从透光率计算氟化物玻璃的光损耗来看,氟化物损耗的理论极限值竟达石英玻璃的百分之一以下,即每公里0.001分贝。目前,石英玻璃光纤100公里无中继传输成功的实验实例已有报导,根据计算氟化物光纤有可能获得1万公里无中继传输,认为对海底光缆特别有效。将来有可能生产出日美之间1万公里无中继传输用的光纤。作为光纤材料,在期待低损耗的同时,光纤加工时
Judging from the optical loss of the fluoride glass calculated from the transmittance, the theoretical limit of the fluoride loss is as high as one percent or less of the silica glass, that is, 0.001 dB per kilometer. At present, experimental examples of successful transmission of 100 km quartz glass optical fiber without repeater have been reported. According to the calculation of fluoride optical fiber, it is possible to obtain 10,000 km uninterrupted transmission and it is considered to be particularly effective for submarine optical cable. In the future, it is possible to produce 10,000 km of fiber for relayless transmission between Japan and the United States. As a fiber material, expect low loss at the same time, optical fiber processing
