本研究中對於尼龍與碳纖維複合材料、液晶聚合物與碳纖維複合材料、三種不同編織方式(單一方向、平織、斜織)之碳纖維織布複合材料以及液晶聚合物與奈米碳管複合材料，比較其製作方法、近場與遠場電磁屏蔽效益、以及運用在光電收發模組封裝外殼之重量及成本等。
研究結果發現，以二維方式建構導電網路之[平織]及[斜織] 碳纖維織布複合材料在近場與遠場的電磁屏蔽效益量測中有最好的結果，並且具有重量輕、成本低以及容易製作的特點。此外，將其運用於光電收發模組輻射耐受的測試亦有不錯的結果。因此，碳纖維織布複合材料所製作之封裝外殼可以有效的降低成本並運用於光波傳送系統之電磁干擾防護中。

We investigate the EM properties of four different type composites which are nylon and liquid-crystal polymer with carbon fiber filler composites, woven continuous carbon fiber epoxy composites(balanced twill structure, plain weave structure, uni-direction weave structure), and liquid-crystal polymer with carbon nanotubes filler composites.
By comparison of fabrication methods, cost and weight of the optical transceiver module housings, and shielding effectiveness under plane wave and near-field conditions, the woven continuous carbon fiber epoxy composites(balanced twill structure and plain weave structure) show lower cost, lighter weight, and higher EM shielding effectiveness than the other types of composites. Furthermore, they also perform good radiation susceptibility in our measurements.
For these reasons, the proposed woven continuous carbon fiber epoxy composite package for an optical transceiver is suitable for use in a low-cost light wave transmission system.
