The fusion splicer includes a first holding unit, a second holding unit, a screen, a first measurement device, a first driving unit, a second driving unit, and a third driving unit. The screen has a light guide portion through which only test light emitted from one of the plurality of cores of the first optical fiber can pass. The screen is disposed between the end face of the first optical fiber and the end face of the second optical fiber. The first measurement device measures the intensity of leakage light leaking from the second optical fiber. The third driving unit adjusts the position of the screen such that the light guide portion is aligned with one of the plurality of cores of the first optical fiber in the axial direction of the first optical fiber.

Fusion splicer and fusion splicing method

A cable with connectors includes a plurality of electric wires arranged in parallel, and a first connector and a second connector provided at each end of the electric wires. The first connector includes a first substrate accommodated therein and a connector plug connected to the first substrate. The second connector includes a second substrate accommodated therein and a connector plug connected to the second substrate. The first substrate and the second substrate have a plurality of first contact points arranged at one end-side thereof and to be connected with the electric wires, respectively. The plurality of first contact points is arranged so that am arrangement order of the plurality of first contact points provided on the first substrate and an arrangement order of the plurality of first contact points provided on the second substrate are mirror-symmetric with the electric wires being interposed therebetween.
