OFS ClearLite™ Specialty Coated Fiber Poly 1310-11

Designed for performance in exceptional environments, these fibers operate at the standard transmission wavelengths of 1310 and 1550 nm. Both of these fibers are coated with PYROCOAT™ polyimide coating that allows wide temperature performance of -65 to +300°C. Polyimide is a thin coating and is applied to a thickness of only 15 μm on a 125 μm cladding. This gives a coated fiber outer diameter (OD) of 155 μm, as opposed to a standard 250 μm OD for dual acrylate coatings. Both fibers feature a matched clad design with 0.11 NA and large MFDs of 9.3/10.5 μm at the opening wavelengths. Carbon/Poly 1310-11 also has a base coating of carbon beneath the PYROCOAT coating to provide hermetic protection to the fiber. Most optical fiber breaks originate in microscopic cracks on the fiber surface that propagate over time due to the destructive effects of water vapor. These breaks can be significantly reduced by the presence of the carbon layer, which provides a hermetic seal on the fiber. The carbon layer is only a few hundred Angstroms thick, but greatly enhances the N-value, or lifetime, of the fiber.
