美国杜邦公司宣称,就选用的通信技术来说,敷设于特拉华州纽卡斯尔郡的一条光纤网络是独一无二的。在纽卡斯尔郡已敷设的许多私人拥有的音频/数据光纤网络,其传输速度较慢(如90Mb/s的新DEC网络)。因此,杜邦公司计划安装AT＆T技术服务部的417Mb/s光纤网络。该网络的传输速率于1986年可提高到1.7Gb/s,质量改进计划将于1987年或1988年完成。杜邦公司的这条网络将是美国国内非长途通信中传输
DuPont claims that a fiber-optic network laid out in Newcastle, Delaware, is unique to the communications technology of choice. Many of the privately owned audio / data fiber optic networks that have been deployed in Newcastle have slower transmission speeds (eg 90Mb / s new DEC network). As a result, DuPont plans to install the 417Mb / s fiber optic network at AT & T Technical Services. The network transmission rate in 1986 can be increased to 1.7Gb / s, quality improvement plan will be completed in 1987 or 1988. This network of DuPont companies will be the transmission of non-long-distance communications in the United States
