随着有线电视的迅速发展和普及,用光缆进行县至乡镇联网已成为有线电视超干线传输的主流。但是如何减小光路损耗,这是进行设计、设备选型、施工等方面值得注意的问题。今年5月份,我们与南通中天电缆有限公司在架设县城至马塘25.6km光缆线路中,就如何减小光纤接头熔点损耗进行了探讨。 With the rapid development and popularization of cable television, the county-to-township networking with optical fiber cables has become the mainstream of CATV super-channel transmission. However, how to reduce the optical path loss is an issue worth noting in terms of design, equipment selection and construction. In May this year, we and Nantong transit Cable Co., Ltd. in the erection of the county to Matang 25.6km optical cable line, on how to reduce the melting point loss of optical fiber connectors were discussed.
