Difference Between RJ45 and RJ11

The main visual difference between the two connectors is that RJ45 is wider since it comprises eight wires, while the RJ11 has four. ... If you plug an RJ11 plug into an RJ45 jack, for example, it can potentially damage the equipment. Different Applications The RJ45 is commonly used for LAN and ADSL connections.

Can I use RJ45 instead of RJ11?

Because of dimensional differences between the two (RJ11 is a 4 or 6-pin and RJ45 an 8-pin connector), it is obvious that an RJ45 plug cannot be used in an RJ11 socket.

Which is better RJ11 or RJ45?

The main difference between these two is in where they are actually used. RJ45 jacks are used in networking (Ethernet LAN), where you connect computers or other network elements to each other. RJ11 is the cable connector that is being used in telephone sets.

What are RJ 45 and RJ-11 connectors?

RJ45 is used with ethernet cables. RJ11 is used with telephone cables. RJ45 is larger in size. RJ11 is comparatively smaller in size.

Is Ethernet RJ11 or RJ45?

Telephones use an RJ11/RJ12 connector whereas Ethernet uses RJ45. RJ11/RJ12 only uses 4-6 pins whereas RJ45 uses 8 pins.

Are all RJ45 connectors the same?

They are exactly the same physically. Just beware that Gigabit ethernet use all pairs while 100Mbit Ethernet does not. Therefore if you have crappy connectors and/or cables, they may only support 100Mbit.

Can I use an RJ45 for phone?

If you have a two line phone, you can plug it directly into a T568A wired jack and both lines will work. The smaller RJ11/12 plugs will fit directly inside an RJ45 jack. It's not preferred since you might damage the other pins but it is designed to work that way.

Can you use RJ11 for Internet?

Only a Modem & Modem+Router can have RJ11 port. If your router's​ wan port is RJ45 then it can only act like a router and can't work with with RJ11. For RJ11 you need a modem.. ... With A proper Modem and Router it will work.

Why RJ45 is called RJ45?

Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are sometimes also called RJ45 cables. The "RJ" in RJ45 stands for "registered jack," since it is a standardized networking interface. The "45" simply refers to the number of the interface standard.

How many wires does a RJ11 have?

The typical RJ-11 connector has six terminals. Usually, only the middle four pins are used. The POTS (Plain Old Telephone Service) residential telephone wiring generally contains two pairs of wires - designed for two separate telephone lines.

What is RJ 11?

(Registered Jack-11) A telephone interface that uses a cable of twisted wire pairs and a modular jack with two, four or six contacts. RJ-11 is the common connector for plugging a telephone into the wall and the handset into the telephone. See modular connector.

What is RJ in RJ45?

A registered jack (RJ) is a standardized physical network interface for connecting telecommunications or data equipment. ... The most common twisted-pair connector is an 8-position, 8-contact (8P8C) modular plug and jack commonly referred to as an RJ45 connector.

What are the different types of RJ connectors?

RJ11, RJ14, RJ25 wiring

RJ11, RJ14, and RJ25 all use the same six-position modular connector, thus are physically identical except for the different number of contacts (two, four and six respectively) allowing connections for one, two, or three telephone lines respectively.
