FAQ:

Q: What’s the difference between RJ45 and CAT5?

A: RJ45 is the electrical interconnection standard that defines the connector and how the wires are arranged at the end of the cable while CAT5 is a standard regarding Ethernet cables.

Q: What is the purpose of a RJ45 connector?

A: In modern domestic and commercial environments, RJ45 connectors are primarily used for plugging an internet-enabled device directly into hardware such as a modem, router, or server. The connectors themselves are the modular sets of fittings at either end of the physical data connection (Ethernet cable) joining one networked device to another.

Q: Where is the RJ45 connector commonly used?

A: RJ45 is a type of connector commonly used for Ethernet Networking (UTP Cable – Cat5, Cat6). Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are sometimes also called RJ45 cables.

Q: How many types of RJ45 connectors?

A: Generally, there are two types of Rj45 cable connectors: the standard patch cables and the crossover cables. Standard patch cables are used to connect a cable modem to a router or to a switch, or to connect a computer to a network router/switch.
