AFL Exhibiting at OTC in Houston; Showcasing Industrialized Downhole Cables, Specialty Optical Fiber

Spartanburg, SC – AFL, an industry-leading manufacturer of fiber optic cable, equipment, and accessories, is exhibiting at the Offshore Technology Conference (OTC) in Houston, Texas. Visit AFL in booth #2253 to learn more about hybrid electro-optical and high-temperature downhole cables plus low-loss, metal-coated optical fibers rated for temperatures up to 500⁰C.
AFL recently industrialized its 4mm Hybrid Electro-Optical Downhole Cable to achieve continuous lengths up to 25,000 feet while delivering 12 fiber positions and voltages up to 1000V on an 18 AWG conductor. The 4mm armor has a nominal wall thickness of .028”, providing substantial hydrostatic pressure resistance, tensile strength and column strength. This hybrid downhole cable has been tested at temperatures up to 175°C. 

AFL also further industrialized its High-Temperature Downhole Cable design to reliably achieve longer continuous lengths. Constructed with a three-layer, all-metal design, the high-temperature downhole cable provides both an inner and outer layer of stainless-steel tubing to protect against temperatures and pressures associated with well environments, and a middle layer of aluminum to inhibit hydrogen permeability and extend the life of the optical fiber. By using an all-metal design, the concern of polymers at elevated temperatures is eliminated and a more stable performance is achieved. As the use of engineered fibers, which may not have a carbon layer or hydrogen resistant glass chemistry, proliferates, AFL’s updated high temperature downhole cable design provides a unique solution to hydrogen resistance that might not otherwise be available for these fibers.

The 500⁰C VHT500 single-mode and VHT5000 multimode fibers feature advanced glass chemistries for improved performance in hydrogen-rich environments and excellent optical performance in permanent, long-term exposure to temperatures up to 500⁰C. Maximum attenuation of the VHT Series is 5dB/km for all typical operating wavelengths.

Discover all these solutions and more with AFL in booth #2253 at OTC, August 16-19 at NRG Park in Houston, Texas. To learn more about AFL, its products and services, visit
