  • Publication number: 20100283997
    Abstract: The specification discloses test device, system, and method for optic fiber cable connections. A light-emitting element emits a light signal, and a light-receiving element receives the light signal. When no electrical signal is received within a predetermined time, the central processing unit generates a random delay time for the light-emitting element to wait for the random delay time before re-emitting the light signal for a connection test. The invention solves the problem of difficulty in locating wrong corrections of optic fiber cables. It can quickly check whether the optic fiber cables are correctly connected.
