    This report summarizes the results of our research at which we have prepared and fabricated plastic optical fiber successfully. Optical fiber preparation were carried out following the standard method for optical fiber fabrication, i.e. pre-casting method. First, all materials of interest were optically measured. This was done by measuring their refractive index. High refractive index materials were than chosen as core and the lower one was used as cladding. From the UV-VIS-NIR transmission spectra measurement of all samples it is clear that the transmission range of all materials under investigation are wider than the sun transmission spectra captured at the earth surface. As the fiber fabrication method used was pre-casting method, first of all, the fibre material must be tailored into preform (pre-core and pre-cladding). Spin caster, a machine to fabricate pre-cladding that works by making use of centrifugal force has been assembled. This machine has been used and some good results of pre-cladding were already made. Just like in fabricating glass pre-cladding, uniform diameter of pre-cladding was easily resulted when the spinning process was carried out at the condition at which the mould containing polymer liquid/molten of plastics was tilted. At last, a set of fiber drawing tower (a tower used to fabricate optical fiber from the prepared preform) was also made. Wondering if this tower was work, some preforms previously made were put into the furnace located at the upper part of the fibre tower. Furnace was set at a temperature above the glass transition temperature and a load of many kilograms was applied to the heated preform. It was clear that a good uniformity of fiber diameter can be made easier at temperature just above glass temperature if and only if the preform was loaded. Drawing fiber from polymer (plastics water pipe) at 1900C resulted in an optical fiber with diameter of (0.22 ± 0.03) mm. This result is much better than that fabricated at 2500C resulted in fiber diameter of (0.26 ± 0.10) mm. Keywords: Fiber Optics, Fiber Drawing, Polimer Optical Fiber.
