CARBON COATING CAPABILITY

Carbon ... A primary fiber coating of carbon extends fiber lifetime dramatically. A very thin layer of amorphous carbon is applied to a thickness of 300 to 400Å in a reactive process during draw. This layer hermetically seals the fiber surface and increases the typical fatigue resistance (n-value) of the fiber from 20 to greater than 100. Carbon can be applied under acrylate, silicone or polyimide coatings, depending on the temperature requirements of your application.

In general, optical fibers are recommended to operate at 20% of the prooftest level of the fiber (100kpsi or 200kpsi). Hermetic carbon fibers can withstand a higher application stress (tensile or bending) than a non-hermetic fiber. They can operate at 80% of the prooftest level with a standard lifetime, or at a lower stress level for a much extended lifetime. Carbon's value is two-fold: to provide a hermetic seal to the glass surface at all temperatures, and to protect against hydrogen ingression up to 120°C.

Other coatings are also available. For other options, see our High-Temperature Coatings and Cabling Capabilities Brochure.

Avioptics
Avioptics harsh environment cable optimizes high-performance aircraft and military vehicle applications. The cable design is based on 200 µm fibers and adds coating and strength members especially for the corrosive environments encountered on aircraft, including jet fuel, oil. Solvents, and hydrolytic liquids.
FlightGuide
The FlightGuide family of aerospace fibers and cables offers high temperature and strength in graded-index fiber-based constructions. Multiple coating and cabling layers specialize the cables for military and aerospace use. Some FlightGuide fibers are available sold separately.
HCS
Hard Clad Silica (HCS) was invented by OFS scientists and now serves as the industry standard cladding material for optical glass fibers. HCS cladding imparts unusual strength to fiber and makes it easy to crimp and cleave connectors directly to the fiber using a hand tool in the field instead of more complex epoxy/polish methods.
OASiX
Optical Amplifier Simulation Software from OFS, OASiX is packaged with erbium-doped fibers sold for use in EDFAs. This software and graphical interface allows the designer to plug in modeling parameters shipped with the fiber and begin on-screen simulations. This reduces design time by predicting the performance of EDFA systems including optical components such as filters, isolators, and reflectors.
ST
This connector type features a bayonet-style nut and is commonly used in telecommunications applications.
TruePhase
TruePhase is the name to remember for all of OFS’s non-doped polarization maintaining fibers. These are single mode fibers optimized for different wavelengths and cladding size requirements.
V-System
This easy-to-use connectorization system simply plugs in with a reassuring click. It is available for simplex cables, or with a duplex latch housing for connectorizing zipcord. Connectorizing HCS coated fibers with V-System connectors takes less than 2 minutes per end when using the compatible OFS crimp and cleave kit.
ClearLite
One of the most complete, diverse lines of single-mode optical fiber you can find, ClearLite encompasses several families of photonic fibers, each optimized for different applications: 980, 1310 & 1550, Micro, Specialty Coated, Short Wavelength, and Polarization-Maintaining.
GyroSil
Designed specifically for gyroscopes and similar navigational instrumentation, GyroSil singlemode fiber has a small NA of 0.17 and reduced 80 µm cladding diameter to accommodate the tight bend radii and coiling designs inherent in gyroscopic and sensor applications.
PYROCOAT
PYROCOAT polyimide is our premier fiber coating for high-temperature applications. In recent years, we have further refined the polyimide properties to create new versions of PYROCOAT optimized for steam or chemical resistance. When applied over a hermetic carbon layer, it provides the best protection in the industry against the harshest environments.
UltraSil
Known in the medical industry for years for its ultra low water peak useful for high-power delivery, our UltraSil fibers are made from unique preforms that deliver both low OH and one of the highest NAs achievable with a silica cladding. These fibers are also finding new application in sensing when further coated with high-temperature polyimide.
