    • A communications cable and method for making same wherein a communications cable is able to withstand significantly higher thermal temperatures than conventional fiber whether it be general purpose, or rated as Plenum/Riser rating, or even MIL Spec type cables. A core fiber glass material with at least an 427 o C (800 Fahrenheit) degree operating ability allows the communications cable to survive in high heat or stress conditions. A polyimide coating on the outside of the fiber is a high temperature resistent material and lends to this high operating temperature capability. By containing and protecting an optical pair of these fibers or even up to 4 glass fibers within a silicone rubber 1 mm diameter buffer tube, thermal protection of the high temperature glass within is increased. A single buffer tube type product and market that as a mini solution for fiber optic requirements within equipment or we individually or group wise mechanically protect these buffer tubes. The choice and decision to apply 2 layers of opposing woven aramid/KEVLAR™ fibers now begins to apply an enhanced tensile strength capability resulting in significant increase of currently available fiber optic cables. Once this mechanical protection layer has been applied, a second, but thicker, layer of silicone rubber is applied as an outer protection jacket either over the single paired Duplex Cable or the 24 Pair or larger cable design.
    • 一种通信电缆及其制造方法,其中通信电缆能够承受比常规光纤显着更高的热温度,无论是通用型,还是额定值为Plenum / Riser额定值,甚至是MIL Spec型电缆。 具有至少427℃(800华氏度)操作能力的核心玻璃纤维材料允许通信电缆在高热或应力条件下生存。 纤维外侧的聚酰亚胺涂层是耐高温材料,具有这种高的工作温度能力。 通过在硅橡胶1mm直径缓冲管内容纳和保护这些纤维的光学对或甚至多达4个玻璃纤维,增加了高温玻璃的热保护。 作为设备中光纤要求的迷你解决方案的单缓冲管式产品和市场,或者我们单独或组织地机械保护这些缓冲管。 应用2层相对的编织芳族聚酰胺/ KEVLAR“¢纤维的选择和决定现在开始应用增强的拉伸强度能力,导致当前可用的光纤电缆的显着增加。 一旦施加了这种机械保护层,第二层但更厚的硅橡胶层被用作外部保护套,可以通过单一双绞线或24对或更大的电缆设计。
