Yeah
The maximum is 1 Gbps (CAT-5e, CAT-6), the maximum distance without attenuation is 100 m.
ANSI/TIA-568-C.2 This standard specifies characteristics for cabling such as Cat-5e, Cat-6, and Cat-6A
Category 5e or Category 6
Yes, CAT 5E is well-suited for gigabit ethernet. CAT 6 will also work just fine.
Either Cat 5 or 5e is most common at this point, although Cat 6 is becoming more prevalent.
The maximum segment length specified by the 1000BASE-T standard is 100 meters (328 feet) when using Category 5e (Cat 5e) or higher unshielded twisted pair (UTP) cabling. This length includes the total length of the cable run from the switch or router to the endpoint device, accounting for any patch cables used in the installation.

The transmission speed of the cable is limited in most cases by the hardware attached to it. Cat5 basic cable has been used successfully up to 1 gigabit speed using ethernet. There have been lab tests proving it might be useful for 10gigabit over short ranges but usually that requires Cat5e or Cat6 grade cable. The most common speeds are 10/100 mb ethernet.
Characteristic impedance of cat 5e utp cables is 100 ohms.
The primary dis-advantage is the physical installation of CAT [5e/6] cabling and faceplates. CAT cables are installed in parallel in a star network unlike normal telephony where cables are in series thus less obtrusive.
There is a cat-5 crimping tool needed to attach plugs to the ends of the cables. It is also advised to test your cables with a cable tester, but this can also be done by simply plugging it into a computer & switch.
