Paper Abstract

This paper describes installing the first two portions of a fiber-optic based image-transmission network. The network topology is a star. The system is controlled by logical circuit switching of broadcast signals. High-speed operation is attained by two means: First, the signalling speed of the network is 144 Megabits/second. Second, wavelength multiplexing is used to separate the control signals and image-transmission signals. This paper describes the installation and integration of two arms of the network star. The arms include: the star coupler (SC), two network interface units (NIU), two interface translation units (NIU), and two units of imaging equipment (IE). Development of the system components was done separately at the Department of Radiology, University of Arizona (UofA) in the U.S.A. and at the Toshiba Medical Imaging Laboratories in Japan. The SC and NIU's were constructed by Toshiba while the ITU's and IE's were constructed by the UofA. The system integration was done at the University of Arizona by a team with members from both locations.
