The result shows that by changing the temperature parameter of core and cladding procedure, different transmission loss the plastic optical fiber which is made of under the procedure is. The plastic optical fiber which is made 圖二 複合紡絲示意圖。 of under the procedure has different transmission loss. Also different the core material is, different the processing optimization of cladding material. We made the cladding material procedure fixed as the processing optimization condition, with the procedure temperature parameter of core material getting lower, the transmission loss of plastic optical fiber appears the tendency of reducing. With the procedure temperature parameter of core material getting lower, plastic optical fiber’ transmission loss shows the reducing tendency. It shows a minimum transmission loss at some temperature. 圖三 塑膠光纖生產流程示意圖。 一、摘要 本研究主要探討以 PC 、PMMA及 PS 為芯層材料，含 製備塑膠光纖首要在原料的選擇，選擇條件首重透光 氟共聚合物 (fluoro copolymer)為皮層材料之塑膠光纖其傳 度，一般使用 90％以上的原料，本實驗採用之原料透光度 輸損耗與最適化加工條件之研究。結果發現藉由改變芯層和 達 92％。再來經由流變儀測試原料其適宜之加工溫度，並 皮層製程之溫度參數，會造成所製備之塑膠光纖有不同的傳 得出原料之流變性質，再因原料而異，以不同的條件去除內 輸損耗值；不同的芯層材料也對應出不同的皮層材料之最適 含水分，最後以複合紡絲的方式，經複合紡絲機測試不同加 化加工條件。將皮層材料製程固定在最適化加工條件下，隨 工條
