OPTICAL FIBER, AND OPTICAL ACCESS NETWORK, LOCAL AREA NETWORK AND OPTICAL PARTS FOR COMMUNICATION, WHICH USE THE OPTICAL FIBER광섬유와 이를 이용한 광가입자망, 구내 정보 통신망 및통신용 광부품
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 lOμm ~ 40μm has at least two propagation modes
in a wavelength over 1200nm. 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
