Claim Text:
1. A method of simultaneously measuring at least one parameter of a plurality of cores in at least one optical fiber to be tested, comprising the steps of: a) preparing an input tester having i) a plurality of tester signal inputs with a geometry substantially matching at least a portion of the core geometry of the fiber to be tested, and ii) at least one test input signal source coupled to the plurality of tester signal inputs; b) aligning the plurality of tester signal inputs with the corresponding plurality of cores in the fiber to be tested at a first end of the fiber to be tested; c) firing at least one test input signal from the test input signal source through the input tester to the plurality of cores in the fiber being tested; and d) measuring the output of the test input signal emerging from a second end of the fiber being tested, wherein the input tester includes a laser and the tester signal inputs include apertures in a shield disposable between the laser and the first end of the fiber to be tested.
