Network Device Interface Type

11/16/15  |  Technical Article

BNC Interface

BNC interface refers to the coaxial cable interface, which is used 75 ohm coaxial cable, providing income (RX), send (TX) two channels, which is used to connect unbalanced signals.

Optical interface

Optical interface is connected to the fiber optic cable physical interface. Usually SC, ST, LC, FC and other types. For 10Base-F connections, usually ST type connectors, and the other end connected to the optical fiber FC step bobbin. FC (Ferrule Connector), to strengthen its external way is to use a metal sleeve, fastening means for the turnbuckle. ST interface is typically used for 10Base-F, SC interfaces typically used to 100Base-FX and GBIC, LC typically used for SFP.

RJ-45 interface

RJ-45 interface is the most commonly used Ethernet interfaces, RJ-45 refers to the IEC (60) 603-7 standardization, the use of eight positions by the international standard definition connector (8-pin) modular jack or plug.

RS-232 Interface

RS-232-C interface (also known as EIA RS-232-C) is the most commonly used as a serial communication interface. It is a standard for serial communications in 1970 by the American Electronics Industry Association (EIA) Joint Bell System, a modem manufacturers and computer terminals manufacturers jointly developed. Its full name is "serial binary data exchange interface between technical standards for data terminal equipment (DTE) and Data Communications Equipment (DCE)". The standard specifies the use of a 25-pin DB25 connector, to be provided for each pin connector signal content, but also to provide for the level of various signals.

RJ-11 interface

RJ-11 interface is what we usually call the telephone line interface. RJ-11 is a generic name for Western Electric developed connectors. Its shape is defined as a 6-pin connector devices. Formerly known as WExW, where x means "active", the contact wire or pin. For example, WE6W have all six contacts, numbered 1 through 6, WE4W interface using only 4-pin, the outermost two contacts (1 and 6) do not, WE2W use only the middle two pins (ie, using the telephone line interface).
