News Summary:

Telstra transmitted four 400GbE client services over a single 1.6 Tbps wavelength across approximately 1100 km between Melbourne and Sydney on September 8, utilizing Ciena WaveLogic 6 Extreme (WL6e) coherent technology on its live production network. The wavelength operated in L-band spectrum without regeneration, extending the distance of Telstra and Ciena’s previous 1.6 Tbps demonstration by approximately 50%. Earlier on September 8, the Australian Communications and Media Authority (ACMA) penalized Telstra $277,200 after finding the telco failed to act on warnings that 13 customers were at risk of fraud, resulting in losses exceeding $39,500. These customers fell victim to unauthorized SIM swaps between January and October last year, with ACMA's investigation concluding that Telstra staff repeatedly neglected to follow basic identity checks designed to prevent criminals from taking over mobile numbers. This penalty marks the seventh enforcement action in a broader regulatory crackdown on Australian telcos regarding SIM swap failures.
