Gigabit ethernet LAN cable requirement

請問各師兄姐, 行Gigabit ethernet 用 Cat5 (唔係Cat5e)線得唔得, 如果得, 有冇長度限制?

Category 5 and 5e cables
http://www.mandmmaintenance.co.u ... -cat6a-cabling.html
The original Category 5 (CAT5) cables consist of 4 pairs of twisting copper wiring. They are rated at transmitting signals of up to 100 MHz. They were originally rated for use in Ethernet networks running at 100 Mbit/s. Newer Gigabit (or 1000BASE-T) Ethernets were designed to work with CAT5 cables as well.

In 2001, Category 5e (CAT5e) cables were introduced. These cables are basically the same as CAT5 cables except that there is less data signal loss. This data loss comes from electrical interference (called crosstalk) coming from neighbouring wire pairs, other nearby electrical wiring, or the devices the cable was attached to.

cables are still limited to a maximum of 100 m (328 ft) in length (normal practice is to limit fixed ("horizontal") cables to 90 m to allow for up to 5 m of patch cable at each end
