Abstract

An optical pulse tester includes: an OTDR measurer configured to execute an OTDR function of measuring a time distribution of a power of return light of an optical pulse input to an optical fiber; a display configured to display an OTDR measurement screen indicating information on execution of the OTDR function; and a controller configured to control the OTDR measurer and the display. The controller displays, on the OTDR measurement screen, a menu for allowing an operating person to call an auxiliary function for measurement of the optical fiber, and displays, on the OTDR measurement screen, a sub-screen indicating information on execution of the auxiliary function called by the operating person.

First claim

What is claimed is:

1. An optical pulse tester comprising:
an OTDR measurer configured to execute an OTDR function of measuring a time distribution of a power of return light of an optical pulse input to an optical fiber;
a display configured to display an OTDR measurement screen indicating information on execution of the OTDR function; and
a controller configured to control the OTDR measurer and the display, wherein
the controller displays, on the OTDR measurement screen, a menu for allowing an operating person to call an auxiliary function for measurement of the optical fiber, and
displays, on the OTDR measurement screen, a sub-screen indicating information on execution of the auxiliary function called by the operating person.

2. The optical pulse tester according to claim 1 , wherein
the auxiliary function includes at least one of a stabilized light source function of continuously emitting measurement light, a visible light source function of emitting visible light, an optical power meter function of measuring a power of light emitted from the optical fiber, and a fiber end face inspection function.

3. The optical pulse tester according to claim 1 , wherein
the controller pops up the menu according to a predetermined operation of the operating person.

4. The optical pulse tester according to claim 1 , further comprising:
a first port for the OTDR function;
a second port for the auxiliary function for the measurement of the optical fiber; and
an auxiliary function executer configured to execute the auxiliary function for the measurement of the optical fiber, wherein
the controller controls the auxiliary function executer.

5. The optical pulse tester according to claim 4 , wherein
the controller controls the auxiliary function executer according to an execution instruction of the operating person input to the sub-screen, and executes the called auxiliary function.

6. The optical pulse tester according to claim 5 , wherein
the controller executes the OTDR function and the auxiliary function in parallel.
