Multi slot amplitude coding technique for high speed optical fiber communication system
… of slots compared to DCDM. The performance of 310 Gbit/s MSAC is -26 dBm for receiver sensitivity (RS) and 25.5 dB for optical signal-to-noise ratio (OSNR). The improvement of 3.5 dB for RS and 3.7 dB for OSNR are obtained when optimize level spacing is implemented. When compared to DCDM, the …

Ultra-long haul optical fibre transmission systems
… have allowed regenerators operating at 10 Gbit/s to become a practical reality. By augmenting such devices with optical amplifiers it is possible to greatly enhance the repeater spacing. Work detailed in this thesis has culminated in the propagation of 10 Gbit/s data over 400,000 km with …

High-Speed Modulation of Semiconductor Lasers and Modulators
… used in the real system at bit rates below 10 Gbit/s and has drawbacks such as chirping and low bandwidth. To improve the high-speed performance of a single laser, we intensively study the injection locking technique. It is shown that this technique greatly reduces chirping, improves …

Performance of multichannel fiber optic parametric amplifier
… optical amplifier is perform by simulation of 10 Gbit/s each channel. Furthermore NRZ encoding technique, intensity OOK modulation format has been used in this simulation. The frequencies of channel carrier was chooses in the region from 193.1 THz to 193.8 THz. Eight modulated signal are …

The Impact of Higher Order Pulse Amplitude Modulation and Transmission Performance over Twisted Pair Cable
… time of writing this thesis, data rates of up to 10 GBit/s over a transmission distance of 100 m and 40 GBit/s over a transmission distance of 30 m are standardized for symmetrical copper cabling [2]. Other lengths are not standardized. Short lengths in particular are of great interest for copper …

Holey optical fibres for high nonlinearity devices
… error free-penalty free wavelength conversion of 10 Gbit/s data signals over a 10 nm bandwidth. As shown by these experiments one major issue of our HFs is the high polarization mode dispersion. We suggest a possible route to the solution of this problem, by systematically investigating the …

Transmission capacity improvement for high speed multimode waveguide links using advanced optical launch and multilevel modulation schemes
… range of ≤ 8 μm. Error free transmissions at 10 Gbit/s are demonstrated for different orders of low-loss Hermite-Gaussian launches over 250 m worst case OM1 fibre without the use of equalisation. The second half of the dissertation concentrates on another type of multimode waveguide which is …
