Alcatel-Lucent and Apollo achieve 8Tbps capacity

16 July 2015 |


Alcatel-Lucent Submarine Networks (ASN) and Apollo have successfully demonstrated 8Tbps capacity of data per fibre pair on the Apollo South route between France and the US.

8Tbps is equivalent to streaming approximately 1.25 million high definition TV channels simultaneously, and the demonstration saw ASN supply its 1620 Light Manager submarine line terminal, equipped with 100G technology.

“This field trial is another proof point of the adaptability of ASN technology that continues to offer carriers a smart evolution path for tuning capacity and performance throughout the life of a system,” said Philippe Dumont, president of ASN.

“As capacity and connectivity needs continue to increase, the high resiliency to potential degradation at higher speeds combined with the reliability of our technology offer a cost-effective and flexible networking model to cope with content providers and their end-users’ service demands.”

The trial also made use of ASN’s detection techniques and advanced error correction coding, combined with propriety modulation and pulse shaping schemes, in a bid to counteract signal distortions and noise that impact the performance of high-speed, long-distance transmission.

“This new demonstration further proves the technological lead of the Apollo system in offering capacity increased,” said Richard Elliott, managing director at Apollo.

“The achievable capacity of 8Tbps per fibre pair has confirmed once again our expectation; that Apollo could carry around four times the current entire Atlantic traffic in use today.”

This time last year, the two companies hit data transmission speeds of 7.2Tbps during a field trial on the same route.
