Our joint showcase with PSNC at SC19 features the industry’s first 1200Gbit/s optical channel transmission. 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. Find out more about the power of adaptive technology to maximize bandwidth efficiency in any network scenario.
