Both RJ48 and RJ45 use the 8P8C modular plug and 2 pairs of the wires, one pair for transmitting and one pair for receiving data. The RJ45 that we are already very familiar with uses the pins 1,2,3, and 6 for receiving and transmitting data. With RJ48, there are a few configurations that can be used depending on the situation and how they are to be used. One configuration uses the pins 1,2,4, and 5 while another uses 1,2,7, and 8. Other wires are also used for extra shielding while the remaining wires are reserved in case some uses would arise in the future.
RJ45 is used mainly in local area networks where the distances between each network element is relatively short. It uses the more common UTP or Unshielded Twisted Pair that have categories 1 to 6, with cat5e being the most predominantly used.
RJ48 is used in T1 data lines where the wires can extend longer distances and are often exposed to the environment. To protect the integrity of the signal, RJ48 wirings use STP or Shielded Twisted Pair cables.
RJ45 and RJ48 use the same connector
RJ45 differs from RJ48 in the way they are wired
RJ45 is predominantly used in LAN while RJ48 is more commonly seen on T1 lines
RJ45 is connected with UTP cable while RJ48 uses STP
