Low birefringent PANDA Feature Stress applying parts (SAPs) with wide interval suppress cladding modes and lower excess loss for use as a fused optical fiber coupler. SAPs with wide interval result in low birefringence. Applications Polarization maintaining fused optical fiber coupler Common specifications Concentricity error ≤ 0.5 μm Cladding diameter 125 ± 1 μm (Major diameter) Polarization crosstalk ≤ -30 dB/100m @ each operating wavelength Minimum bending radius 2% proof : R20 mm Coating structure UV curable acrylate Coating diameter 245 ± 15 μm Product list Product Operating Mode field wavelength diameter SM63-PR-U25D-H 630 nm band SM98-PR-U25D-H 980 nm band SM13-PR-U25D-H 1300 nm band SM14-PR-U25D-H 1400 nm band SM15-PR-U25D-H 1550 nm band Attenuation 4.5 ± 0.5 μm ≤ 12 dB/km @ 630 nm @ 630 nm 6.6 ± 0.5 μm ≤ 3.0 dB/km @ 980 nm @ 980 nm 9.0 ± 0.5 μm ≤ 1.0 dB/km @ 1300 nm @ 1300 nm 9.8 ± 0.5 μm ≤ 1.0 dB/km @ 1450 nm @ 1450 nm 10.5 ± 0.5 μm ≤ 0.5 dB/km @ 1550 nm @ 1550 nm Specifications are subject to change without prior notice Cutoff wavelength 0.50 - 0.62 μm 0.80 - 0.95 μm 1.11 - 1.27 μm 1.26 - 1.38 μm 1.30 - 1.44 μm Beat length 1.5 - 3.5 mm @ 630 nm 2.8 - 4.9 mm @ 980 nm 3.8 - 5.6 mm @ 1300 nm 4.1 - 7.3 mm @ 1450 nm 4.4 - 7.8 mm @ 1550 nm Optical Device Sales Engineering Department 1440, Mutsuzaki, Sakura, Chiba 285-8550, Japan Tel: +81 43 484 0982 FAX: +81 43 484 2186 http://www.fujikura.co.jp/ [email protected] B-13D0086-17
