iFi SilentPower LAN iPurifier Pro - Ethernet Filter with Optical Isolation

The SilentPower LAN iPurifier Pro is a high-performance Ethernet noise filter with optical galvanic isolation designed to help networked audio and video gear perform at its best. By converting the incoming Ethernet signal to light and back again, it breaks the electrical pathway between your router/switch and your streamer, DAC, media PC, or 4K media box—blocking network-borne noise, stray voltages, and interference that can ride along standard copper Ethernet connections.

Beyond isolation, the LAN iPurifier Pro actively improves signal integrity with signal regeneration plus advanced processing such as adaptive equalisation, error correction, and crosstalk cancellation to support cleaner data transfer and more stable performance. The result is a quieter, more refined presentation for streaming systems and a more reliable connection for demanding home, office, and pro AV installs.

What It's Good At:

• Optical galvanic isolation to stop noise and interference from passing into sensitive AV gear
• Lower jitter and reduced system noise for cleaner, more natural network audio playback
• Signal regeneration for improved timing accuracy and data-stream stability
• Gigabit-ready performance (up to 1000 Mbps) for modern streaming, media servers, and 4K devices
• Real-time diagnostic LEDs for power, link, optical status, and connection speeds (with adjustable brightness)
• Simple plug-and-play integration between your router/switch and your network device

iFi LAN iPurifier Pro Q&A:

Q: What does the LAN iPurifier Pro actually do?

A: It reduces Ethernet-borne noise by converting the network signal to optical (light) and back, electrically isolating your network device from noise and interference coming from the router or switch.

Q: Where should I install it in my network chain?

A: Connect it between your router/switch and the device you want to protect (streamer, DAC network bridge, media PC, 4K box). For best results, place it as close to the target device as possible.

Q: Will it slow down my network speed?

A: No—it's designed to support 1000/100/10 Mbps operation, so it’s compatible with Gigabit Ethernet and typical home/office networks.

Q: Does it work with any Ethernet device or only audio gear?

A: It’s compatible with a wide range of Ethernet-based devices, including routers, switches, general-purpose computers, streamers, and 4K media devices.

Q: Does it need external power to work?

A: Yes. It is powered via USB-C and requires a 5V / 1A supply. A USB power adapter is included.

Q: What are the LEDs telling me on the front panel?

A: The LEDs provide real-time status for power, link/activity, and speed states for both the standard and optical-isolated sides, plus optical connection status.

Q: Can I turn off or dim the LED lights?

A: Yes. Use the brightness button to cycle through High, Low, and Off modes.

Q: Is this mainly for music streaming, or does it help video too?

A: It can benefit both. By reducing noise and improving link stability, it can help demanding streaming setups used for high-quality audio and 4K media playback.
