When looking for a high quality fiber with superior transmission and a numerical aperture (N.A.) of 0.22 for efficient light coupling, the Superguide™ SFS is the fiber of choice. The Superguide™ fiber is drawn from preforms manufactured by the Plasma Outside Deposition (POD) process. Rods of extremely pure synthetic fused silica are coated with fluorine doped silica layers to obtain preforms with step-like refractive index profiles. Plasma torches prepare the reaction compounds from SiCl4, O2, and a fluorine containing gas. Strong thermal gradients combined with the temperature plasma lead to chemical deposition conditions, which allow very high fluorine concentrations to be incorporated in the fused silica network. Refractive index differences of 0.27 corresponding to numerical apertures in excess of 0.28 have been realized with undoped core rods.

Silica optical fibers, despite their high strength, require coatings to protect and maintain their strength during installation and operation when high temperatures, abrasion, bending, and other stresses can cause fiber fatigue. OFS offers both single-mode and multimode optical fibers with protective coating layers applied directly to the glass during the fiber draw process.

When looking for a high quality fiber with superior transmission and a numerical aperture (N.A.) of 0.22 for efficient light coupling, the Anhydroguide™ AFS is the fiber of choice. The Anhydroguide™ fiber is drawn from
preforms manufactured by the Plasma Outside Deposition (POD) process. Rods of extremely pure synthetic fused silica are coated with fluorine doped silica layers to obtain preforms with step-like refractive index profiles. Plasma
torches prepare the reaction compounds from SiCl4, O2, and a fluorine containing gas. Strong thermal gradients combined with the temperature plasma lead to chemical deposition conditions, which allow very high fluorine
concentrations to be incorporated in the fused silica network. Refractive index differences of 0.27 corresponding to numerical apertures in excess of 0.28 have been realized with undoped core rods.

With numerical aperature (N.A.) of 0.39 and a hard polymer cladding that allows a high core-to-clad ratio, the Anhydroguide™ APCH is the low cost fiber of choice. The pure fused silica (SiO2) used in the core of Anhydroguide™ fiber is made by reacting silicon tetrachloride (SiCl4) with oxygen (O2) using a plasma arc rather than an oxy-hydrogen flame. This ensures that the residual hydroxyl concentration (OH) will be low in the core material resulting in superior infrared transmission as compared with flame prepared silica that is used in the
companion product, Superguide™, which has superior ultraviolet (UV) transmission.

Long life, deep UV transmission is made possible with Fiberguide¡¯s solarization resistant optical fibers, wherein the fiber core and clad are hydrogen doped at very high temperatures as the fiber exits the draw furnace and then hermetically sealed with an aluminum buffer/jacket during the fiber draw process. This break-through, patented in-line process allow the use of fiber with a wide variety of UV laser sources, making Solarguide¢â 193 the fiber best suited for deep UV (¡Â 300nm) applications. Irradiation of standard silica fibers with UV photons below 260nm generates defects in the standard silica
structure, so-called ¡°solarization¡±. The solarization is the reason for the significant decrease in standard fiber transmission in UV wavelengths over time making fiber eventually useless in that application. When present in the silica core, hydrogen combines with the defects generated and neutralizes them, preventing the UV photons from being absorbed and thereby lost. Although the effect of hydrogen in lowering the fiber solarization rates in silica is widely known, Solarguide¢â 193 is the only fiber in the industry that has its own
hydrogen supply which has been sealed in with a hermetic shroud (aluminum buffer) around the fiber, thereby making it available for keeping the fiber solarization resistant for significantly longer periods.

Sensors with fibre optics are used for optoelectronic sensing applications where mounting space is limited or where high operating temperatures do not permit the use of conventional sensors. Due to their small design and optical properties they do not only detect the presence of objects but also quality-related details, e.g. thread pitches of screws.
Transmitter and receiver of the fibre optic sensors are integrated into one housing. The fibre optic is connected to the switching amplifier using a special adapter, and so there is almost no loss. Fibre optics can be used as through-beam sensors or diffuse reflection sensors.
Fibre optics consist of flexible glass fibre bundles protected against external influence by a sheath.

Polymer cladded fiber (PCF) has been on the market for many years, standing out by being very robust and easy to assemble. Compared with thick-core glass fibers, they are not only more robust but also considerably cheaper.
PCF consists of a silica core with polymer cladding. What is especially important here is good adhesion of the cladding material to the glass core, which does not go without saying because of the different expansion coefficients especially at high temperatures. This is where the many products on the market differ most. It is also why there are a vast number of different abbreviations such as PCS, HCS, HPCF, etc.
Low attenuation makes it possible to cover distances up to 500 metres with systems designed for POF (about 660nm), and up to 4 kilometres with 850 nm systems.

Polymer optical fiber (POF) has been on the market for many years. Both the fiber core and the cladding are made of polymer. Key advantages of polymer optical fibers are high flexibility (high alternate bending resistance with smaller bending radii) as well as more economical connecting and transmission technology than in the case of glass. Moreover, this type of fiber also has all the major benefits of a fiber optical cable connection: EMC security, clear galvanic separation, no crosstalk, low weight, etc.
POF can meanwhile be used to connect over distances up to 70 metres, which is normally sufficient for both industrial environments and smaller office as well as home networks. It is even possible to cover distances up to 150 metres by selecting suitable active components.

While single mode silica/silica fibers are available from a number of suppliers with standard polymer coatings, Fiberguide is unique in offering these fibers with high performance buffers/coatings of aluminum, gold or polyimide. A single mode fiber has a sufficiently small core diameter that it can only transmit a single transverse optical mode. Typical core diameters are in the range of several microns up to around 10 microns depending on the wavelength being transmitted. Conventional single mode fibers covered in this data sheet have circularly symmetric cores. As such, they can actually transmit two orthogonally polarized modes. Normally, this aspect is ignored because such orthogonal modes travel at nearly the same velocity and they can be treated as one. However, in very high data rate systems and other critical applications it is important to preserve the polarization state that is launched into the fiber. Such cases require the use of polarization preserving single mode fibers that are discussed in the accompanying data sheet.
