What are the steps in crimping RJ-45 connector?

  

 Crimping RJ-45 connectors onto CAT-5 cable can be frustrating. Some techniques make the process of installing RJ-45 connectors easier. You can quickly and easily crimp an RJ-45 to a cable with or without a crimping tool. If you have a crimping tool, strip away a portion of the sheath, untangle and arrange the wires in the correct order, fit them into the connector, and use the crimping part of your tool to squeeze the small pins into the wires and secure the connector. If you don't have a crimping tool, no problem!Use a pair of scissors or a utility knife to cut away a section of the sheathing at the end of the cable, untwist and arrange the small cables in the right order, put them into the RJ-45 connector, and use a small, flathead screwdriver to press down each of the pins.

Method 1:  Using a Crimping Tool

Strip the cable back 1 inch (25 mm) from the end.  Insert the cable into the stripper section of the tool and squeeze it tight. Then, rotate the crimping tool around the cable in a smooth and even motion to create a clean cut. Keep the tool clamped and pull away towards the end of the wire to remove the sheathing. 

• The stripping section is a round hole near the handle of the tool.
• The sheathing should come off cleanly, leaving the wires exposed

Method 2:  Untwist and straighten the wires inside the cable.

 Inside of the cable you'll see a bunch of smaller wires twisted together. Separate the twisted wires and straighten them out so they're easier to sort into the right order. 

• Cut off the small plastic wire separator or core so it's out of the way.
• Don't cut off or remove any of the wires or you won't be able to crimp them into the connector.

Method 3:  Arrange the wires into the right order.

Use your fingers to put the wires in the correct order so they can be properly crimped. The proper sequence is as follows from left to right: Orange / White, Orange, Green / White, Blue, Blue / White, Green, Brown / White, Brown. ^[3]

• There are 8 wires in total that need to be arranged in the right sequence.
• Note that the wires labeled Orange / White or Brown / White indicate the small wires that have 2 colors.

Method 4:  Cut the wires into an even line  1/2  inch (13 mm) from sheathing.

Hold the wires with your thumb and index finger to keep them in order. Then, use the cutting section of the crimping tool to cut them into an even line. 

• The cutting section of the tool will resemble wire cutters.
• The wires must be in an even line to be crimped into the RJ-45 connector properly. If you cut them in an uneven line, move further down the wires and cut them again.

Method 5:  Insert the wires into the RJ-45 connector. 

Hold the RJ-45 connector so the clip is on the underside and the small metal pins are facing up. Insert the cable into the connector so that each of the small wires fits into the small grooves in the connector.

• The sheathing of the cable should fit just inside the connector so it's past the base.
• If any of the small wires bend or do not fit into a groove correctly, take the cable out and straighten the wires with your fingers before trying again.
• The wires must be inserted in the correct order and each wire must fit into a groove before you crimp the connector.

Method 6:  Stick the connector into the crimping part of the tool and squeeze twice.

Insert the connector in the crimping section of the tool until it can't fit any further. Squeeze the handles to crimp the connector and secure the wires. Release the handles, then squeeze the tool again to make sure all of the pins are pushed down.

• The crimping tool pushes small pins in the grooves down onto the wires to hold and connect them to the RJ-45 connector.

Method 7:  Remove the cable from the tool and check that all of the pins are down.

 

Take the connector out of the tool and look at the pins to see that they're all pushed down in an even line. Lightly tug at the connector to make sure it's attached to the cable.

• If any of the pins aren't pushed down, put the wire back into the crimping tool and crimp it again.

What are the types of Network Cable?

 Network cables are used to connect and transfer data and information between computers, routers, switches and storage area networks. These cables are essentially the carrier or media through which data flows. Twisted pair cable is used in many ethernet networks. 

Four Types Of Network Cabling

  Network cable acts like a medium through which information travels from one network device to the other. The type of cable selected for a network depends on the network's size, topology, and procedure. The various types of network cables act as the backbone of the network infrastructure.

  Selecting the correct type of network cabling  can effect various business functions because enterprise network admins employ new technologies. The type of network cable used in any network infrastructure is one of the most vital aspect of networking in various industries.

Coaxial Cable

   It has a single copper conductor in the middle. A plastic layer provides insulation between the braided metal shield and center conductor. The metal shield blocks outer interference from motors, fluorescent lights, and other computers.

  Coaxial cabling is extremely resistant to signal obstruction though it is complex to install. It can handle great cable lengths between network devices than the twisted pair cable. The two types of coaxial cables are thin coaxial and thick coaxial.

Shielded Twisted Pair (STP) Cable

   It is a special kind of copper telephone wiring used in business installations. An external shield which functions as a ground is added to the normal twisted pair telephone wires. Shielded twisted pair may be the answer if you want to place the cable in an area with potential interference and risk to the electrical current in the UTP. Shielded cables can also help in expanding the distance between the cables.

Fiber Optic Cable

  Fiber optic cabling consists of a center glass core surrounded by many layers of protective materials. It removes the problem of electrical obstruction by transmitting light rather than electronic signals. This makes them perfect for certain atmospheres which contain huge amount of electrical interference. It has become the standard for connecting networks between buildings because of its resistance to lighting and moisture.

Unshielded Twisted Pair

It is the most admired type of network cable in the world. UTP cable is used for both conventional telephone and computer networking.  

The various wiring schemes for UTP are:

• CAT1 which is used for telephone wire. CAT2 supports speeds up to 4 Mbps and used frequently for token ring networks.
• CAT3 and CAT4 are both used for Token Ring networks for higher network speeds.
• CAT5 wire is now replaced by the CAT5e designs providing an enhanced crosstalk specification allowing it to support speeds up to 1 Gbps. It is the most used network cabling specification in the world.
• CAT6 support speeds of 1 Gbps for length up to 100 meters and 10 Gbps up to 55 meters. Organizations using CAT6 cabling should use a specialized cable analyzer to request a complete test report, to ensure that the CAT6 guidelines and standards have been followed during the installation.
• The CAT7 is a fresh copper cable pattern which can support speeds of 10Gbps and length up to 100 meters.
