We present an improved approach for SBS based in-band OSNR monitoring with a drastic enhancement of the dynamic monitoring range for 44.6 Gbps DPSK and 112 Gbps DP-QPSK signals by intentionally adding...
We consider traffic grooming and regenerator placement in an optical network in which lightpaths are hop-constrained by impairments. Combining grooming with regenerator placement reduces costs compare...
A method for extending the customer density via ASE-pumped splitters in the tree in a WDM/TDM-PON is presented. The influence of Rayleigh backscattering in the feeder is faced,originally prohibiting a...
The issues and challenges associated with network planning and engineering of a dynamically reconfigurable all-optical network will be discussed. Possible solutions will be outlined and the effectiven...
