October 14, 2004 Seoul -- Samsung Electronics announced today improvements in the geometrical specifications of its multimode optical fibers.
Significant advancements have been made for seven major geometrical specifications, resulting in what Samsung claims are four world records. The clad diameter tolerance has been improved by 33% from 125 ± 1.5 µ m to 125 ± 1.0 µ m. The core-clad concentricity error has been reduced by 50% from the previous ≤ 3.0 µ m to ≤ 1.5 µ m. The coating diameter tolerance has been also improved by 50% from 245 ± 10 µ m to 245 ± 5 µ m, which is best-in-class performance, says the company.
Furthermore, Samsung asserts that it has established the world-best geometrical specifications in the area of core non-circularity, clad non-circularity, coating non-circularity, and coating-clad concentricity error for its fiber. The company has presented ≤ 3.0% for core non-circularity, which is 40% better than the current industry standard of ≤ 5.0%.
Additionally, the clad non-circularity has been improved from ≤ 2.0% to ≤ 0.8%, 20% superior to the current standard of 1.0%, and coating non-circularity has been improved by 50% from ≤ 6.0% to ≤ 3.0%, which is another world-best specification and 40% better than the present best-in-class specification of ≤ 5.0%. The company also improved coating-clad concentricity error by more than 50% from ≤ 12.5 µ m to ≤ 6.0 µ m,
"This announcement once again demonstrates Samsung's strong will and commitment to quality and ever growing customer's requirements for more advanced fiber quality," contends Byeong-Bok Jeon, vice president and general manager of the Samsung Fiberoptics Division.
Samsung delivers standard multimode fibers in various offerings with bandwidth performance of up to ≥ 600/1,200 MHz-km and attenuation behavior of ≤ 2.4/0.6 dB/km for the corresponding premium grades.
Samsung is also working to improve the specifications of its laser-optimized multimode fiber.
