TE Subcom transmits 200 Gbps, 400 Gbps undersea
A day after Alcatel-Lucent announced a high-speed multi-rate optical transmission demonstration over terrestrial fiber, TE SubCom, a TE Connectivity Ltd. company, says it has done the same thing over an undersea fiber-optic network. The company says it successfully transmitted 200-Gbps and 400-Gbps signals over a single fiber pair.
The company reported the achievement in a post-deadline paper at OFC/NFOEC last month. In the presentation, TE Subcom said it demonstrated a total capacity of 21 Tbps over more than
First, TE Subcom engineers transmitted 106 channels at 200-Gbps each over
“Transpacific length transmission at 6-bps/Hz spectral efficiency is a significant milestone for undersea communications,” said Seymour Shapiro, CTO, TE SubCom. “More impressive is that this was achieved using both 200-Gbps and 400-Gbps channels and large total capacity. Such 400-Gbps laboratory experiments typically require multiple coherent receivers, whereas our recent demonstration used a single high-bandwidth receiver.”
