$8 \times 225$ Gbit/S PAM-8 Transmission Employing DFB Laser Array Source and Quantum-DoT SOA-PIN for Intra DCIs

We experimentally demonstrate <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$8 \times 225$</tex> Gbit/s PAM-8 transmission utilizing a 200 GHz -spaced DFB laser array and a quantum-dot SOA-PIN configured receiver. The BER performances of all channels stay under the 20% overhead SD-FEC threshold of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$2 \times 10^{-2}$</tex> after 1 km transmission employing a truncated T-spaced VNLE.
