Description

[Detailed description of the invention] The present invention relates to a fiber terminal arrangement device for a multi-core cable, and is particularly suitable for use when arranging one end of a large number of core wires based on the arrangement order of the other ends. The present invention relates to a fiber terminal arrangement device for a multi-core cable.

When wiring within a device or between devices in a computer or the like, it is necessary to connect one group of terminals to be connected to the other group of terminals in a predetermined relative relationship.
