We demonstrated a 400Gb/s Ethernet end-to-end circuit, inclusive of 400GbE client card with CPF8 interface and dual-carrier 16QAM line-side, on a production 100G core network segment between New York City and Washington DC. During the field trial, we demonstrated the feasibility of SDN-enabled creation, deletion, and re-routing of the 400G service.

Successful transmission of live (real time) video traffic is demonstrated using a prototype 100 Gb-s single-polarization differential quadrature phase shift keying (DQPSK) transmitter and receiver over an in-service 504 km link of the LambdaXtreme® optical transport platform. Teaming with Verizon Business, we demonstrate the feasibility of upgrading an existing, live traffic bearing network to 100 Gb-s per wavelength without any changes to the current hardware or software. The 107 Gb-s signal is added at a reconfigurable optical add-drop multiplexer (ROADM) at a network node in Tampa, Florida, and dropped at a ROADM in Miami, Florida, where both live video and pseudorandom test sequences are received. In addition, we discuss the steps leading up to this field trial that included several important precursor laboratory experiments. We detail the generation, detection, coding, and long-haul transmission of single-polarization DQPSK at a line rate of 53.5Gbaud to support a net information bit rate of 100 Gb-s. © 2010 Alcatel-Lucent.

We demonstrate 107-Gb/s single-channel transmission over the commercial all-Raman LambdaXtreme® transport system. Both RZ-DQPSK and NRZ-DQPSK formats were transmitted over 700 km with one reconfigurable optical add drop multiplexer (ROADM) node at 500 km.

The LambdaXtreme® Transport System was designed to enable all-optical transmission for unprecedented distances, without regeneration and with ultra-high capacity. In this paper, we provide a detailed view into what was done before, during, and after a nationwide deployment to ensure that the network builds would be completed on time and perform as designed.
