 | RJ45 (Cabling standards)
The standard data connector for structured wiring installations. RJ45's are available in UTP (Unshielded twisted pair) & STP (Shielded twisted pair) varieties. |
 | BNC ("Bayonet Neil Concleman" or "British Naval Connector") The "Bayonet Neil-Concelman" or "Bayonet Navy Connector" or "Baby Neil Connector," depending on the information source. Karl W. Concelman is believed to have created the "C" connector. The BNC was designed for military use and has gained wide acceptance in video and RF applications to 2 GHz. The BNC uses a slotted outer conductor and some plastic dielectric on each gender connector. This dielectric causes increasing losses at higher frequencies. Above 4 GHz, the slots may radiate signals, so the connector is usable, but not necessarily mechanically stable up to about 10 GHz. Both 50-ohm and 75-ohm versions are available. TNC connectors are of miniature size like the BNC connector but feature a threaded coupling nut for applications requiring performance through 11 GHz. Chosen for their durability and reliability, TNC connectors are widely used in the cellular / mobile communication industry for equipment cabling and antenna interfaces. |
 | SMA The SMA (Subminiature A) connector was designed by Bendix Scintilla Corporation and Omni-Spectra Corporation as the OSM connector, and is one of the most commonly used RF / microwave connectors. It is intended for use on semi-rigid cables and in components that are connected infrequently. It takes the cable dielectric directly to the interface without air gaps. A standard SMA connector is designed for interconnects to 12.4 GHz. Fortunately, a good SMA is useable to 18 GHz in most cables, and if well constructed with greater loss and lower return loss to 24 GHz. |
 | Type 43.
These coax connectors are used widely in the telecommunications industry. Typical uses are for 2Mb/s & 34Mb/s circuits. They use a push-pull latch action and can be grouped in high density patch panels. |
 | "D" Series, 9 pin.
Widely used in computing and electronic equipment. So called because of the "D" shape of the housing. Special versions can include high current pins and coax pins. For example, 13W3 is a 25 pin shell size fitted with 10 normal pins and 3 coax connectors. They are used on high-end workstation class computers such as SGI and Sun. Wikipedia |
 | SC (Stick & Click) | Push-Pull Latch, Multimode and single mode fibre. |
 | ST (Stick & Twist) | Bayonet Latch, Multimode and single mode fibre. |
 | FC (Fibre Connector?) | Threaded Latch, only Single Mode fibre. |
 | FDDI - Fibre Distributed Data Interface | Usually Multimode Fibre. |
