As a result, using a WESS 8P8C crimp dieset on a TycoAMP 8P8C plug will crush the top of the connector, and vice versa.

These connectors are commonly used for Ethernet over twisted pair, registered jacks and other telephone applications, RS-232 serial using the EIATIA 561 and Yost standards, and other applications involving unshielded twisted pair, shielded twisted pair, and multi-conductor flat cable.

On the plug, these conductors are flat contacts positioned parallel with the connector body.

Inside the jack, the conductors are suspended diagonally toward the insertion interface.

When an 8P8C plug is mated with an 8P8C jack, the conductors meet and create an electrical connection.

The registered jack (RJ) standard specifies a different mechanical interface and wiring scheme for a true RJ45 than TIAEIA-568-B which is often used for modular connectors used in Ethernet and telephone applications.

P8C modular plugs and jacks look very similar to the plugs and jacks used for FCCs registered jack RJ45 variants, although the true RJ45 is not compatible with 8P8C modular connectors.

It is one of the many registered jacks, like RJ11, another telephone standard.

As a registered jack, telephone RJ45 specifies the physical male and female connectors as well as the pin assignments of the wires in a telephone cable.

The original RJ45 uses a special keyed 8P2C modular connector, with Pins 5 and 4 wired for tip and ring of a single telephone line and Pins 7 and 8 connected to a programming resistor.

It is meant to be used with a high speed modem, and is obsolete today.

However, near-identical physical connectors for computer networking became ubiquitous, and informally inherited the name RJ45 due to the overwhelming similarity.

While telephone RJ45 uses a keyed variety of the 8P body, meaning it may have an extra tab that a computer RJ45 connector is unable to mate with, the visual difference from an Ethernet 8P is subtle.

True telephone RJ45 connectors are a special variant of 8P2C, meaning only the middle 2 positions have conductors in them, while pins 7 and 8 are shorting a programming resistor.

Electronics catalogs not specialized to the telephone industry advertise 8P8C modular connectors as RJ45.

Virtually all electronic equipment that uses an 8P8C connector (or possibly any 8P connector at all) will document it as an RJ45 connector.

In common usage, RJ45 also refers to the pin assignments for the attached cable, which are actually defined in the wiring standard TIAEIA-568-B.

This standard does not use the short term 8P8C and covers more than just 8P8C modular connectors, but the 8P8C modular connector type is the eight position connector type described therein, with eight conductors installed.

A cable that is wired as T568A at one end and T568B at the other (Tx and Rx pairs reversed) is a crossover cable.

Before the widespread acceptance of auto-MDIMDIX capabilities a crossover cable was needed to interconnect similar network equipment (such as hubs to hubs).

Crossover cables are still used today to connect two computers together without a switch or hub.

A cable wired the same at both ends is called a patch or straight-through cable, because no pinpair assignments are swapped.

While both types look remarkably similar, the tooling used to install the two different plug types is mutually exclusive and cannot be interchanged between the two types.

WESS compatible plugs are available from a large number of manufacturers, whereas TycoAMP plugs are produced exclusively by Tyco Electronics.

Both types of modular plugs will plug into the same standard 8P8C modular jack.
