Pipe International has completed the final splice on its PPC-1 subsea cable between Sydney and Guam, transmitting the first light across the system.
According to a blog post, work was completed early Saturday morning followed by "various optical and powering tests and assessments".
"[It] means that for the first time, Sydney, Guam and Madang [Papua New Guinea] are connected by a continuous piece of fibre-optic glass," the company said.
The splice marked the completion of the marine program of work.
The cable was expected to launch to commercial traffic on October 8th.
