摘要

A transmission-side transport device (40) comprises a first transmitter (20) having a first switch (21), and a second transmitter (30) having a second switch (31). When the first transmitter (20) detects a fault in a first main signal, the second transmitter (30) outputs a duplicated signal of a second main signal to the first transmitter (20). The first transmitter (20) selects, in a first selector (22), and outputs the inputted duplicated signal of the second main signal. Upon detecting a fault in the first switch (21), the second transmitter (30) selects and outputs the second main signal.
