Fibre Channel Connectors Information
Fibre Channel connectors are high-speed devices used in Fibre Channel systems. They are designed for telecommunications, video, networking, and storage area network (SAN) applications. Fibre Channel is a high-speed, serial-data transfer architecture that uses links of copper or optical cable to achieve speeds measured in the gigabit (GB) range. The most popular Fibre Channel standard is Arbitrated Loop (FC-AL), a network topology which can support full-duplex data transfer rates of 100 MBps. Specifications for Fibre Channel connectors include gender, voltage rating, current rating, number of contacts, and operating temperature. Male Fibre Channel connectors or plugs mate with female Fibre Channel connectors or jacks. Voltage rating is the maximum operating voltage. Current rating is the maximum, recommended, continuous flow of electrical current. If an approval organization defines a maximum voltage or maximum current that differs from the supplier’s maximums, check with the supplier for specific usage details. The number of contacts in a Fibre Channel connector is the number of number of conductive elements that mate with a corresponding element to provide an electrical path.
There are many different types of Fibre Channel connectors. D-Subminiature (D-sub) connectors have a mating face that is shaped like the letter "D". This shape provides polarization since D-shaped male and female connectors fit together in only one way. Gigabit interface converters (GBIC) are transceivers that convert between serial-electrical and serial-optical signals for high-speed networking. They are used with both Fibre Channel and Gigabit Ethernet networks. Media interface adapters (MIA) are Fibre Channel connectors that convert DB9 copper signals into optical signals, and vice versa. High-speed serial data connection (HSSDC) cable connectors are designed to facilitate gigabit-per-second (Gbit/sec) data transmissions. HSSDC2 connectors are an improved version of the original HSSDC cable connector and are designed to facilitate Gbit/sec data transmissions. Triax connectors are used with triaxial cables where maximum RF shielding and minimum noise radiation is required. Twinax connectors are used with twinaxial cables for balanced low level and high sensitivity circuits. Twinax connectors feature polarized key and keyway construction as well as threaded coupling.
Fibre Channel connectors differ in terms of approvals, certifications, and applications. Products that meet U.S. government specifications conform to standards such as MIL-DTL-38999, MIL-DTL-861659, and MIL-DTL 83527. Standards from Aeronautical Radio, Inc. (ARINC) include ARINC 404 and ARINC 600/64 (Ethernet for the Sky). Typically, ARINC connectors are used in aerospace and military applications. Storage area networking (SAN) applications uses Fibre Channel connectors as part of high-speed networks that make all storage devices available to all servers on a local area network (LAN) or wide area network (WAN).

Coaxial connectors are composed of an insulated central conducting wire wrapped in another cylindrical conductor (the shield). The cable is usually wrapped in another insulating layer and an outer protective layer. Coaxial cables and connectors have the capacity to carry vast quantities of information. They are typically used in high-speed data and CATV applications.
Card edge connectors are edge-on connectors designed for single-sided or double-sided printed circuit boards (PCBs).
Gender changers are devices that change the end of a cable into another type, allowing two cable assemblies with the same or different genders to mate.
