**************************************************************************** The Microwave Image Transimpedance Front-End Amplifier For Optical Receivers **************************************************************************** The image impedance network used in distributed amplifiers is employed in the design of a transimpedance optical receiver front-end at microwave frequencies. Compared with the conventional design, for the same transimpedance the current design has more than twice the bandwidth, or for the same bandwidth it has 3 dB better sensitivity. A front-end is designed for 10 Gb/s transmission with a sensitivity of -2...

OVERVIEW OF BELLCORE METROCORE\*(Tm NETWORK A. Albanese, M. W. Garrett, A. Ippoliti, M. A. Karr, M. Maszczak, and D. Shia Bell Communications Research Morristown, New Jersey 07960, USA (201) 829-4291 The Bellcore METROCORE\*(Tm network is a test bed prototype of a metropolitan area network (MAN) for exploring new network concepts and technology applications in broadband communications. The present design and status of the METROCORE network research prototype are outlined. This system operates at 150 Mb/s with the potential for upgrading to 2.4 Gb/s. A basic hardware architecture has been designed which consists of a network inter...

Mismatch detection useless in finding data mutilation caused by program bugs. Data maintenance aided by ease of communication among prog...
