In an optical communication system, the optical signals from the transmitter are attenuated by the optical fiber as they propagate through it. Other optical components, such as multiplexers and couplers, also add loss. After some distance, the cumulative loss of signal strength causes the signal to become too weak to be detected. Before this happens, the signal strength has to be restored. Prio...

This paper attends to demonstrate the usefulness of Design of Experiments (DOE) method in magnetic refrigeration (MR) understanding and optimization. A numerical DOE is applied to a simple 1D finite difference model describing an Active Magnetic Regenerative Refrigeration (AMRR) system. The heat transfer fluid is water, the regenerator consists of stacked gadolinium plates and the model is base...

An efficient optical signal regenerator can mitigate the effect of signal degradation and increase the performance of optical communication system. All optical signal regenerators have been studied and developed for maintaining good quality signal in long haul optical communication. Fiber nonlinearity has some inherent properties for signal regeneration and it has an enormous potential for ultr...

Abstract The manufacturing process and mechanical instability of high performance magnetocaloric materials hamper the implementation novel geometries for active magnetic regenerators. In this work, La(Fe,Si,Mn)13Hy is shaped into a regenerator with triangular microchannels hydraulic diameter 200–300 μm using that results in highly stable structure. characterized regards to heat transfer, resist...
