Communication Network with Skew Path Monitoring and Adjustment

Abstract: Embodiments of the present invention route a WDM signal across multiple communication paths using skew characteristics of at least some of the communication paths. The network is an optical transport network, using either circuit or packet based switching, and wavelength division multiplexed wavelengths and/or optical carrier groups (“OCGs”) over a fiber link to another node in the network. The plurality of communication paths involves different signal and path attributes such as a plurality of carrier wavelengths, optical carrier groups, physical communication paths (different nodes, different fibers along a same path, or any combination of the foregoing), or any other differentiating factors between two paths.

Method and arrangment for stabilizing wavelength of multi-channel optical transmission systems

Abstract: The invention relates to a method and a device for wavelength stabilizing for multichannel optical transmission systems An optical multiplexer is used directly for the generation of the optical total signal This makes possible a simple electronic regulation of wavelengths of the optical carrier signals through analysis of the amplitude values of low-frequency signals, which modulate the optical carrier signals by means of amplitude modulation

Ring gain control in WDM optical signal transmission system

Abstract: A signal transmission system has a number of wave division multiplex optical carriers linking a number of switching units arranged in a closed ring network. The carriers are amplified to compensate for loss and attenuation, but the ring gain of each carrier must be less than unity to prevent unwanted signal oscillation. An automatic gain control arrangement is operative for each optical carrier which is detected as being present at a switching unit, and the gain control is disabled for each carrier which is detected as being absent.

Analysis of the carrier-suppressed single-sideband modulators used to mitigate Rayleigh backscattering in carrier-distributed PON.

Abstract: By using the carrier-suppressed single-sideband (CS-SSB) modulation, the Rayleigh backscattering (RB) experienced by the uplink signal can be effectively mitigated due to the reduction of the spectral overlap between the uplink signal and the distributed optical carrier. In this work, we first introduce the theoretical analysis of the CS-SSB generation using the dual-drive MZM (DD-MZM)-based and a dual-parallel MZM (DP-MZM)-based optical networking units (ONUs). Due to the different modulation mechanisms of the two CS-SSB modulations, the frequency components of the generated CS-SSB signals are also different. The transmission performance and the dispersion tolerance of the uplink signals generated by the two CS-SSB modulators are also analyzed and discussed.

Simultaneous transmission of 100 Mbit/s at baseband and 60 FM video channels for a wideband optical communication network

Abstract: A wideband optical communication system is demonstrated over 12 km of optical fibre which simultaneously transmits both a 100 Mbit/s baseband digital signal and 60 FM video channels subcarrier multiplexed in the 2.7–5.2 GHz band.
