Network Converters provide feasibility in network configurations. For example media converters allow using different standard cables within the same networks, or serial converters convert between various serial standards.

Media Converter

A network media converter is network equipment that interconnects the cables of different standards within an existing network. Media converter allows communication using different types of cables associated with different standard devices within the same network. For example to connect gigabit Ethernet based network to 10 Base-T Ethernet based network, a media converter is used. Cables supporting different standards are attached to the media converter. The converter receives the signal from one cable standard and converts it according to the standard to be sent.

Media Converter Specifications

There are three major concerns associated with Media converters. They are converter type, network type, and connector type.

Media Converter Types

Different types of media converters re available and can be selected according to the requirements. Media converts in multimode serves for more than two cable standards conversion. Media converter as standalone device usually converts between two media types only. To serve in multimode, media converters are available as rack mounted and chassis based modules. Both the types standalone and module are available in full duplex and half duplex modes. The devices may also contain uplink switches that eliminate the use of cross-pinned cables for workstation or hub connection. Moreover media converters are also available as integrated circuit and printed circuit boards.

Network Types for Media Converters

Before selecting a media converter it is necessary to analyze that for what type of network it is required, and especially what are the equipment and cable specifications. Ethernet protocol based networks are most commonly used local area networks (LANs). Media converters also support other common networks including ATM (asynchronous transfer mode), Token Ring, optical carrier, and single and multimode fiber. Media converters also offer serial communication support for RS-232, RS-422, and RS-485 serial interfaces.

Media Converter Connectors

Another issue that is essential to consider is port connectors available in the media converters. AUI (attachment unit interface) connectors support Ethernet network and stations. DB-9 connectors are commonly used for serial ports and are available in media converters. In other commonly used there are bayonet Neil-Concelman (BNC) connectors, RJ-45 Connectors, subscription channel (SC) connectors, ST (straight tip) connectors, MT-RJ connectors, and medium Interface Connector (MIC). MICs are used in FDDI (fiber distributed data interface) networks.

Serial data Converters

Serial communication is attained using various serial standards such as RS232, USB, and RS422. In a network all the standards can be used according to requirements but with serial data converters. A serial data converter allows connecting two different serial communication standards with each other. A serial converter interconnects RS422 to RS232 or RS232 to USB.

Specifications

Three important specification associated with serial converters are agency approvals, indicators, and environmental parameters. Common agencies that approve these converters include FCC, TUV Rheinland, CSA Mark, C-UL US Listing Mark, and UL Listing Mark. Indicators are used to specify certain functions such as data is transmitted, error detection, power on or off, and other such functions. Temperature and humidity are environmental parameters that may affect the converter.
