Verizon and Infinera Set World Record for Real-Time Polarization Mode Dispersion Compensation

The evaluation of polarization mode dispersion (PMD) performance is necessary in the fiber characterization process, because it enables service providers to upgrade and maintain their networks to deliver optimum quality service to their customers.

Infinera and Verizon (News - Alert) have collectively published a report on real-time PMD performance, detailing the results of a record-breaking achievement for real-time polarization mode dispersion (PMD) performance, with Infinera's (News - Alert) coherent optical transmission based on 500 Gigabit per second (Gb/s) photonic integrated circuits (PIC).

Infinera is a provider of digital optical communication system designs to improve the economics of optical networking by combining the speed of optics with the simplicity of digital.

Benefits of the advanced signal processing built into the modem are taken into consideration to provide an accurate measurement of PMD. The report presents the performance for both first-order and second-order PMD.

The near-perfect precision model has been used to track high amounts of PMD and fast polarization transients.

"Our team, with Verizon, was able to demonstrate a coherent optical transmission that can handle large PMD values with our commercially available 500 Gb/s PIC," said Dave Welch, Infinera cofounder, EVP and chief strategy officer at Infinera. "System vendors in the industry today are having a difficult time achieving this. Not all coherent systems are the same. This paper illustrates the robustness of our optical solution and is a tribute to our brilliant teams here in Sunnyvale and in our Ottawa Design Center, developing the algorithms to make this possible."

Infinera's system runs on PIC technology. The company offers its customers a service-ready architecture that enables fast time-to-revenue and generates sales and profitability through network efficiency, and the ability to rapidly deliver differentiated services without reengineering their optical infrastructure.

 In other company news, TMCnet reported that Infinera's submarine solution to help Kodiak Kenai Cable upgrade its optical Subsea network.
