With the rapid development of fibre-to-the-home and data centers, as pipeline resources are becoming scarce, it is urgent to increase the density of optical fibres and lay in limited space the optical cables that contain more fibre cores. By reducing the thickness of the outer cladding and coating of fibres while keeping the diameter of fibre core unchanged, YOFC is able to make optical fibres with small outer diameters.

YOFC's diameter-reduced fibre can be customized in terms of MFD, cut-off wavelength, outer diameter, and cladding diameter in accordance with customer requirements. Its cross sectional area can reach only 50% of that of conventional fibre or even less, as a result of which the density of optical cable may significantly increase. It is suitable for high-density, small OD optical cables and the optical devices with narrow internal space and small fibre bend radius.
