Many applications that originally used a bulkier, more expensive connector have converted to modular connectors. The special plugs are preferred for test equipment and adapters, which may be rapidly connected to a large number of corresponding connectors in quick succession for testing purposes. The remaining brown pair is increasingly used for Power over Ethernet PoE.
The formal approach to connect telephony equipment is the insertion of a type-approved converter. The standard orientation for installing a jack in a wall or panel is with the tab down.
Modular plugs are described as containing a number of potential contact positions and the actual number of contacts installed within these positions. Connected pins on plug and jack have the same number. However, protective boots or rigid protective ramp adapters are available which can be snapped over an installed unprotected modular plug. This practice is followed by electronics catalogs and many electronic equipment manuals.
The crimper may also permanently deform part of the plastic plug body in such a way that it grips the outer sheath of the cable for secure fastening and strain relief. Labels and manufacturer's documentation should be consulted whenever an unfamiliar connector is first encountered. Computer connectors Ethernet Modularity Networking hardware Telephone connectors. These actions permanently attaching the plug to the cable.
Motorola uses the pin connector as a microphone connector in several of their mobile radio product lines. As the die compresses, these teeth force the plug contacts into the conductors of the cable being terminated. Frequently the pinout is different, usually mirrored i. The crimping tool contains a die which is often exchangeable and is closely matched to the shape and pin count of the modular plug.
Audio and video interfaces and connectors. This means that field retrofitting of these types of boots is not possible. The drawings to the right show that the copper connections and pairing are the same, the only difference is that the orange and green pairs colors are swapped. Use of the special plugs avoids inadvertent damage to the equipment under test, even when a narrower plug is inserted into a nominally incompatible wider jack. The molded plastic bodies of the special plugs may also be colored with a light blueish tinge, to aid in quick recognition.
There is now a standardized wiring scheme for Power over Ethernet. The connector wiring on the Apple computers, however, required a polarized straight through pinout. This was necessary to preserve the electrical properties of those pairs for Ethernet, tratat de istoria religiilor mircea eliade pdf which operates at much higher frequencies than analog telephony. Termination of cables with modular connectors is similar across the various number of positions and contacts in the plug.
Electrical connector commonly used in telephone and computer networks. The latching tab may easily snag on other cables and break off resulting in loss of the secure latching feature. The connector body positions with omitted or unconnected contacts are unused for the electrical connection, but ensure that the plug fits correctly. From Wikipedia, the free encyclopedia. Plugs are used to terminate cables and cords, while jacks are used for fixed locations on surfaces of walls, panels, and equipment.
These special plug connectors can be visually identified by carefully looking for the extra slots molded into the plug. Contacts are numbered by the contact position.
It was intended for high speed modems, and is obsolete. The dimensions of modular connectors are such that a narrower plug can be inserted into a wider jack that has more positions than the plug, leaving the jack's outermost contacts unconnected. In other projects Wikimedia Commons. This is not really the correct moniker, although it is in very common use.
For example, a Modified Modular Jack using an offset latching tab was developed by Digital Equipment Corporation to prevent accidental interchange of data and telephone cables. Inside the jack, the contacts are metal spring wires arranged at an angle toward the insertion interface. Most protective boots must be installed onto a cable before the modular plug is crimped on. When the plug is mated with the jack, the contacts meet and create an electrical connection. Excessive resistance may be encountered when inserting an incompatible plug, as the outermost contacts in the jack are forcibly deformed.

Wikimedia Commons has media related to Modular connectors. Unshielded and shielded twisted pair cabling standards.
The means of indexing may be non-standard cross-sectional dimensions or shapes, retention mechanism dimensions or configuration. The cable between the computer and the keyboard was a coiled cord with an appearance very similar to a telephone handset cable.
Probably the best known applications of modular connectors are for telephone and Ethernet. The spring tension of the jack contacts ensures a good interface. On the plug, the contacts are flat metal bars positioned parallel to the connector body. When not installed, contacts are usually omitted from the outer positions inward, such that the number of contacts is almost always even.
Other than telephone extension cables, cables with a modular plug on one end and a jack on the other are rare. If an inserted plug lacks slots to accommodate the jack's contacts at the outermost extremes, it may permanently deform those outermost contacts of an incompatible jack. Such connectors can be adapted for use with a computer serial port so that control commands may be sent from the computer to the set top box.
