Field trial of 107-Gb/s channel carrying live video traffic over 504 km in-service DWDM route

Abstract

A 107-Gbps field trial carrying live HDTV traffic over a 504-km in-service DWDM route, proving commercial systems designed for 10G/40G can be upgraded to 100G without impacting existing active channels.

Optical channel capacity: 100 Gb/s, Tb/s and beyond

“…The world's first 100G field trial with live traffic was accomplished in 2007 [15][16][17]. The configuration of the trial is shown in Figure 2.…”

100 Gb/s DQPSK field trial: Live video transmission over an operating LambdaXtreme® network

“…Finally, we detail the field programmable gate array (FPGA)-based real-time encoding and decoding that is required to carry the live video signals using DQPSK. We demonstrate successful implementation through the transmission of high-definition television channels over the system carrying live traffic [46,51].…”

“…Through the above process, we mimic an equivalent 10 ϫ 10. Ethernet (GbE) stream and tapped optically to provide an OC-192 (9.95 Gb/s) signal to the input of the 107 Gb/s transmitter in Tampa [46]. The OC-192 signal is fed to the client port for G.709-compliant enhanced FEC encoding to produce an OTU-2 framed signal at 10.7 Gb/s, as shown in Figure 15.…”

Optical channel speeds for future transport networks

“…OIF has chosen the ETDM design polarization multiplexed quadrature phase shift keying (PM-QPSK) as the modulation format for 100-Gb/s channels of optical transport systems (for line side of the equipment), with a symbol rate between 28 and 32 Gbaud [11]. The first 100G field trial with live traffic was accomplished in 2007 [12][13][14]. The configuration of the trial is shown in Figure 1.…”
