MPOs with 8, 12 or 24 fibers have a connector key in the center. P1 to P12 on the first row and P13 to P24 on the second row. For MPO connectors with multiple rows, numbers also follow from top to bottom, i.e. When the connector key faces up (referred to as “key up”), the positions of the fibers within the connector run in a sequence from left to right from position 1 (P1) to position 12 (P12). The role of the alignment pins is to ensure that fibers are facing each other perfectly.Ĭonnector key-MPO connectors have a key on one side of the connector body. Mating only male connectors with female connectors is primordial to avoid damages (male-on-male) and ensure continuity. Male and female connectors-Unlike single-fiber connectors, which are all male, MPO connectors can be male (with pins) or female (with corresponding guiding holes).
Illustrated here are the three standardized fiber-polarity types: Type A (commonly called straight-through), Type B (commonly called inverted), and Type C (commonly called twisted-pair). Additionally, the MPO-32 is made up of two rows of 16 fibers each. The MPO-16 also exists on the market, made up of one row of 16 fibers. More and more, CORDs are using the MPO-24. Higher-density connectors also exist, composed of several rows of 12 fibers (e.g., 24, 36, 48). The most common type of connector is the MPO-12, which has one row of 12 fibers. That’s why some manufacturers introduced Erika Violet-colored connectors for OM4, to distinguish them from aqua OM3.Ĭonnector types-Each jacket houses multiple fibers that are also color-coded based on a common standard. However, having one color (aqua) for two different specifications can be confusing.

Multimode multifiber connectors have flat ferrules (also referred to as PC or UPC), and the recommended cable jacket colors are aqua for OM3 and OM4, and lime for OM5. Because yellow represents either OS1 or OS2 specifications, it’s important to read the cable specifications carefully. Singlemode multifiber cable jackets are yellow, and they generally come with angled physical contact (APC) connectors. MPO connectors are made for both singlemode and multimode multifiber cables. MPO connector designĬolor coding-MPO connectors can be color-coded to help you easily distinguish between the different types and specifications. Today, CPU sockets are used instead of CPU slots, but expansion slots are still used for expansion cards.Automated fiber-endface analysis eliminates guesswork, complies with applicable standards, and provides consistent results regardless of experience. SlotĪ slot is also a connection used with computers that describes a CPU slot or an expansion slot. For example, the Socket 370 is a socket that supported the first Intel Celeron processors and Coppermine processors. Each socket supports a set of computer processors. Over the evolution of computers, many different sockets were designed for computers. A socket example is a CPU socket, a socket on the motherboard for a computer CPU. SocketĪ socket is an opening that fits another specific device with matching pins or other connectors. For example, an AC adapter used with laptop computers and other devices takes AC power and converts it into DC power. AdapterĪn adapter is a device capable of converting power or data from one source of input into another. With computers, a jack often describes an audio jack.

The port has holes or a slot that matches the plug or card connected to the port.
For example, the end of a USB cable has a connector to connect to a USB port. When referring to cables, the connector is the end of the cable that connects to a port. For example, all desktop computer expansion cards have a connector that allows them to connect in a slot on the motherboard. ConnectorĪ connector is the unique end of a plug, jack, or edge of a card that connects to a port.
WireĪ wire is a single strand of metal (e.g., copper) or optical fibers capable of transmitting power or data from one area to another. See our cable definition for a list of cables used with computers. The picture is an example of a Cat 5 network cable. Cable and cordĪ cable or cord is one or more wires in a plastic covering that allows power or data transmission between devices. In our example of a power cord plug, this plug is different in different countries around the world.
