Glossary

A connector containing both fiber and electrical connectivity.

Hybrid networks use a combination of any two or more topologies in such a way that the resulting network does not exhibit one of the standard topologies (e.g., bus, star, or ring). A hybrid topology is always produced when two different basic network topologies are connected.

Optical signal loss (attenuation) resulting from hydrogen found in the optical fiber. Hydrogen in glass absorbs light and turns it into heat and thus attenuates the light. For this reason, glass manufacturers serving the fiberoptic industry must keep water and hydrogen out of the glass and deliver it to guaranteed specifications in this regard. In addition, they must protect the glass with a cladding that will preclude the absorption of water and hydrogen into the glass.

A DuPont trade name for a synthetic rubber (chlorosulfonated polyethylene) that is used as insulating and jacketing material for cabling.

Symbol used to designate current.

Used to connect IBM Token Ring stations using Type 1 shielded twisted-pair 150 ohm cable. This connector has both male and female components, so every IBM data connector can connect to any other IBM data connector.

Insulation Displacement Connector - Usually for flat ribbon cable. A type of connector which attaches to a cable by using metal prongs to pierce the cable's outer insulation and make contact with the inner conductor.
Also contacts on RJ45 sockets and many telecom devices are connected via IDC contacts.

IEC (International Electrotechnical Commission)
A range of standardised power connector’s used to connect devices to the mains supply. (i.e. Kettle Lead)

Also known as IEC C13 SOCKET, IEC 320,  C13 Female, CEE 22 or Kettle connector.
The 3-pin 10 AMP Power socket, referred to as a kettle type connector used to connect the mains supply to equipment.
The C13/C14 connectors are six sided (a rectangle with the top corners beveled off) and the pins are vertical mounted parallel to the shorter sides.

Also known as IEC 320 C14 Male, CEE 22 or Kettle connector.

The 3-pin 10 AMP Power plug used for most household power leads. The kettle type plug that is used to connect the mains supply to the computer. (see Kettle Lead)

The C13/C14 connectors are six sided (a rectangle with the top corners beveled off) and the pins are vertical mounted parallel to the shorter sides.

Also known as IEC 320 C15 Female, Hot Condition,
3 Pin contact socket 10 AMP

Also known as IEC 320 C16 Male, Hot Condition, 3 Pin contact socket 10 AMP.

Also known as IEC 320 C19 Female.

The C19 16 AMP 3-pin socket is a rectangular shape with slightly rounded corners the pins are horizontally mounted parallel to the longer sides of the connector.

Unlike the C13/C14 connectors the C19/C20 pins are horizontally set and so easy to tell apart.

Also known as IEC 320 C20 Male.
The C20 16AMP 3-pin Plug is a rectangular shape with slightly rounded corners and the pins are horizontally mounted parallel to the longer sides of the connector.
Unlike the C13/C14 connectors the C19/C20 pins are horizontally set and so easy to tell apart.

C5 socket, often referred to as Mickey Mouse or Clover Leaf.

3 Pin IEC connector 2.5 AMP
