Huawei Marine said it has further increased the transmission distance of unrepeatered submarine cable systems in a laboratory test in Beijing.
In April 2016, Huawei Marine achieved a transmission distance of 627 kilometers, based on its 100G technology, enhanced raman amplifier (ERPC) and remote optical pump amplifier (ROPA).
However, the company said it has now increased this transmission distance at up to 648.5 kilometers.
The laboratory test was performed on a 100G/s channel over an ultra low loss optical fiber by using Huawei Marine’s self-developed ERPC and ROPA.
“Huawei Marine has achieved another breakthrough in unrepeatered system design which demonstrates our continuous commitment to investing in high-performance technology,” said Zhang Shigui , vice president of Technology, Huawei Marine. “When used commercially, this technology will broaden the range of unrepeatered system applications and create value for our customers.”
