Choosing a fiber type and its specifications is critical to the overall success of an application for specialty optical fiber. Each of the 7 categories, there is a selection chart to help narrow down choices by common specifications. Detailed specification sheets follow. Assistance at any point in the selection process is readily available by contacting us directly, click here.

Clearlite Single-Mode Photonic Fibers SELECTION CHART

Product	Description
980 Photonic Fibers CL 980 14 CL 980 16 and 20	Whether used in the typical 980 nm applications such as laser diode pigtails or in pump signal WDM coupler, two specifications are critical to selection: Numberical Aperture (NA) and Mode Field Diameter (MFD). A larger MFD (with correspondingly lower NA) allows more light to be coupled into the fiber for efficient pigtails. Higher NA gives premium coupler performance and will perform at dual wavelengths of 980 and 1550 nm.
1310 and 1550 Photonic Fibers CL 1310 16 and 21 CL 1550 12 and 17	These fibers are designed for use at the standard transmission wavelengths of 1310 and 150 nm. If the goal is to mode match with standard transmission fibers, choose a lower NA. This should be balanced with required bend performance, which improves with a higher NA.
Micro Photonic Fibers CL Micro 820 16 CL Micro 980 17 CL Micro 1310 11, 16S, and 16D CL Micro 1550 17 GyroSil, and 21	Small than standard 125 µm clad fibers, micro fibers have an 80 µm cladding for miniature components and integrated packages. Reduced diameter means improved bend performance and smaller coils for sensors. Select by wavelength as you would for standard diameter fibers.
GeoFibers Geo 1310 11 and 16 Geo50 SA	Highly specialized for downhole deployment, well-to-well data transmission, and Distributed Temperature Sensing (DTS), these fibers feature a dual-coating system: a hermetic carbon layer followed by a PYROCOAT high-temperature polyimide for operation up to 300°C.
Specialty Coated Photonic Fibers CL Carbon/Poly 1310 11 and CL Poly 1310 11 CL Carbon Acrylate 1310 16 CL Poly 1310 21 and 1550 17	Certain environments require specialized coatings to protect the fiber and ensure reliable funcionality under high temperatures, moisture, and other extremes. PYROCOAT polyimide protects in high temperatures. Carbon gives hermetic properties in high humidity environments and is resistant to most chemicals.
Short Wavelength Photonic Fibers CL 630 11, 780 11, and 820 16	Sensors and communication systems transmitting at 630 to 820 nm wavelengths-including lasers and LED sources-use these 125 µm core/245 µm dual-acrylate coated fibers.

TruePhase polarization-maintaining fibers are available in a full range of wavelengths. TruePhase fibers utilize industry-standard, stress-applying parts (SAPs) to create two axes in the core, each of which guides light at a different velocity. Crosstalk between those axes is suppressed so that polarized light launched into either axis will remain polarized as it is guided. Detailed specification sheets follow.

Most multimode fibers from OFS are of step-index construction and are grouped together by their Numerical Apertures, with additional categories for Low OH, High OH, and Launch application constructions. Included in this section are products using our well-known hermetic carbon-coating expertise, as well as HCS and PYROCOAT brand technologies. Many are compatible with our easy-to-use crimp and cleave termination system. For quick comparison of primary specifications among our step-index offerings, see our Specialty MM Step-Index Fibers SELECTION GUIDE.
