Abstract:
1. An optical time domain reflectometer comprising: a display unit which is configured to display optical fiber management information on a plurality of optical fibers serving as measuring objects in a tabular form; an operating unit which selects an arbitrary optical fiber to be measured from the display of the optical fiber management information; a storage unit which is configured to store various characteristics of the arbitrary optical fiber selected by the operating unit such that measured data of the various characteristics of the arbitrary optical fiber which have been measured based on corresponding optical fiber management information and the corresponding optical fiber management information are associated with one another, wherein the display unit is capable of displaying in a predetermined form, the measured data of the various characteristics of the arbitrary optical fiber and the corresponding optical fiber management information which have been stored in the storage unit so as to be associated with one another; table file reading means for reading from outside a table file which is for carrying out association of said plurality of optical fibers with respective measured data when said plurality of optical fibers have been measured based on the optical fiber management information provided in advance of undertaking a cable laying/maintenance construction, the optical fiber management information including various types of information on said plurality of optical fibers, and information on a construction site, and the table file being created such that the association of said plurality of optical fibers with the respective measured data when said plurality of optical fibers have been measured can be edited at a time of undertaking the cable laying/maintenance construction; table file editing means for editing the table file read by the table file reading means; and optical fiber characteristic measuring means for measuring the plurality of optical fibers based on the table file read by the table file reading means and the table file edited by the table file editing means, wherein the storage unit includes: wherein the display unit is capable of selectively displaying at least a screen in a tabular form on which said plurality of optical fibers are displayed so as to be visible at one view in accordance with the table file read by the table file reading means, and a screen on which said plurality of optical fibers measured by the optical fiber characteristic measuring means, and the respective measured data of said plurality of optical fibers are displayed so as to be associated with one another, and wherein the table file editing means is capable of editing the table file by displaying on the display unit at a time of editing the table file, the screen in the tabular form on which said plurality of optical fibers are displayed so as to be visible at one view.
