These products connect equipment containing RS 232 serialports with other equipment containing serial portswith different communication protocols.The ILPH D-Sub products:

- extend transmission distance of the RS 232 serial portbeyond 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 theproducts have very good EMC performance.

Protection against overvoltage and its galvanicisolation make these products safe in very harshindustrial environments.

Host powered by RS 232 signals

An external power supply is not required to operatethe ILPH D-Sub products. The RS 232 signals powerthe interface modules, making them easy andconvenient to use.

Easy configuration and handling

Configuration is performed with Dip-switches. Theconnection cable is secured with cable holders,which also supply shielding continuity.

This new self-powered product range allows a directconnection from an RS 232 serial port to an RS 422-485, 20 mA current loop or plastic fiber optic serialinterface.

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 115.2 kbits/s

How fiber optics work ?

The basic principle of wave propagation into a fiber optic is based on the total reflection effect. This property is very useful andthe 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 otherparameters 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 deformationand 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 twogroups:

• Step index fibers

In these fibers, the light beams are totally reflected at the interface ofthe core and the fiber housing, but as some waves are more oftenreflected then others, the output pulse has a bigger deformation. Sucha fiber is not really well suited for industrial application or only forshort distances. This type of fiber also exists in plastic material with adiameter of 980/100 µm.

• Gradient fibers

In the gradient fiber, the index of refraction decreases slightly and continuouslyfrom the fiber axial core to the fiber housing. The light beamsare then no more diffused in "zig-zag" fashion but in wave form. The bigadvantage of such a fiber is faster propagation of the light into thethe fiber and then when the index is appropriate, the output pulseis not modified. As the power attenuation is very small,these fibers are very well suited for long distances up to 3 km. Thecommonly used fibers have a diameter of 50/125 µm and 62.5/125 µm.
