Deployment configurations •
•
Define a 2.5 Gb/s PHY for operation over , 1 ‒ Up to at least 100m on four-pair Class D (Cat5e) balanced copper cabling on defined use cases and deployment configurations Define a 5 Gb/s PHY for operation over ‒ Up to at least 100m on Class E (Cat6) balanced copper cabling on defined (2) use cases and deployment configurations ‒ Up to 100m on Class D (Cat5e) balanced copper cabling on defined use cases and deployment configurations
1) Use cases and deployment configurations for 2.5 Gb/s PHY for operation over ‒ Up to at least 100m on four-pair Class D (Cat5e) balanced copper cabling 2) Use cases and deployment configurations for a 5 Gb/s PHY for operation over ‒ Up to at least 100m on Class E (Cat6) balanced copper cabling 3) Use cases and deployment configurations for a 5 Gb/s PHY for operation over ‒ Up to 100m on Class D (Cat5e) balanced copper cabling •
Use case based deployment configurations not required for PHYs demonstrating operation over “worse case” cabling configurations. 4
