The difference between RJ45 and RJ48

The difference between RJ45 and RJ48


RJ45 and RJ48 are similar in appearance and structure, both are 8-pin positions, and the applications are different.


RJ45 is used for Ethernet (10/100/1000/10G UTP/STP) interface, which is the network cable interface on our usual computers, routers, etc.


Usually 10/100M Ethernet uses (1-2) (3-6) pins, and 1000M/10G Ethernet uses (1-2) (3-6) (4-5) (7-8) pins .


RJ48 is used for T1, E1 serial lines, using shielded twisted pair cables, commonly RJ-48C and RJ-48S. The pins used are (1-2) (4-5), and occasionally some (3-6) are connected to SHIELD/GND/RETURN.
