An Overview of Broad-Band Access Technologies
The provision of broad-band services based on either the Internet or the asynchronous transfer mode (ATM) technique requires a new generation of access networks. In the short term, solutions such as x-digital subscriber line (DSL) and hybrid fiber coaxial (HFC), allowing the reuse of existing infrastructures, look very promising. For the longer term, new infrastructures based either on radio or...
متن کاملCharacterizing an Improved Broad Band Impedance*
A phenomenological model of broadband impedance containing two free parameters has been recently proposed. This paper attempts to assign physical charaterizations to these free parameters by relating them to the geometric dimensions of a stand-alone cavity structure. Contributed paper at the Broadband Impedance Measurements and ModelZing Workshop SLAC, Stanford, USA February 28 March 2, 2000 ‘W...

support these gains where possible. A drawback of the VIS is the difficulty of coding. Although the function-call syntax means the programmer does not have to manipulate registers directly, the need to manipulate multiple data words in parallel takes some effort on the programmer's part. We venture to suggest that VIS coding is as hard as, if not harder than, typical DSP coding. We were, howeve...
متن کاملBroad-Band Difference Interferometer
Thanks to researches and the development of integrated optics devices for optical applications in the telecommunications, relatively cheap sources and detectors of optical radiation that can be used in the design of planar optical sensors [1, 2]. One of the commonly used sensor systems is the differential interferometer, based on planar waveguides [3]. In the analyzed system propagates a mode f...
متن کاملBroad-Band Activatable White-Opsin
Currently, the use of optogenetic sensitization of retinal cells combined with activation/inhibition has the potential to be an alternative to retinal implants that would require electrodes inside every single neuron for high visual resolution. However, clinical translation of optogenetic activation for restoration of vision suffers from the drawback that the narrow spectral sensitivity of an o...
