DEC Computers
A star coupler was also the name of a device sold by Digital Equipment Corporation (now part of Hewlett-Packard) of Maynard, Massachusetts. In this case, the star coupler interconnected links to computers via coaxial cable rather than optical fibres, but the function was essentially the same. The signal that was distributed was 70 Mb/s computer interconnect (CI) data and the star coupler provided two redundant paths of either 8 or 16 ports each. Digital's star coupler was developed for use with the VAX- and later Alpha-based computers running Digital's VMS operating system, to provide a passive, highly reliable interconnect for Digital's cluster technology.
