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.

Multimode fiber is characterized by its ability to allow numerous modes of light to be transmitted simultaneously. With a large core diameter multimode fiber is coupled easier then single-mode fiber resulting in its wide use in variety of industry, scientific and medical applications.

When looking for a low cost fiber with a high numerical aperture (N.A.) for more efficient light coupling, the Anhydroguide™ PCS is the fiber of choice. With an N.A. of 0.37 and a plastic cladding that allows a high core-to-clad ratio, satisfies those requirements and more. The pure fused silica (SiO2) used in the core of the 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.

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.

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.

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.

Fibercore Limited HiBi is a singlemode, polarisation-preserving optical fibre designed for high-performance interferometric and polarimetric sensors, integrated optics and coherent communications.
The characteristic 'Bow-Tie' stress-applying parts, or 'SAPs' act like opposing wedges to generate the optimum stress distribution within the fibre. This unique and patented design gives you the very best in both performance and handling - maximum birefringence, with minimum stress-breakout when cleaved, connectorised or polished.

OFS ClearLite™ TruePhase™ Polarization-Maintaining fibers are available in a full range of wavelengths. They use industry-standard, stress-applying parts (SAPs) to create two axes in the core, each of which guides light at a different velocity. Crosstalk between the two axes (fast and slow) is suppressed so that polarized light launched into either of the axes will remain polarized as it is guided. Our dual, circular design allows use of standard splice recipes from all major splice equipment manufacturers. When spliced correctly, TruePhase fibers exhibit low loss and high extinction ratios.

Optical fiber manufactured to retain the fidelity of each light pulse, allowing for greater distance of transmission. Single mode fiber is characterized by a low attenuation making it ideal for telecommunication as well as applications requiring a high amount of information to be transferred per unit of time.

When your work environment calls for something more than the standard 250 µm primary coating, Fibercore Limited optical fibers are also available as ruggedised cables. The standard LT3 design has a 3.0 mm diameter PVC outer jacket, surrounding aramid yarn strength members. The fiber itself is contained within the inner, polypropylene loose-tube of 1.8 mm in diameter.
LT3 provides essential protection for valuable fibers in all indoor and light outdoor applications and is fully compatible with the Fibercore Limited range of polarisation maintaining connectors.

Fibercore Limited's Singlemode Optical Fibers have been proven to perform in a wide range of challenging applications including laser-doppler velocimeters, holography probes, EDFA pump pigtails, acoustic sensors and de-polarised FOGs.
The latest additions to the range responds to specific demands from the Telecommunications and Sensor Industries. SM980(4.5/80) and SM1250(9/80) address the need for reduced diameter fibers for the manufacture of small form-factor components for telecoms - SM1250(5.4/80) and SM1500(5.3/80) further increase the options available for hydrophones and de-polarised FOG. Just like all of our SM products, these new fibers are optimised for the fabrication of low-loss, fused-taper components and reliability tested to Telcordia™ standards.

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.
