Top Network Connector And Its Types You Probably Want To Know!

 

Network connectors

The piece of a link that plugs into a port or interface to associate one gadget to another is the network connector. Most connectors are either male (containing at least one uncovered pin) or female (containing openings in which the male connector can be embedded).

  In this content, we will explore the different types of connectors that are used in networking. These connectors will vary depending upon the type of network and the cable that they are attached to  Whether that cable is twisted pair, coaxial, telephone, or fiber optic. The types of network connectors are mentioned below:-

 

RJ-45:- 

      The RJ-45 is the most common network connector. This is an eight-pin connector that's used to connect computers and other network devices in a local area network. The RJ-45 is used with an unshielded twisted pair cable. The twisted-pair cable has eight wires and these wires are arranged in a certain order and then the wires are inserted into an RJ-45 connector and then are crimped on both ends using a wire crimper.  

After that one connector would be plugged into the computer's network card and then the other end would plug into a device, such as a switch, modem, or router. Then once that is done, the computer will be able to connect to a network. The RJ-45 has a single locking tab that locks itself into place.

 UTP coupler:- 

        UTP coupler is used for connecting UTP cables with RJ-45 connectors to each other.  This is typically used when running a longer cable is not an option. It's just used to extend a network cable by joining two cables together using their RJ-45 connectors. So you would just plug one end of the cable into the coupler and then you would plug in another cable on the other side. And now you have successfully extended your UTP cable. 

RJ-48:- 

          Another type of network connector that is similar to the RJ-45 is the RJ-48. The RJ-48 looks very similar to the RJ45, but the difference between the two is that the RJ-48 is used with shielded twisted pair cable instead of the unshielded twisted pair that's used with the RJ-45. The RJ-48 is primarily used with T1 lines and it's also wired differently than the RJ-45. 

 RJ-11 Connector:-

RJ-11 is a four-wire connector that's mainly used to connect telephone equipment. But as far as networking, the RJ-11 is used to connect computers to a local area network through the computer's modem. The RJ-11 locks itself into place by a single locking tab and it resembles the RJ-45 but it's a little bit smaller.

BNC Connector:-

The BNC connector is a type of  RJ connector that is used with coaxial cable. BNC stands for Bayonet Neill–Concelman. The BNC is used with both analog and digital video transmissions, as well as audio. Now, these connectors are not very common anymore but they can still be found on older networks. There are many different kinds of BNC connectors. Some examples of BNC connectors are:-

• BNC-T connector which connects three coaxial cables together.
• BNC coupler is used to connect two coaxial cables together.
• BNC terminator is used to terminating the ends of a cable.

F-type connector:-

This is a threaded connector typically used on coaxial cables. These are primarily used by cable providers to attach to cable modems. So if you have broadband cable, you will have a modem with a coaxial cable attached to an F-type connector that screws into the back of your modem that attaches with a nut. In addition to being used with broadband cable, they are also used with satellite internet. 

 USB connector:-  

The USB is very common on desktops and laptops. And because 'universal' is in its name, it can be used for many different purposes, including networking. So for example many manufacturers make USB wireless adapters that plug into a USB port on a computer to give the computer wireless network access. And there are also wired network adapters like where you would plug an ethernet cable at one end and then the other end into a USB port on a computer and then the computer will be able to access a network through its USB port.

fiber optic connectors:-

fiber optic networks use pulses of light to send data. There are many different types of fiber optic connectors, but in this content, we will only see the most popular fiber connectors. The main differences between these fiber connectors are the size and the method they use when coupling. Following are some types of fiber optic connectors:-

SC Connector:-

       The first fiber optic connector is called the SC or “standard connector”. This is often called the square connector. This was one of the first connectors to be used in the marketplace. This uses a push-pull connector, similar to audio and video plugs and these are commonly used between floors in a building.

MTRJ Connector:-  

The MTRJ  stands for “mechanical transfer register jack”. This is a fiber optic connector that uses a latched push-pull connection. It has a small form factor that's used for high pack density and it was designed to replace the SC connector. The MTRJ uses two fibers in a single design and it resembles the RJ-45. This connector is becoming increasingly popular in fiber networks today.

LC Connector:-

The next fiber connector is called the LC or local connector or Lucent connector since it was developed by Lucent. Now, this type of connector is also commonly used between floors in a building and it was designed to compete with the SC connector. It's about half the size of the SC connector which makes it better for highly populated racks and panels and this also uses a latch that locks itself into place similar to the RJ-45. 

ST Connector:-

 our last fiber optic connector is called the ST or straight tip. Now, this uses a half-twist bayonet type of lock and is commonly used with single-mode fiber optic cable. This is a large-size connector that was developed by AT&T. And because of its large size, its usage has declined in favor of smaller connectors, such as the LC and the MTRJ.

 just like UTP couplers, there are also fiber couplers. So if you wanted to join two fiber optic connectors, you would use a fiber coupler. Fiber couplers are used to join or couple two of the same fiber optic connectors and the two connectors have to be the same. These are not to be confused with fiber adapters, because fiber adapters are used for joining two different connectors together. 

Differences Between UPC AND APC

The difference between UPC and APC end faces or tips on fiber optic connectors.

For example, we're going to use a group of ST fiber connectors equipped with  UPC and APC end faces. Now when fiber optic connectors make a connection to each other, the point at which the connection is made is not perfect, because of the small imperfections of the flat surfaces. So what happens is at the point where the connectors join, light is transmitted from one connector to the other connector. But at the point where light passes to the other connector, the light will reflect back in the opposite direction towards the light source and when this happens, there is signal loss. And this is what happens in UPC connectors.

The light is reflected directly back. So as technology progressed, a new connector was developed to decrease the signal loss. And this new connector is called the APC connector.

 The difference between the UPC and the APC is the angle of the end face or tip where the connection is made. So as I said before, with the UPC, the light reflects back towards the light source. But with the APC, with its angled connection, the light doesn't reflect back towards the light source, it reflects back at an angle into the wall of the cable. And as a result, this greatly reduces the signal loss.
