Role Of Clays Addition On The Stability Of Collapsible Soil Selected From Mosul City

Abstract

In this paper, polarization-insensitive wavelength conversion based on orthogonal-pumps and four-wave mixing in HNLF is experimentally demonstrated for high-speed 112-Gb/s PolMux-RZ-QPSK transmission with digital coherent detection. The conversion performance of the proposed scheme is investigated for both single- and four-channel input signals, with the achieved post-conversion OSNR for the two cases shown to be 30 and 20 dB, respectively.

Finally, the BER of 4{\texttimes}112-Gb/s PolMux-RZQPSK converted signals after 1 km HNLF transmission is measured to be below 1{\texttimes}10-4. The optimum OSNR and launched HNLF power are also investigated.
