POF CablePOF (Plastic Optical Fiber) products are large diameter assemblies constructed of acrylic and fluorinated polymers, for the core and cladding respectively. Similar to traditional glass fiber, POF transmits light/data through the core of the fiber. However, POF assemblies have a core size, in some cases, 100x that of glass fiber. The increased core diameter allows 96% of the core to transmit signal from point-to-point, making it an ideal material for very high bandwidth/signal transmission over very short distances.
塑料光纤,Plastic Optical Fiber。塑料光纤(POF)是由高透明聚合物如聚苯乙烯(PS)、聚甲基丙烯酸甲酯(PMMA)、聚碳酸酯(PC)作为芯层材料,PMMA、氟塑料等作为皮层材料的一类光纤(光导纤维)。不同的材料具有不同的光衰减性能和温度应用范围。制作POF主要的材料有两类:一类是聚甲基丙烯酸甲酯聚合物PMMA(Polymer Polymethylmethacrylate);另一类是含氟聚合物(Perfluorinated polymers )。塑料光纤不但可用于接入网的最后100~1000米,也可以用于各种汽车、飞机等运载工具上,是优异的短距离数据传输介质。

而塑料光纤(POF)的直径大,为1mm,很易于实现光纤的端接、耦合以及布放施工,对线缆最小弯曲半径、安装环境要求也低,所以在高档的全光布线系统、千兆网络系统中以及防干扰、防信号泄漏的布线系统工程中,可以比其它类型的传输线缆更具优势。
塑料光纤的另外一个突出优点是在波长为650nm的可见红光下传输,不会对肉眼造成伤害,适合于安装在居民家中,可与石英光纤配合实现全光网络;而石英光纤是在近红外光下传输,如果直视会对眼睛造成极大伤害甚至失明;另外石英光纤为玻璃制成,碎屑也会对人体造成一定的伤害,因此石英光纤不适合安装在居民家中组建全光网络。
