Publication number: 20130084048Abstract: The present invention relates to a multi-mode optical fiber having a structure to reduce the numerical aperture at the emission end of the multi-mode optical fiber having a length for which practical use is assumed. The multi-mode optical fiber comprises a core portion, a trench portion, and a cladding portion. The multi-mode optical fiber is designed such that the numerical aperture at the emission end thereof is reduced as the fiber length increases, and moreover such that the numerical aperture of the multi-mode optical fiber having a length for which practical use is assumed satisfies a specific condition. By this means, the numerical aperture at the emission end of the multi-mode optical fiber can be kept small, and coupling efficiency of the multi-mode optical fiber with other optical components is drastically improved.Type: ApplicationFiled: September 29, 2011Publication date: April 4, 2013Applicant: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Itaru SAKABE, Kazuyuki Soma, Tomoyuki Hattori
