Modular jacks (MJ) connectors and cables are broadly used to bring Ethernet signal up to 10 Gb/s depending on the category of the product. It is also possible to deliver power through it with PoE. In this episode, we will study if recommendations for the WE-MJ connectors can be extended up to Type 4 and demonstrate the capabilities of modular jacks in case they are accidently used as a disconnector product in a PoE application.
