100-Gb/s DQPSK Field Trial: Live video transmission over an operating LambdaXtreme® network

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 the existing network bearing live traffic to 100 Gb/s per wavelength without any changes to the current hardware or software. The 100-Gb/s signal is added at a reconfigurable add/drop multiplexer (ROADM) at a network node in Tampa and dropped at a ROADM in Miami where both live video and pseudorandom test sequences are observed. In addition, we discuss the steps leading up to this field trial that included several important laboratory experiments. We detail the generation, detection, coding and long-haul transmission of single-polarization DQPSK at a line rate of 53.5 Gbaud to support a net information bit rate of 100 Gb/s.
