus, a low cost and effective control of amplifier power transients is essential for future WDM optical transmissions.…”

A material reflector composed of a metallic ground plane, resistive sheets and, if necessary, elongated rails along the edges of the sheet reflector is presented. The optimized design achieves a front-to-back ratio greater than 30 dB with minimal change in pattern beamwidth. ABSTRACT: Traffic load conditions can excite relaxation oscillations in a chain of gain-clamped erbium-doped fiber amplifiers (EDFA) in packet switched WDM optical networks. Crosstalk interaction dependson the delay between packets and cumulates along the amplifier chain, resulting in great power variations between packets, impairing system performance.
