ADVA Optical Networking has announced that it has transported 300Gbit/s of data per wavelength over a 6,800km fibre link.

Using its FSP 3000 CloudConnect TeraFlex technology trials were conducted with ADVA’s partner Acacia Communications and was the first trial to cover the trans-Atlantic distance with a fibre link typical of a cost-optimised submarine cable using 300Gbit/s channels and a commercially available transponder with real-time digital signal processing (DSP).

“This lab trial proves the power of our FSP 3000 TeraFlex to deliver scalable long-haul data transmission with the highest spectral density at the lowest cost-per-bit. It shows subsea and intercontinental network operators that our solution is an ideal choice for transporting enormous amounts of data with the utmost flexibility in symbol rate, modulation format, and channel spacing to maximise the capacity of any given network,” said Sorin Tibuleac, director, system architecture, R&D, ADVA.

The demonstration also achieved the highest spectral efficiency for such a link carrying 300Gbit/s per wavelength with 70GHz channel spacing.

“What makes this trial so significant is that it leverages a commercially available solution that can be configured to achieve the highest capacity on any distance from inter-data centre connections to inter-continental links. To accomplish that over a fibre cable with trans-Atlantic reach is a truly unique achievement, ” continued Tibuleac.

The FSP 3000 TeraFlex solution delivers 36 bidirectional 100Gbit/s Ethernet services in a 1RU chassis and can transport up to 600Gbit/s on a single wavelength. It also maximises the transmission capacity for any given fibre link, from access networks to links spanning submarine distances. In addion, as part of the ADVA FSP 3000 CloudConnec platform, it’s completely open and programmable delivering real-time telemetry streaming.

“Triggered by increasing demand for data driven by cloud-based services, we’re seeing a significant expansion in long-haul and subsea cable networks. This trial broadens the horizons of what can be achieved over great distance in terms of capacity and modulation flexibility,” added Christian Rasmussen, founder and VP, digital signal processing and optics, Acacia Communications. 

“We believe this trial gives a major boost not only to long-haul and submarine network operators but also to cloud-content and digital media providers looking for ways to cost-efficiently deliver more to their customers around the globe.”
