Precision starts at the network level
When electrical interference travels through your network’s cabling alongside digital data, it wreaks havoc, disrupting timing during conversion and degrading audio and video playback. At Sweetwater, we’ve found these electrical pitfalls especially detrimental to the overall performance of your digital device. The LAN iPurifier Pro addresses electrical interference through optical isolation and signal regeneration, eliminating timing jitter and restoring reliable, accurate performance in components such as music streamers, 4K media boxes, and media streaming PCs.




A superior approach to network isolation
Rather than relying on transformer-based designs, the iFi LAN iPurifier Pro takes a fundamentally different approach, employing optical galvanic isolation to convert incoming network data, which is delivered as an electric signal, into light. It then transmits the light across an optical barrier and reconverts it back into an electrical signal for the final leg of its journey to your critical components. By completely severing all electrical pathways between input and output, the LAN iPurifier Pro provides a level of isolation that conventional approaches simply can’t match, blocking common-mode noise, stray voltages, and bloodsucking capacitance that would otherwise threaten signal purity.
Bit-perfect signal reconstruction
After passing through the LAN iPurifier Pro’s optical isolation stage, the data stream is fully reconstructed using active circuitry. This process ensures bit-perfect signal integrity by stripping away any distortion or interference that may have compromised your digital signal. The result is a pristine, uninterrupted data stream with minimal jitter and rock-solid system timing.
