Abstract: Optical fiber line is an important device in optical
communication system, and also the basic network. This paper
introduces the role of optical fiber line in optical communication
system, and detailedly expounds the causes of signal
transmission loss in joint of optical fiber line. Combining with
practical work experience, the author finds out thatthe signal
transmission attenuation of optical cable communication lines is
