我院工程光学系与天津大学电子工程系及光纤技术研究所共同研制的BT-1986光导纤维广播式声象网络于一九八七年五月由机械委教育局主持通过了技术鉴定。 该网络是目前国内第一条进行鉴定的试验性光纤广播式声象局部网,首次在我国采用活动式光纤耦合器、活动连结器及Y分路器,使得组网、折网灵活方便。经过一年多的实际 BT-1986 Optical Fiber Broadcasting Network was jointly developed by Department of Engineering Optics of Tianjin University and Tianjin Institute of Electronic Engineering and Optical Fiber Technology Institute and passed the technical appraisal in May 1987 by the Bureau of Mechanical Education. The network is the first experimental local experimental fiber-optic broadcast local audio network, the first time in our country with active fiber coupler, active connector and Y splitter, making networking, folding network flexible and convenient. After more than a year of actual
