Huawei Marine Achieves 648.5km Unrepeatered 100G Reach

Huawei Marine Networks Co. announced a record transmission distance of up to 648.5 km for an unrepeatered system in a laboratory test in Beijing.

The laboratory test used Huawei’s 100G technology, enhanced raman amplifier (ERPC), remote optical pump amplifier (ROPA) and ultra-low loss optical fiber. The 100G transmission combined PDM BPSK modulation, ODSP and third-generation soft decision technology.

Huawei Marine's previous record, set in April 2016, was a transmission distance of 627km.

“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.”
