Polarization Maintaining Telecommunication Fibers with 400 µm Coating The breadth of Nufern’s range of Polarization Maintaining fibers is unrivaled. Designed for use from 980 to 1620 nm with 400 µm dual acrylate coating, these fibers are used in 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 (prooftested to > 200 kpsi) and improved 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, PMD • Tight specifications — Highly deterministic results, highest product yield compensators • Raman gain modules • Pigtailing • High fatigue failure resistance — Longest service life • High proof test — Low risk of mechanical handling failure • Robust 400 µm dual acrylate coating • All fiber proof tested to > 200 kpsi — Critical for ensuring long term reliability when coiling Optical Specifications Operating Wavelength Operating Wavelength (nominal) Core NA Mode Field Diameter Cutoff Core Attenuation Beat Length Normalized Cross Talk PM980-400 PM1300-400 PM14XX-400 PM1550-400 970 – 1550 nm N/A 0.120 6.6 ± 0.7 µm @ 980 nm 920 ± 50 nm ≤ 2.5 dB/km @ 980 nm N/A 1300 nm 0.120 9.0 ± 0.5 µm @ 1300 nm 1200 ± 70 nm ≤ 1.0 dB/km @ 1300 nm 1490 – 1620 nm N/A 0.125 10.5 ± 0.5 µm @ 1550 nm 1370 ± 70 nm ≤ 1.0 dB/km @ 1550 nm ≤ 2.7 mm @ 980 nm ≤ - 40.0 dB at 4 m @ 980 nm ≤ - 30.0 dB at 100 m @ 980 nm ≤ 4 mm @ 1300 nm ≤ - 40.0 dB at 4 m @ 1300 nm ≤ - 30.0 dB at 100 m @ 1300 nm 1390 – 1625 nm N/A 0.125 9.8 ± 0.5 µm @ 1450 nm 1320 ± 60 nm ≤ 1.0 dB/km @ 1450 nm ≤ 1.0 dB/km @ 1550 nm ≤ 4.7 mm @ 1450 nm ≤ - 40.0 dB at 4 m @ 1550 nm ≤ - 30.0 dB at 100 m @ 1550 nm 125.0 ± 1.0 µm 5.5 µm 400.0 ± 15.0 µm ≤ 0.50 µm -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) 125.0 ± 1.0 µm 8.0 µm 400.0 ± 15.0 µm ≤ 0.50 µm -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) 125.0 ± 1.0 µm 8.0 µm 400.0 ± 15.0 µm ≤ 0.50 µm -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) 125.0 ± 1.0 µm 8.0 µm 400.0 ± 15.0 µm ≤ 0.50 µm -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) ≤ 5.0 mm @ 1550 nm ≤ - 40.0 dB at 4 m @ 1550 nm Geometrical & Mechanical Specifications Cladding Diameter Core Diameter Coating Diameter Core/Clad Offset Operating Temperature Range Prooftest Level These fibers are also available with 250 µm coating. 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.
