[HSSG] (Nearly) All you wanted to know about high speed transmission ... but were afraid to ask

As a newbie to the considerations of high speed optical data transmission I found the following to be of use and a reasonable grounding in the subject.

These are all taken from the Journal of Lightwave Technology, Vol. 24, Issue 12 (Dec2006).

Are there any other recommended readings?

Future Optical Networks
Michael J. O'Mahony, Christina Politi, Dimitrios Klonidis, Reza Nejabati, and Dimitra Simeonidou 
Journal of Lightwave Technology, Vol. 24, Issue 12, pp. 4684-4696 

This paper presents views on the future of optical networking. A historical look at the emergence of optical networking is first taken, followed by a discussion on the drivers pushing for a new and pervasive network, which is based on photonics and can satisfy the needs of a broadening base of residential, business, and scientific users. Regional plans and targets for optical networking are reviewed to understand which current approaches are judged important. Today, two thrusts are driving separate optical network infrastructure models, namely 1) the need by nations to provide a ubiquitous network infrastructure to support all the future services and telecommunication needs of residential and business users and 2) increasing demands by the scientific community for networks to support their requirements with respect to large-scale data transport and processing. This paper discusses these network models together with the key enabling technologies currently being considered for!
  future implementation, including optical circuit, burst and packet switching, and optical code-division multiplexing. Critical subsystem functionalities are also reviewed. The discussion considers how these separate models might eventually merge to form a global optical network infrastructure. 

Recent Advances in Ultrahigh Bit Rate ETDM Transmission Systems
Eugen Lach and Karsten Schuh 
Journal of Lightwave Technology, Vol. 24, Issue 12, pp. 4455-4467 

Increase of Internet traffic and introduction of triple-play services force operators to increase network capacity at moderate costs. Introduction of higher electronic time-division multiplexing (ETDM) channel bit rate targets reduce the cost per bit for the transmission due to lower power consumption, smaller footprint, less management effort, and complexity of the systems. Improved performance of electronic and optoelectronic components allows for research on ETDM bit rates beyond 40 Gb/s, which is currently the highest standardized channel bit rate for optical telecommunication networks. In this paper, an overview of recent progress in high-speed ETDM technology for 80 Gb/s and beyond and results of high-speed ETDM transmission experiments are given. Currently, the speed of electronics enables ETDM systems with line rates of 80/85 Gb/s and even 100 Gb/s, which is expected to be the next generation of Ethernet in data communication. 

Ultrahigh-Speed OTDM-Transmission Technology
Hans-Georg Weber, Reinhold Ludwig, Sebastian Ferber, Carsten Schmidt-Langhorst, Marcel Kroh, Vincent Marembert, Christof Boerner, and Colja Schubert 
Journal of Lightwave Technology, Vol. 24, Issue 12, pp. 4616-4627 

This paper reviews ultrahigh-speed data transmission in optical fibers based on optical time division multiplexing (OTDM) transmission technology. Optical signal processing in the transmitter and receiver as well as the requirements on ultrahigh-speed data transmission over a fiber link are discussed. Finally, results of several OTDM-transmission experiments, including 160-Gb/s transmission over 4320 km, 1.28-Tb/s transmission over 240 km, and 2.56-Tb/s transmission over 160-km fiber link, are described. 

Advanced Modulation Formats for High-Capacity Optical Transport Networks
Peter J. Winzer and Renč-Jean Essiambre 
Journal of Lightwave Technology, Vol. 24, Issue 12, pp. 4711-4728 

Advanced optical modulation formats have become a key ingredient to the design of modern wavelength-division-multiplexed (WDM) optically routed networks. In this paper, we review the generation and detection of multigigabit/second intensity- and phase-modulated formats and highlight their resilience to key impairments found in optical networking, such as optical amplifier noise, chromatic dispersion, polarization-mode dispersion, WDM crosstalk, concatenated optical filtering, and fiber nonlinearity.
