A.1.2 Twisted Pair Requirements
Length
10BASE-T transceivers must be able to transmit over a 100
meter link (328 feet) using 24 AWG unshielded twisted pair
wire. 10BASE-T specifies no maximum link length.
Due to cable delay, the maximum link length is always
limited to about 200 meters (656 feet), regardless of the type
NOTE
of cable.
Generally, you can achieve links of up to 150 meters (492 feet)
for unshielded and shielded twisted pair cable. For each
connector or patch panel, subtract 12 meters (39.4 feet).
