Abstract
A signal generator which can inject an optical signal into all the fibers of a cable, and so be left unmanned during jointing operations, uses a tungsten-halogen or other incandescent light source. This is collimated by conventional optical elements and pulsed by a mechanical chopper. All the fiber ends are aligned with and positioned within the chopped collimated beam.
Claims7
A signal generator for injecting a signal simultaneously into a multiplicity of optical fibers comprising an incandescent light source;
- at least one optical element for deriving from the source a light beam which will extend in a substantially rectilinear direction;
- means for aligning ends of a plurality of optical fibers with the direction of the beam and positioning them within the area of the beam;
- means for interrupting the beam at a substantially constant frequency to injet simultaneously a pulsed optical signal into all the said optical fibers.
A signal generator as claimed in claim one wherein the fiber and the aligning means is adjustable in two directions normal to one another and to the optical axis of the incandescent light source.
