    Sammanfattning : The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand.

  4. 3. Signal Characterization in Optical Networks

    Författare :Mats Sköld; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The thesis presents and demonstrates methods to characterize high-speed (>10 Gbaud) signals in fiber optic communication systems and networks, including acquisition of the optical signal intensity, amplitude, phase and polarization. These quantities are necessary for the analysis of system performance, both in research and development stages, as well as for monitoring and management of operational systems. LÄS MER

  5. 4. Ultrahigh Capacity Fiber-Optic Transmission Systems

    Författare :Jonas Hansryd; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The subject of this thesis is ultrahigh capacity optical communication systems. Such systems will use a combination of techniques for dense wavelength-division multiplexing (D-WDM) and ultrahigh speed all-optical time-division multiplexing (O-TDM). LÄS MER

  7. 5. Phase-Sensitive Parametric Signal Processing in Optical Communications

    Författare :Abel Lorences Riesgo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis covers the analysis of several schemes for parametric processing in fiberoptic communication systems, focusing mainly on phase-sensitive processing. Vector phase-sensitive amplifiers are characterized and phase regeneration of a dualpolarization (DP)-binary phase-shift keying signal (BPSK) signal is experimentally demonstrated. LÄS MER
