西德Kabelmetal Electro GmbH公司保证光缆在其电视会议通信网络中能够长期最可靠地服务。该公司之所以自信是由于使用了杜邦公司的“Kevlar”聚芳酰胺纤维作为光缆的加强件。以汉诺威为基地的Kabelmetal Electro GmbH公司是西德北方的私营公司,第一个经营这种通信网络。她已看出电视会议通信系统有光辉的前程,几个电视会议的参加者,采用这种通信系统直接可视和通话。通信系统的所有电信号包括电视,声音和数据信号均通过光缆传输。为了确保通信系统的高可靠服务,须保护光缆不受拉伸、压皱和其它物理应力的影响。为此,KabelmetalElectro GmbH公司选用“Keylar”聚芳酰胺纤维作为光缆的加强件,将这种杜邦公司的强度高、重量轻的纤
Kabelmetal Electro GmbH, a company in the West Germany, guarantees that optical cables can serve most reliably and reliably over their teleconferencing communications network. The company is confident it is using DuPont’s “Kevlar” polyaramide fiber as a cable reinforcement. The Hanover-based Kabelmetal Electro GmbH is a private company in northern West Germany, the first to operate such a network. She has seen the glorious future of videoconferencing and communication systems, with participants in several videoconferences using this communications system for direct visualization and conversation. All electrical signals of the communication system, including television, sound and data signals, are transmitted through the optical cable. In order to ensure a highly reliable service of the communication system, the optical cable must be protected from stretching, crushing and other physical stresses. To this end, KabelmetalElectro GmbH chose “Keylar” polyaramide fiber as a cable reinforcement, the DuPont’s high strength, light weight fiber
