About 1000BASE-T1 1000BASE-TX and 100BASE-T1
100BASE-T1
The 100BASE-T1 Physical Layer supports standard media access controller (MAC) interfaces via the MII.Each copper port supports a single balanced twisted-pair link segment connection up to 15 m in length. 100BASE-T1 provides data rate of 100 Mb/s at the MAC interface over a single balanced twisted-pair cable.
The architectural positioning of the 100BASE-T1 Physical Layer is depicted below:
1000Base-T
4 Use all alignment （ full duplex ） Full duplex operation of network equipment requires crosstalk / Echo cancellation technology super 5 Class and higher cabling systems can support 4 Level code （PAM-5） Each signal level represents 2 The bit Send... Every second 125M Symbol And 100Base-Tx The symbol rate is the same Reduce noise interference Support for each pair of lines 250Mbps The data rate of （ Every direction ）1000BASE-T Using unshielded twisted pair as transmission medium, the longest transmission distance is 100 rice
