Abstract:
An optical fiber, and an optical access network, a local area network and optical parts for communication, which uses the optical fiber, are disclosed. The optical fiber whose core diameter is 10 μm˜40 μm has at least two propagation modes in a wavelength over 1200 nm. The optical fiber according to the present invention can reduce packaging costs for optical components, since cross-sectional area of the core is large, compared with the prior art technique adopting a single mode optical fiber, and can transmit ultra-high speed data a relatively long distance, since the mode number and modal dispersion effect of the optical fiber is relatively small, compared with the prior art multimode optical fiber. Also, when using the optical fiber according to the present invention, the optical subscriber network and the local area network can be cost-effectively implemented. In addition, when adopting the optical fiber according to the present invention, productivity of optical components for communication can be improved, costs for an optical component can be reduced and quality of the optical component can be improved.
