Modular jacks connect electrical devices to outlets. It’s important to select the correct type for the job. They come in different types such as telephone, computer, and ethernet jacks. Modular jacks have a special code and are referred to as “male” or “female”.
Modular jacks are the actual physical components that connect electrical devices, such as telephones and computers, to their outlets. Before plugging in any electronic equipment for home or office use, it’s important to select the correct modular jack for the job. Once a technician has identified the type of modular jack needed based on the equipment being connected, the equipment will function properly under normal conditions and use. Modular jacks come in a wide range of different types from modular connectors and plugs, telephone jacks, computer and ethernet jacks, internet connections and electronic components.
In many buildings, the most common form of modular jack is the electrical connection, cord, or plug. Outlets that supply electricity to electrically powered devices connect them via a wire or cable that snaps together in a special modular termination, like a set of metal prongs found on average electrical wire. Once the prongs are inserted correctly into the associated socket, electrical energy is transferred from the socket to the device and it is ready for use. The modular jack must match the socket for this power exchange to occur.
Another very common type of modular jack is a telephone or Ethernet jack. This small unit is connected to a telephone cord which then transmits an analog telephone signal from a special telephone jack placed on a wall, desk or cubicle to the actual telephone unit. If the telephone grip becomes loose or is removed from the telephone socket for any reason, the signal is lost and telephone calls cannot be made. Telephone jacks are usually small square attachments made of plastic that contain small wires inside and a release tab.
A third type of modular jack belongs to personal computers that can be connected to a local or worldwide network, such as the Internet. While older desktop computers or those that connect to an internal network may connect through a telephone jack which sends a signal down telephone lines facilitated by the use of a dial-up modem, many computers use cable or digital signals to connect to the Internet . In some cases, the signal can also be sent wirelessly via a router, which is connected to this modular jack with a special cable.
Modular jacks are used extensively in many buildings around the world due to their ease of use. They are an economical alternative to direct wiring of electronic devices. All modular jacks have a special code established by the registered jack system and will display a numeric and letter code so that electronics engineers can choose the right type for each unit. Also, modular jacks are referred to as “male” or “female” depending on whether they will be plugged or if a component will be plugged into them.
