CABLE LENGTH DETERMINATION USING VARIABLE-WIDTH PULSES |
摘要 |
A method of determining the length of a cable coupled to a transceiver of a network device includes transmitting a first series of pulses of a first pulse width onto a cable, receiving reflections of the first series of pulses, transmitting a second series of pulses of a second pulse width onto the cable, and receiving reflections of the second series of pulses. The second pulse width is wider than the first pulse width. It is determined whether the reflections of the first series of pulses satisfy a criterion. The length of the cable is calculated using either the reflections of the first series of pulses or the reflections of the second series of pulses, based at least in part on whether the reflections of the first series of pulses satisfy the criterion. |
