System for optical data interconnection

Abstract

A system for optical data interconnection of a source and a target includes a first HDMI compatible electrical connector capable of receiving electrical signals from the source. A first signal converter is connected to the first HDMI compatible electrical connector and includes electronics for converting the TMDS electrical signal into an optical signal, and the electronics include an optical conversion device connectable to a source ground to reduce noise. At least one optical fiber is connected to the first signal converter. A second signal converter is connected to the at least one opticalfiber and includes electronics for converting the optical signal to a TMDS electrical signal. A power supply module for a second signal converter provides power to an electrical signal amplifier connectable to a target ground. A second HDMI compatible electrical connector is connected to the second signal converter and is capable of transmitting a signal to the target.

Description

[0001] Priority Application Information [0002] This application is based on U.S. Provisional Application No. 62 / 817,225 (“Optical Data Interconnect System”) filed March 12, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to systems for optical interconnects. In particular, a system and method for simulating an electrical HDMI interconnect to an optical system is described. Background technique [0004] High Definition (HD) signals are typically transmitted from one system to the other using cables carrying DVI (Digital Visual Interface) or HDMI (High Definition Multimedia Interface) signals. Conventionally, DVI / HDMI signals are conveyed over copper cables using Transition Minimized Differential Signaling (TMDS). In TMDS, video, audio and control data can be carried as 24-bit words on three TMDS data channels and a separate TMDS channel for clock information. It can also be carried on four T...

AI Technical Summary

Problems solved by technology

Unfortunately, over long distances (e.g. 5 meters or more), the impedance of copper cables can cause large signal losses leading to artifacts (such as pixelation, optical flare or flicker) or even picture loss

These artifacts can be reduced by passive connection designs involving large or well-shaded copper cables, but this is expensive, bulky, and limits cable flexibility

Alternatively, active electronic modules such as signal boosters can be used to reduce signal loss, but these techniques are also expensive and can lead to the introduction of signal errors
