ABSTRACT: We report a 160 Gb/s OTDM network comprising switching and demultiplexing through field deployed fiber. The 160 Gb/s signal was obtained by time-interleaving 16 channels of a 10 Gb/s signal. The add-drop node was realized by using a gain-transparent operation of a semiconductor optical amplifier (SOA). A subharmonic clock recovery with a pre-scaled electro-optical phase locked loop employing an electroabsorption modulator was applied. An OTDM receiver employed a four-wave mixing principle in an SOA. The impact of fiber chromatic and polarization mode dispersion is discussed. Switching and demultiplexing performance are shown for a fiber link of 275 and 550 km, respectively. Excellent operation of clock recovery, drop-through-add function, and transmission was achieved.

ABSTRACT: This paper reports a 160-Gb/s OTDM network comprising switching and demultiplexing through field deployed fiber. The 160-Gb/s signal was obtained by time-interleaving 16 channels of a 10-Gb/s signal. The add-drop node was realized by using a gain-transparent operation of a semiconductor optical amplifier (SOA). A subharmonic clock recovery with a prescaled electrooptical phase locked loop employing an electroabsorption modulator was applied. An OTDM receiver employed a four-wave mixing principle in an SOA. The impact of fiber chromatic and polarization-mode dispersion (PMD) is discussed. Switching and demultiplexing performance are shown for a fiber link of 275 and 550 km, respectively. Excellent operation of clock recovery, drop-through-add function, and transmission was achieved.

ABSTRACT: The first demonstration of automatic dispersion control suitable for ultra-high-speed 160 Gbit/s transmission over field-deployed fibre is described. Results illustrate the need for adaptive compensation to achieve reliable data transmission at this speed.

ABSTRACT: The authors describe the excellent capability of an all-optical gain-transparent ultrafast nonlinear interferometer (GT-UNI) in dropping, passing through, and adding optical time domain multiplexing (OTDM) channels. Error free operation without significant penalties of a complete OTDM add-drop node at 80 Gbit/s was achieved.

ABSTRACT: Future optical networks will be meshed and transparent. Going towards high-speed optical networks with data rates above 40 Gbit/s per wavelength, optical time domain multiplexing (OTDM) techniques will be applied. Such OTDM networks give rise to a couple of challenges concerning the architecture of add-/drop nodes and optical cross connects. We present a concept for an architecture of an OTDM add-/drop multiplexer and show potential applications. First experimental results proving the feasibility of the OTDM network technology are presented.
