In this paper we review two different field trials performed by Alcatel-Lucent in collaboration with two of the largest carriers in Europe: Telefonica and Telecom Italia.
We present the unrepeatered transmission of a dual carrier 400 Gb/s PDM-16QAM channel over 401 km, mixed with 100 Gb/s PDM-QPSK channels.
We transmit a 406.6-Gb/s superchannel consisting of eight 37.5-GHz-spaced 32-Gbaud Nyquist-filtered PDM-BPSK signals over 12,800-km (160x80-km) EDFA-only amplified dispersion-unmanaged TWRS fiber.
We compare conventional and coherent solutions for 40 G and 100 G operations.
Transmission at 40G over a 10G infrastructure needs compatible dispersion management.
The intended objective of this article is to provide designers with the basic knowledge to implement an Ethernet long-reach 40 Gb/s and 100 Gb/s host board.
Different aspects of electronic distortion equalization at 40Gbit/s are highlighted: from the experimental assessment of analog equalizer circuits to the estimation of the digital processing effort
We report here a new progress of Remote Amplified Modulators for wavelength flexible and transceiver cost sensitive fix/mobile access, metro and short reach networks.
We demonstrated 40Gbit/s optical link by coupling a silicon (Si) optical modulator to a germanium (Ge) photodetector from two separate photonic chips.
A polarisation-independents, push-pull InP Mach-Zehnder modulator for 40Gbit/s all-optical regeneration has been implemented in a loop transmission scheme.
