Error-free transmission over 50 km single mode fiber of 8 WDM ITU channels with 100 GHz channel spacing is demonstrated at 10 Gbit/s by using comb generation in a quantum dash mode-locked laser.
What is the sensitivity of a direct-detection lightwave receiver employing an optical preamp? Published calculations for on- off keyed signals differ by a factor of four.
Consider many P C M messages occupying adjacent frequency bands in the same transmission medium, as, for example, in the proposed long distance waveguide communication system.1 At some point the me
The ES/AG (Expert System/Application Generator) Environment consists of a set of languages and tools for creating expert systems from a task specific knowledge base.
In the frame of an ESA contract, Alcatel ETCA has developed and qualified a new generation medium power EPC (Electronic Power Conditioner) for space TWTA's (Travelling Wave Tube Amplifier).
In this paper we present ESC: an efficient, scalable, and crypto-less solution for the establishment of a secure wireless network (that is, a network where, for any couple of nodes, there exists a
We have measured the escape rate of electrons from 2-D surface states on bulk Helium.
Common ESD protection devices have a snap-back characteristic similar to a silicon-control-rectifier.
Lucent Worldwide Services (LWS) is the services arm of Lucent Technologies.
