How many conductors are there on an rj45?
An RJ45 connector has 8 conductors. it has the naming convention of 8P8C (8positions 8conductors).
The 45 indicates the jack number; RJ45 indicates Registered Jack number 45. However, there is a slight complication - what most people call RJ45 should actually be 8P8C. The RJ numbers used to be allocated by the FCC, but they are now defined by Administrative Council for Terminal Attachment (ACTA).
