The trial was run over and looped back across Seacom's newly built 930-kilometre Dark Fibre Africa fibre route, which links the Seacom Mtunzini cable landing station on the coast of South Africa's KwaZulu-Natal province to the Teraco data centre in Johannesburg. The trial demonstrates Seacom's commitment to increase the pace at which African networks are deploying cutting-edge telecommunications infrastructure technology to support Africa's rise as a primary scientific and business destination. The trial used Infinera's 500 Gb/s Photonic Integrated Circuits (PICs), each of which integrates five 100 Gb/s coherent channels onto a single chip. The PICs were used for both transmitting and receiving the five 100 Gb/s signals during the trial.
