Characterization of the polarization mode dispersion of single mode fibre in KAT-7 telescope array network, South Africa

Abstract

We experimentally investigate the differential group delay (DGD) in KAT-7 optical fibre network using polametric measurement technique. Low PMD values in the femtosecond range are obtained over the 10 km single mode fibre. It is also established that deployment of the fibre alters the DGD of the network. This study is paramount in ensuring accurate and stable clock signal as well as error free transmission at very high bit rates in the optical network.
