The fibre optics are bundled inside a robust plastic casing which connects the response device to the optoelectronic interface unit. It is easily passed through a standard wave guide in the penetration panel and needs no special filtered connectors or complicated installation.
The fibre optic bundle is used to connect the response device to the electronic interface.
The 8-fibre bundle is for use with the 904 interface and 2 or 4 button response pads. The 12-fibre bundle is for use with the 905 & 932 intefaces and all response pads. The length of the bundle is determined by the distance from the control computer to the scanner: 55 ft. is the standard length and works in most settings. 80 and 100 ft long bundles are also available when needed.
