10.2 Tbit/s (256x42.7 Gbit/s PDM/WDM) transmission over 100 km TeraLight/sup TM/ fiber with 1.28 bit/s/Hz spectral efficiency

We demonstrate the transmission of 256 polarization-division and wavelength-division multiplexed channels at 42.7 Gbit/s rate over 100 km of TeraLight/sup TM/ fiber. An overall capacity of 10 Tbit/s is achieved in C and L bands at a record 1.28 bit/s/Hz spectral efficiency.

Impact of pump phase modulation on the gain of fiber optical parametric amplifier

In practice, fiber optical parametric amplifiers are generally driven by a phase-modulated pump wave to avoid stimulated Brillouin back-scattering. We show both analytically and numerically that the phase modulation of the pump can induce strong parametric gain modulation and that this detrimental effect depends both on the rise-fall time of the phase modulator and on the fiber dispersion slope.

Impact of pump OSNR on noise figure for fiber-optical parametric amplifiers

Electrical measurements of the noise figure of a fiber-optical parametric amplifier are presented and compared with optical measurements. The transfer of pump noise by four-wave mixing was clearly demonstrated. A numerical model was developed to simulate the transfer of pump noise and validated by these measurements. Using this model, we determine, for practical systems, a minimum required pump optical signal-to-noise ratio of 65 dB.

Cost-optimized 6.3 Tbit/s-capacity terrestrial link over 17 /spl times/ 100 km using phase-shaped binary transmission in a conventional all-EDFA SMF-based system

We demonstrate the feasibility of 6.3 Tbit/s capacity over 17 /spl times/ 100 km using well-proven all-erbium-doped fiber amplifier technology over a typical ultra-long haul link based on standard fiber. This experiment emphasizes the advantages of our modulation format, namely phase-shaped binary transmission.

Zero-dispersion wavelength mapping in short single-mode optical fibers using parametric amplification

We demonstrate a novel convenient nondestructive method based on optical parametric amplification that allows retrieval of the zero-dispersion wavelength map along a short optical fiber span with a high-spatial resolution. The improved resolution relies on the high sensitivity to the local longitudinal dispersion fluctuations of the parametric high-gain spectrum.

Transmission of 125 WDM channels at 42.7 Gbit/s (5 Tbit/s capacity) over 12/spl times/100 km of TeraLight/spl trade/ Ultra fibre

The transmission of 125 ETDM channels at 42.7Gbit/s (5 Tbit/s capacity) is demonstrated over 12/spl times/100 km of the new TeraLight/spl trade/ Ultra fibre. The result is obtained with VSB-like filtering at the receiver end and Raman-assisted erbium amplification over C and L bands.

3.2 Tb/s (80 /spl times/ 40 Gb/s) C-band transmission over 3 /spl times/ 100 km with 0.8 bit/s/Hz efficiency

We demonstrate 50 GHz-spaced 80 /spl times/ 40 Gbit/s WDM transmission over 300 km of TeraLight/spl trade/ fibre without polarisation demultiplexing, using the PSBT format. A record capacity of 3.2 Tbit/s is thus achieved over the C-band only, with a spectral efficiency of 0.8 bit/s/Hz.

Nanoparticle Doping Process: towards a better control of erbium incorporation in MCVD fibers for optical amplifiers

Germano-silica and alumino-silica Erbium Doped Fibers have been fabricated through a new Nanoparticles Doping process with MCVD technology. These fibers have been characterized in WDM amplification experiments in both C and L band.

Impact of the longitudinal variations of the chromatic dispersion on the gain of fiber parametric amplifiers

We study experimentally the detrimental impact of longitudinal variations of chromatic dispersion on the gain of a broadband fiber optical parametric amplifier. Thanks to the optimization of the pump wavelength, a 3dB-gain bandwidth of 25nm is demonstrated using only 740mW pump power.

Cascadability of Optical Packet-Switching Nodes Based on (R)SOA Devices

We evaluate the benefits and limitations of semi-conductor optical amplifiers (SOAs) and reflective SOAs, when used as logic gates in a 10 Gbit/s per wavelength WDM packet-switched network. We compare three components with different internal structures and provide estimation of the maximum number of cascaded packet-blocker-based nodes.
