PROBLEM TO BE SOLVED: To provide a multimode optical fiber operated in a system designed to transfer information in 1 giga bits/sec. or more of rate, using an LD light source. SOLUTION: The multimode optical fiber includes a core 12 having a refractive index distribution with g(r) as a function, the first laser bandwidth longer than 220 (MHz km) in a 850 nm window, the second laser bandwidth longer than 500 (MHz km) in a 1,300 nm window, the first OFL bandwidth of at least 160 (MHz km) in the 850 nm window, and the second OFL bandwidth of at least 500 (MHz km) in the 1,300 nm window, r represents a radius of the core, and the g(r) varies from a large value in the vicinity of the center of the core to a small value in an outer part of the core.

Abstract:
A single mode waveguide coupling to a multimode fiber (14) of a high-bandwid th local optical network is made by a tapered coupler (10) that expands the spo t size of the propagating beam to fill additional modes of the multimode fiber . The tapered coupler has a core (30) surrounded by inner (32) and outer (34) layers of cladding. The core and the inner cladding layer are drawn down alo ng their length to force light from the core into the surrounding inner claddin g layer. The outer cladding layer confines the expanded beam within the core a nd inner cladding layer.
