The Reiki Audio OpticalBridge Plus or PRO eliminates network noise by converting your ethernet connection to optical, requiring no infrastructure changes—simply run a short optical cable alongside existing wiring. Pair two OpticalBridge units or connect one directly to an SFP-equipped router and streamer. Each unit features precision-engineered audiophile components: a 5mm milled aluminum chassis with dual copper shielding, discrete ethernet magnetics, silver-plated OFC internal wiring, and weight-specific isolation feet. Includes low-noise SFP modules, optical cables (0.5m and 1m), CAT6 ethernet cables, and external low-noise power supply. Single ethernet and SFP port configuration with optional grounding post. No LEDs or unnecessary openings preserve signal integrity at the critical final stage before your audio streamer. Plus or PRO? The Plus models include an iFi iPower ultra low noise PSU for a modest price increase (and cheaper than buying one elsewhere at RRP).   The PRO is our ultimate model and comes with one of our custom-designed fully linear PRO linear PSUs.  Our shop includes the following pre-configured OpticalBridge: ·      OpticalBridge PRO/PRO Extreme -  2x OpticalBridge units, 2x PRO linear PSU Each OpticalBridge unit comes with the required SFP module and each pair of units comes with a 50cm or 1m Single Mode optical cable.
