Quote from article: To support Gigabit Ethernet, a higher performance version of cat 5, enhanced cat 5 or cat 5e has been added to the standards. Cat 5e adds new performance requirements to permit higher speed network operation In real life depending on the length your throughput for 5 will be far less than 5e. - -- Joseph Loo [email protected] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJU5WROAAoJEEMx95CapKFE8m0P/0LJYyO4QRBtofwJj8iqzSQL gNV6ET3dLe77Ig5bmNVXrMxw+8O1ipcM1SePFFsYg+C9oFb3/a9YmYXsvaWs0bmT juaIUFfyAMImxN+GyTJhGxGoj9EEdjTvXHo1TBCIP1BRh5m2KkqwZjuxsDpJz3yu JMRxDe8iqN8BdHJn3BAAUxS84CGuHJ1fi9jZoOSjjRp76665Zqd8hijW13hqpdCC +uJzyzvYYgd5tV7avedVFNxGe3kEQJmP7UiMHQ1entY+ERAv4Km+v7t7Yt+ZhUyc TPBLzW7gvO/+WlT25y89SbFXAJxRSSnUdw0zXaslySHg7LzPZUV4UYyP+IvNuJjo I/qWEoMVfGsLWCB8QsVOckE2wm7VBqnWoRxlnuDb5QXFam1L2NHZn5CK6QpC6pw9 NWOk55u5CDjxpM5X9ia04iNkDyaecIM0ELvX2XS1xLug4DucnHMN7tIAHixcDqUv mhkeuYrvnaT/vPTrFAkTty9WzK+GYOomi1nNPlDYBT8lou5OdJmtYxulq1zUf4vv 1wUFvLflIfnRpPY78h2yjh99Atenxu4Kc+a+WeiBhg4gaINzeks7r1f1ynGhokdH yPQ24uFBM4tkDgduisdVYktjL4iXYI0Ako6lhY0119Ovl1QPbg0hZQvcgyCZEX6N PxbZp2Mf4jfHxBqoxcOT =jr63 -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
