Glass optical fibers are constructed of tiny strands of glass that are bundled together inside an application-specific sheathing like stainless steel for durability and high temperatures. They are attached to certain photoelectric sensors and guide light from the sensing head to the target. Basically, glass fiber cable enables you to use a photoelectric sensor in areas where you wouldn’t normally be able to use them. The sensors are available with a wide range of housings, mounting styles, and features for your specific application.
Glass optical fibers have an impressive temperature range, as low as -40 °F and up to +900 °F. That’s because the cables have no electrical components.They merely act as a conduit, or light guide between the target and the sensor. So, they can be used in high-temperature applications like furnaces, ovens, and condensers in large engines, and they can also be used in extremely low temperature areas such as cold storage warehouses.
And because glass cores are efficient at transmitting light, allowing for significantly higher transfer speeds, they can be used at long sensing distances. Glass fiber optic cables are extremely versatile and robust and are available in a mix of configurations, end fittings, and adapter types. Even more, glass fiber optic cables are optimized for small spaces and small targets. They can be used with both visible red and infrared light and are compatible with a long list of fiber heads.
Plastic Optical Fiber (POF) is an optical fiber which is made out of plastic rather than traditional glass. With very small diameter, the POF cable is easy to run along skirting boards, under carpets and around tight corners. It offers additional durability for uses in data communications, as well as decoration, illumination and industrial application. The plastic optical fiber as the ideal short-range communication network transmission medium, has an important position in military communication network and multimedia equipment in the data transmission.
POF fiber provides numerous advantages over glass optical fiber without compromising the performance of products and services. To be extremely reliable and rugerizada, POF has been adopted in many different markets. With data rates up to 1 Gbps and guarantee high quality service, POF is the most robust technology for Ethernet networks to 100 Mbps Optical Plastic fiber optic is also particularly suitable for developing new applications with high bandwidth, including IPTV and Triple Play services.
The light passes through the central portion of the plastic optical fiber diameter of about 1mm, about 100 times larger than the glass fiber, and the connection between the fiber connection and personal computer terminal apparatus is very easy.
Plastic optical fiber, although the light-transmitting differential, light loss is large, the initial ships of 300 dB/km, the transmission optical narrow band (limited to the visible region), difficult to adapt to the needs of the multimedia communication network, but it has a series of advantages, including light and soft, flexural, impact strength, cheap, anti-radiation, easy to process and can be made (1 to 3 mm in diameter, in order to increase the light-angle, expand the scope of), so favored. In addition, plastic optical fiber installation costs low, very simple installation can align the connector plug, this plug can be used existing technology to produce.
