Claim 0:
1. A test system for assisting a splicing technician in optical fiber splices, the test system comprising:
a first test unit and a second test unit to be connected toward opposite ends of an optical fiber link comprising a first fiber span and second fiber span to be spliced, each test unit having at least one output port and comprising:
an OTDR acquisition device for performing at least one OTDR acquisition toward said output port in order to test a quality of the splice, wherein each OTDR acquisition is performed by propagating in the optical fiber link under test, a pulsed test signal and detecting corresponding return light from the optical fiber link so as to obtain an OTDR trace representing backscattered and reflected light as a function of distance in the optical fiber link;
a tone generator to produce a tone optical signal toward the output port; and
a tone detector to detect a presence of a tone signal produced by the tone generator of the opposite test unit and received via the output port, in order to test a continuity of the optical fiber link; and

a test application comprising computer instructions to be executed on a wireless portable device used by the splicing technician and in communication with the first test unit and the second test unit, the test application comprising a user interface to display results of continuity tests performed using the first test unit and the second test unit and results of splice quality tests performed by at least one of the first test unit and the second test unit.
