Polarization Maintaining Telecommunication Fibers The breadth of Nufern’s range of Polarization Maintaining fibers is unrivaled. Designed for use from 980 to 1620 nm, these fibers are used in all PM applications for data and telecom. Nufern has applied its unique manufacturing facility and capabilities to this product area and has made substantial optical, mechanical and geometrical tolerance improvements. Furthermore, higher strength and fatigue failure resistance allows customers to achieve more uniform product results and to attain the highest possible manufacturing yields. Typical Applications Features & Benefits • Lithium niobate modulators, • Tight specifications — Highly deterministic results, highest product yield PMD compensators • Raman gain modules • Pigtailing Optical Specifications Operating Wavelength Core NA Mode Field Diameter Cutoff Core Attenuation Beat Length Normalized Cross Talk • High proof test — Low risk of mechanical handling failure • High fatigue failure resistance — Longest service life PM980-XP PM1300-HP 970 – 1550 nm 0.120 6.6 ± 0.7 µm @ 980 nm 920 ± 50 nm ≤ 2.5 dB/km @ 980 nm ≤ 2.7 mm @ 980 nm ≤ - 40.0 dB at 4 m @ 980 nm ≤ - 30.0 dB at 100 m @ 980 nm 1270 – 1625 nm 0.120 9.5 ± 1.0 µm @ 1300 nm 1200 ± 70 nm ≤ 1.0 dB/km @ 1300 nm ≤ 4 mm @ 1300 nm ≤ - 40.0 dB at 4 m @ 1300 nm ≤ - 30.0 dB at 100 m @ 1300 nm 125.0 ± 1.0 µm 5.5 µm 245.0 ± 15.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) 125.0 ± 1.0 µm 8.0 µm 245.0 ± 15.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) Geometrical & Mechanical Specifications Cladding Diameter Core Diameter Coating Diameter Coating Concentricity Core/Clad Offset Coating Material Operating Temperature Range Prooftest Level 7 Airport Park Road, East Granby, CT 06026 • 860.408.5000 • Toll-free 866.466.0214 • Fax 860.844.0210 E-mail info @ nufern.com • www.nufern.com Nufern products are manufactured under an ISO 9001:2008 certified quality management system.
