  • High-speedinterconnects within/between switches, routers and transport equipment
  • Server-serverclusters
  • Super-computinginterconnections

Interconnects rack-to-rack, shelf-to-shelf, board-to-board, board-to-optical backplane

ABSOLUTE MAXIMUM RATINGS (TC=25°C, UNLESS OTHERWISE NOTED)
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings will cause permanent damage and/or adversely affect device reliability.
