Serial 107Gbit/s ETDM NRZ Transmission over 320km SSMF

Abstract

We report on a complete serial 107 Gbit/s ETDM NRZ transmission system and assess system performance in an error free transmission experiment over 320 km SSMF with 3.5 dB OSNR margin.

“…We then describe the generation of a single channel 100 Gb/s signal. Several groups have proposed and demonstrated 100 Gb/s transmitters, such as using NRZ (Schuh et al, 2007), duo-binary (Winzer et al, 2005), and differential quadrature phase shift keying (DQPSK) (Daikoku et al, 2006) and serial dark-return-to-zero (SDRZ) (Ellis & Chow, 2006).

8 Tb/s (80 × 107 Gb/s) DWDM NRZ-VSB transmission over 510 km NZDSF with 1 bit/s/Hz spectral efficiency

“…The PLC-based optical equalizer applied in our setup was originally designed as a tunable dispersion compensator for 40 Gb/s applications [7] and consists of seven cascaded Mach-Zehnder interferometers. In contrast to [4], we use the optical equalizer in front of our 107 Gb/s ETDM receiver to improve signal quality there [15]. The equalizer characteristic is tunable by electrical heaters.…”

“…Compared to the input signal the optical modulation bandwidth is increased at the equalizer output [15], as seen in Figure 2.…”

“…With the classical 107 Gb/s amplitude shift keying non-return-to-zero (ASK-NRZ) approach, DWDM transmission was demonstrated with a minimum channel spacing of 143 GHz [22] and also 200 GHz [14]. Here, we propose and demonstrate the application of optical vestigial sideband (VSB) filtering to binary 107 Gb/s ASK-NRZ signals enabling a DWDM transmission on a 100 GHz channel grid, i.e., a comparable spectral efficiency (1 bit/s/Hz) to that achieved by the 50 Gbaud DQPSK modulation format [21].…”

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

“…Ten channels were transmitted over 400 km with a spectral efficiency (SE) of 0.7 b/s/Hz (143 GHz channel spacing). Currently, the availability of mature high-speed electronics and optoelectronics is limited and thus most binary 100 Gb/s demonstrations have occurred in research labs [8,32,36,37,39,50]. In an effort to improve the spectral efficiency and reach, more advanced modulation formats are being explored [12,47].…”
