FSP 3000 TeraFlex™ Submarine Demo Transports Data 6,800km Using Commercial Transponder
ADVA reports that its FSP 3000 CloudConnect™ TeraFlex™ system has succeeded in transporting 300 Gbits/s of data per wavelength over a 6,800 km fibre link. Conducted alongside ADVA’s partner Acacia Communications Inc, the trial is billed as “…the first in the industry to cover the trans-Atlantic distance with a fibre link typical of a cost-optimised submarine cable using 300 Gbits/s channels and a commercially available transponder with real-time Digital Signal Processing (DSP)”. The demo, which also is claimed to have achieved the highest spectral efficiency for such a link carrying 300 Gbits/s per wavelength with 70 GHz channel spacing, was designed to highlight the capabilities of the ADVA FSP 3000 TeraFlex™ solution to support flexible, ultra-high-capacity, long-haul and subsea data transport.
“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,” stated Sorin Tibuleac, Director, System Architecture, R&D, ADVA. “We’ve already shown that our FSP 3000 TeraFlex™ supports the growing bandwidth needs of metro DCI infrastructure with successful 600 Gbits/s trials. Now we’re proving what it can do over the world’s longest links. 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-datacentre connections to inter-continental links. To accomplish that over a fibre cable with trans-Atlantic reach is a truly unique achievement.”
The trial network featured ADVA’s solution that delivers 36 bidirectional 100 Gbits/s Ethernet services in a 1RU chassis, and can transport up to 600 Gbits/s on a single wavelength. It also delivers real-time telemetry streaming – a prerequisite for big databased network management.
“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, DSP and Optics, Acacia Communications. “With the ADVA FSP 3000 TeraFlex™ platform, which incorporates the suite of advanced performance features in our Pico coherent DSP, we’re helping to enable network operators to upgrade existing infrastructure to support higher density at lower power.”
