Patent number: 11216325Abstract: Embodiments of the present disclosure provide a method and apparatus for reducing cross talk among pins in a connector. The apparatus may detect a bit error rate (BER) for each of a plurality of pins in a connector and compare the BER for each pin to a threshold BER. Responsive to determining that a set of pins among the plurality of pins each have a BER that is above the threshold BER, the apparatus may decrease the BER for each pin in the set of pins by selecting a subset of pins among the plurality of pins and adjusting operational characteristics of one or more of the subset of pins. The operational characteristics include a transmit power of the pin.Type: GrantFiled: June 28, 2019Date of Patent: January 4, 2022Assignee: Arista Networks, Inc.Inventors: Ankush Dhar, Harold Wang, Prasad Venugopal, Arul Ramalingam
