| 英文摘要 | A transmission line testing method for testing the transmission loss between a master station and a slave station additionally provided to a star communication system, a slave station using the method, a master station, and an optical communication system. In a transmission line under test of a star communication system, the power of a signal is measured at a second end to which a slave station to be provided additionally is connected and a first end other than the second end by second and first measuring means respectively, and the result of the measurement at the first end is stored in storage means. Alternatively, the result of the measurement at the first end is transmitted to accommodating means by transferring means. The accommodating means accommodates the result of the measurement at the first end in a downstream signal and transmits it to the slave station. In the slave station, information extracting means extracts the result of the measurement at the first end from the downstream signal, and processing means calculates the difference between the measurement results at the first and second ends, thereby calculating the transmission loss of the transmission line under test between the first and second ends. |
