Abstract

A method (300) of operating a fibre optic network (100), said network comprising: a terminal laser for transmitting a first optical signal having a first pulse width; an Optical Time-Domain Reflectometer (120), OTDR, for measuring the first optical signal thereby to perform diagnostics upon the fibre optic telecommunications network; at least one Optical Network Unit (160), ONU; an optical signal generator (170), arranged between the OTDR and the at least one ONU, and comprising: a photosensor (230) for sensing the first optical signal from the terminal laser; and a light source (270) for transmitting a second optical signal to the at least one ONU, the second optical signal having a second pulse width; the method comprising the steps of: transmitting, by means of the terminal laser, the first optical signal to the optical signal generator (310); detecting, by means of the photosensor, the first optical signal (330); transmitting, in response to said detecting, and by means of the light source, the second optical signal to the at least one ONU (340), wherein the second pulse width is shorter than the first pulse width.
