Fibre capacity demand across global networks is driving the need for continued innovation in coherent optical system design. Network requirements are also diverging, creating different feature sets for both mechanical form and performance depending on the application. These trends are converging with new wafer-scale processing for key foundational technologies that other benefits of circuit integration, performance and manufacturability. Two technologies underpin the electro-optical transmit and receive chains for today’s coherent systems: indium phosphide (InP) and silicon photonics (SiPhot). Patricia Bower, Senior Manager, Portfolio Marketing at Ciena explains.

The Network System Research Institute at Tokyo’s National Institute of Information and Communications Technology, Japan, has demonstrated the first large-scale optical switching testbed capable of handling 1 petabit/s optical signals.” 1 petabit/s is equivalent to the capacity to send 8K-quality video to 10 million viewers simultaneously. The NICT stated that this achievement depended on large-scale […]Read More
