Multi-element fiber for space-division multiplexed optical communication system [PDF]
, 2014 This paper reviews a novel approach of implementing space-division multiplexing (SDM) based on Multi-element Fiber (MEF) technology. The MEF geometry provides for ultra-low crosstalk between the spatial channels while full compatibility with standard WDM

Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]
, 2000 We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...
