OSNR degradation at an optical performance monitoring site within a network is correlated with end terminal performance for fault localization.
We describe a simple method to measure the optical signal-to-noise ratio (OSNR) of on-off-keying (OOK) and differential phase-shift-keying (DPSK) signals by using an optical delay interferometer (O
We describe a simple method to measure the optical signal-to-noise ratio (OSNR) of OOK and DPSK signals by using an optical filter with a periodic and tunable passband.
We demonstrate machine learning augmented Open Shortest Path First (OSPF) routing which infers Shared Risk Groups (SRG) from link failure history.
Cloud computing is currently based on hardware virtualization wherein a host operating system provides a virtual machine interface nearly identical to that of physical hardware to guest operating s
The rapid emergence of voice over Internet Protocol (VoIP) networks and their enticing appeal to a broad base of customers are driven by economic incentives, improved productivity, and creation of
The rapid emergence of voice over Internet Protocol (VoIP) networks and their enticing appeal to a broad base of customers are driven by economic incentives, improved productivity, and creation of
We report system simulation and experimental results on enhanced transmission distance over standard single mode fiber thanks to a novel dual modulation technique that generates a wideband optical
False color environmental scanning electron microscope (ESEM) images of subcooled water droplet freezing on a superhydrophobic copper oxide (CuO) surface are presented (a).
Three dimensional clustering has been observed in thin film depositions of Sn, Ga, and Ge on Si.
