日本KDD研究和发展实验室已研制出测量光纤损耗极小变化的装置,它在5小时内长期稳定性已达到±0.01分贝。测量了单模光纤连接器中由温度变化所致的较小损耗变化情况。该装置已被用来研究海底光缆系统。
Japan KDD Research and Development Laboratory has developed a device for measuring small changes in fiber loss, long-term stability within 5 hours has reached ± 0.01 dB. Single-mode optical fiber connector was measured by the temperature changes caused by the smaller loss changes. The device has been used to study submarine cable systems.
