Specialty Optical Fibers for Geophysical
Specialty fibers create a fuller picture of the geophysical environment by enabling optic sensors that measure temperature, strain, pressure, acoustics, depth, and other parameters. The environments these fibers experience can be physically destructive to standard optical fibers. Not only have we surmounted the harsh conditions with our unique coating system, but we are also now pushing the limits of high-temperature performance with pure silica cores. Our GeoFibers™ are currently being used in DTS (Distributed Temperature Sensing) applications around the globe, and feedback from these working applications further contributes to our knowledge base.

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.
AquaLink
AquaLink coating is our newest defense against water in outdoor cabling applications.
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.
