ADVA has hosted a joint showcase with PSNC at SuperComputing (SC19) in Denver, CO (Nov. 18-21) that features what the companies claim is the industry’s first 1200Gbit/s optical channel transmission.
Built upon the ADVA FSP 3000 TeraFlex terminal, the SC19 demonstration "underscores the power of adaptive technology to maximize bandwidth efficiency in any network scenario," said an ADVA statement, which continued, "Using fractional QAM capabilities to boost fiber utilization and channel capacity, the demo highlights how network operators and enterprises can cost-effectively inject capacity into their networks without major upgrades. At SC19, TeraFlex will carry 1200Gbit/s channels in a 150GHz window or 800Gbit/s channels in a 100GHz window, delivering an industry-leading spectral efficiency of 8bit/s/Hz. These figures set a new benchmark for a commercially available product."
The ADVA FSP 3000 TeraFlex has now been shipping for several months, added the company.
“As we approach the Shannon Limit, our compact and open FSP 3000 TeraFlex provides an entirely new route to network capacity expansion,” commented Christoph Glingener, CTO, ADVA. "This demo reveals how operators can enhance optical paths and reduce cost per bit right now. Transmission terminal design is all about utilizing fiber in the most efficient way, and that’s why our FSP 3000 TeraFlex is the high-speed terminal of choice. By providing a 1200Gbit/s channel that consumes only 150GHz of spectrum, we’re leading the industry with spectral efficiency and channel capacity. Compared with the promise of rival 800Gbit/s solutions that are still many months away, we’re delivering 50% more capacity today – and with the added bonus of significantly better reach.”
As presented at SC19, the live demonstration highlighted how spectral efficiency is key to maximizing bandwidth in existing networks. It showed how super-channels in increments of 50GHz are ideal for maximizing client port flexibility while ensuring compatibility with legacy line systems, added ADVA's statement.
As noted by the company, using software-defined fractional QAM modulation and adaptive baud rate capabilities, the ADVA FSP 3000 TeraFlex can support 1200Gbit/s channels carrying three 400Gbit/s clients or 800Gbit/s channels carrying two 400Gbit/s clients. The reach and spectral efficiency of the dual-core coherent engine implementation is superior to future single-core 800Gbit/s concepts that have reduced client port flexibility and often leave spectrum unutilized.
“Terabit channels are fast becoming essential," concluded Artur Binczewski, director, Network Division, PSNC, who added "Our network enables Europe’s scientific community to share huge data sets and access the most advanced supercomputing applications. But empowering those researchers to stay at the forefront of discovery requires a new level of reach and spectral efficiency. With this demo, we’re showing how mission-critical long-haul networks like ours, which are not fiber-rich, can meet unprecedented data demand. The ADVA FSP 3000 TeraFlex provides the flexibility and granularity needed to squeeze maximum value from our fiber plant. Now we can transmit twelve 100Gbit/s or three 400Gbit/s signals in a single Terabit channel that consumes just 150GHz of spectrum. That level of efficiency enables us to achieve more than we ever thought possible with our DCI network.”
