A tubular system comprises a flexible insertion part, a tubular device (100), further comprising a physical quantity detector (111), a physical quantity detector signal processing box (300) which processes a signal of the physical quantity detector (111), and a detachable connection cable (200) which connects the tubular device (100) and the physical quantity detector signal processing box (300). The physical quantity detector (111) further comprises an optical waveguide which is positioned in the insertion part. The connection cable (200) further comprises a light source (211) which supplies light to the optical waveguide of the physical quantity detector (111), a light detector (214) which detects light which is modulated by the physical quantity detector (111), a light entry/exit unit (213) which carries out receiving of a light signal with the physical quantity detector (111), and an electrical I/O unit (215) which carries out receiving of an electrical signal with the physical quantity detector signal process box (300). |
