This type of fiber can operate even at +125°C. New Standard Form Factors. Since the bandwidth-distance product required is smaller, one can use large core fibers such as the plastic optical fiber (POF) and polymer cladded silica (PCS) fiber. Since the beginning of this millennium new applications have emerged in the fields of automotive, industrial control, consumer electronics, home networking and optical backplane interconnects.

If you look closely at a single optical fiber, you will see that it has the following parts: Advertisement . International Journal of Scientific & Engineering Research, Volume 4, Issue 7, July-2013 205In several European vehicles, the provision of optical networks has already started in luxury grade models. Far too many people to mention individually have assisted in so many ways. Many European car manufacturers have already adopted the MOST system. In addition, other companies and organizations are creating network systems that utilize POF, such as Byteflight from BMW-a protocol that supports the increasing number of sensors and actuators within cars that improve vehicle safety. This is the first time that POF has been used for such a “mission-critical” application. [6]The most important use for POF in automobiles is for theIn addition to protecting vehicle occupants, POF is being used for pedestrian-protection systems. Polymer cladded silica (PCS) fiber is under consideration to overcome the current operating temperature limitations. To hold them in place I applied some glue to the fiber and the side of the front seats and then used a twist tie to hold them in place until the glue dried. While many of these sensors are nonoptical, the evanescent field of an optical fiber can also be exploited in this application. Conventional electronics packaging technologies such as automatic pick-and-place and transfer molding can be employed in mass production of optical transceivers.

Polymer cladded silica (PCS) fiber is under consideration to overcome the current operating temperature limitations. These fibers are called " side emitting" fiber optics. The MOST and IDB1394 standards are an example for automotive infotainment systems. In ray optics, this phenomenon is known as the “GoosHanchen-Shift,” in which the reentry of the ray into the core region is shifted along the geometrical core-cladding interface. The spatial resolution is achieved by incorporating several fiber strands in parallel and using numerical signal analysis of the treated zones. In every sense, none of this work would have been possible without him. The sensor can distinguish between a human and an inanimate object, triggering the hood to lift and softening the impact if a human is struck. The spatial resolution is achieved by incorporating several fiber strands in parallel and using numerical signal analysis of the treated zones. Plastic optical fiber (POF) has been used in automotive networking systems since 1998 after successful introduction by Mercedes Benz, spurring the introduction of the Media Oriented Systems Transport (MOST) standard—a reliable and robust network protocol for an … Bending the fiber in one direction leads to a better transmission whereas bending in the other direction leads to a lower transmission, compared to the straight position. This shift can be detected with very high sensitivity, allowing the motion of a window to be stopped if an object is in its path. Based on the positive experience gained with POF systems for vehicle entertainment and safety systems, companies are now confident that POF sensors will meet the most challenging automotive requirements and comfortably move into consumer applications. This is an advantage in particular for video type applications. Step 2: End Emitting Fibers. Since the bandwidth-distance product required is smaller, one can use large core fibers such as the plastic optical fiber (POF) and polymer cladded silica (PCS) fiber.Fiber Optic Sensors, Pedestrian-Protection Systems, Polymer Optical Fibers, Seat Occupancy Detection, received her B.Tech. [6]International Journal of Scientific & Engineering Research, Volume 4, Issue 7, July-2013 209From this study on use of optical fibers in automobiles we conclude that Photonic technologies are superior to electronic solutions in terms of data rates, bandwidth, reliability, and robustness. Increasing demands regarding temperature performance, transmission losses, and bandwidth have pushed the current limits of the POF fiber, and the automotive industry is now moving towards an optical domain.of the cost of their pure silica counterparts .And it's not just navigation and entertainment functions that can exploit POF.Fiber optic transceivers (FOT) based on lead frame and plastic molding technologies for large core plastic optical fiber (POF) and polymer clad silica (PCS) fiber systems. This shift can be detected with very high sensitivity, allowing the motion of a window to be stopped if an object is in its path. Currently plastic optical fiber (POF) and 650nm LEDs are used in the fiber optics systems . The various infotainment devices (such as for example: radio “A,” CD player “B,” navigation system “C”) are connected in a fiber optic ring. Though POF suppliers are scurrying to meet these requirements, plastic-clad silica fibers and multimode glass fiber bundles are also being considered.An area of concern when using POF in automotive applications is the availability of light sources that deliver the needed modulation speeds. The laser transmitter emits in the near infrared at 850nm. The normal operating speed is 50Mb/s for applications in the automotive infotainment system.

If the seat is empty in the event of a collision, for example, the air bag will not deploy, saving the expense of repair and replacement. Therefore the current fiber systems are limited to the passenger compartment. The major application areas of optical sensors are driver assistance systems and traffic monitoring systems. This technology is therefore widely used in internet cables.
