1 SPECIALTY FIBER OPTIC CABLE Specialty Fiber Optic Cable © 2004, AFL, all rights reserved. PP-1-00079, Revision 4, 2.4.2021 Specifications are subject to change without notice. AFLglobal.com | 800.235.3423 The MiniBend miniature fiber optic component employs a revolutionary technology that will change the way you plan and engineer the fiber management in your oil or gas well. This patented technology allows for a single strand of multimode or single-mode fiber to be formed at a 180° bend with a 1 mm fiber bend diameter, saving valuable real estate. Applications • Downhole fiber optic turnaround • Fiber management systems • Modulators, splitters, circulators, connectors and polarizers • Circuit boards and back planes • Compact test instrumentation and sensors Features • Elegant, low profile solution for achieving downhole fiber optic double-ended system • Provides low-loss sub-millimeter bends for miniaturizing fiber components and circuits • No stress with the small bend radii • Bi-directional • Mechanically and environmentally robust • Small and protective package Specifications PARAMETER VALUE Item Number DNS-1574 DNS-1575 DNS-1885 DNS-1890 Fiber Coating Type 50 μm multimode carbon mid-temperature acrylate 50 μm multimode carbon/polyimide single-mode carbon mid-temperature acrylate single-mode carbon/polyimide Operation Wavelength Range 900 to 1340 nm, 1430 to 1600 nm 1280 to 1340 nm, 1430 to 1600 nm Insertion Loss < 0.2 dB at 1310 nm of wavelength at room temperature < 0.3 dB at 1550 nm of wavelength at room temperature Operating Temperature 0 to 150°C 0 to 200°C 0 to 150°C 0 to 200°C Storage Temperature -60 to 85°C Body Size Outside Diameter = 2.2 mm +/-0.1, Length = 15 mm +/-0.3 Fiber Tail Length > 0.5 m Straight Pull 500 g Dimensions MiniBend ® Fiber Optic Component For Downhole Double-ended Systems and Optical Connectivity
