1 92325_EL Serial Data Converters D-Sub Serial Data Converters D-Sub RS 232 / RS D-Sub RS 232 / BdC D-Sub RS 232 / FO-P This new self-powered product range allows a direct connection from an RS 232 serial port to an RS , 20 ma current loop or plastic fiber optic serial interface. The three D-Sub products offer users: Small rugged metal D-Sub housing Host powered by the RS 232 signals High protection against overvoltages Easy configuration and handling Galvanic isolation (RS 232 / BdC and FO -P) Baud rate up to kbits/s These products connect equipment containing RS 232 serial ports with other equipment containing serial ports with different communication protocols. The D-Sub products: - extend transmission distance of the RS 232 serial port beyond 15 m (50 ft) - can be used in "noisy" environments, - perform multidropping (networking) for RS 485 and current loop - act as active or passive current loop, - isolate the two interface systems - protect against overvoltages with fiber optic (e.g. lightning strikes) Good EMC performance The small, rugged metal enclosure ensures that the products have very good EMC performance. against overvoltage and its galvanic isolation make these products safe in very harsh industrial environments. Host powered by RS 232 signals An external power supply is not required to operate the D-Sub products. The RS 232 signals power the interface modules, making them easy and convenient to use. Easy configuration and handling Configuration is performed with Dip-switches. The connection cable is secured with cable holders, which also supply shielding continuity.

This property is very useful and the light is permanently reflected between the fiber core and fiber housing and so guided along the fiber. Various types of fiber optics: In addition to the material used for the fiber optic itself (plastic or glass), the fabrication mode is also very important to assure a qualify fiber. Two other parameters must also be taken into account: Unimode or monomode fiber Multimode fiber A monomode fiber has a very small diameter, allowing only the fundamental wave to come through. The advantage of this fiber is that pulse deformation and power loss are very low, but the high price is a drawback. Multimode fibers allow the propagation of various waves (fundamental and others) into the fiber core (relatively large diameter). They are divided into two groups: Step index fibers In these fibers, the light beams are totally reflected at the interface of the core and the fiber housing, but as some waves are more often reflected then others, the output pulse has a bigger deformation. Such a fiber is not really well suited for industrial application or only for short distances. This type of fiber also exists in plastic material with a diameter of 980/100 µm. Gradient fibers In the gradient fiber, the index of refraction decreases slightly and continuously from the fiber axial core to the fiber housing. The light beams are then no more diffused in "zig-zag" fashion but in wave form. The big advantage of such a fiber is faster propagation of the light into the the fiber and then when the index is appropriate, the output pulse is not modified. As the power attenuation is very small, these fibers are very well suited for long distances up to 3 km. The commonly used fibers have a diameter of 50/125 µm and 62.5/125 µm. 828
