Description

[Detailed description of the invention] The present invention relates to an optical fiber link device, and more specifically to an optical fiber link device that can easily realize optical fiber transmission lines by using conventional multi-core connectors as they are. .

Multi-core cables made of metal conductors are normally used for transmission lines for exchanging signals between the main body of a computer and peripheral devices, but there is a trend toward replacing them with multi-core optical fiber cables for purposes such as countermeasures against electromagnetic induction. It is in. However, when replacing a metal conductor multicore cable with a multicore optical fiber cable, an electrical signal-to-optical signal converter is inevitably required, which requires extra space and reduces the space available to the main unit and peripheral devices. It is difficult to attach and detach cables to make them as compact as conventional metal conductor connectors, and it is also considerably difficult to convert standardized connectors into optical fibers.

This invention was developed as a result of intensive studies in view of the above circumstances, and uses a metal conductor cable and a metal conductor cable connector at both ends of an optical fiber transmission line, and connects the main unit, peripheral devices, and the cable. The existing connector can be used for attachment and detachment, making it easy to use optical fiber as a transmission line.

That is, the present invention includes a device for converting an electrical signal into an optical signal or an optical signal into an electrical signal (hereinafter referred to as a converting device), a frame equipped with a grid-shaped housing part that removably houses the converting device, and The conversion device comprises an optical fiber link device comprising means for connecting a metal conductor cable on one side and means for connecting an optical fiber cable on the other side. be.
