The ADOT ONI-100 isolates your audio system from noisy home networks using internal fibre optic technology. It blocks interference picked up by Ethernet cables, reducing timing errors and improving sound quality. Compatible with standard RJ45 connections, it’s easy to install and delivers cleaner, more accurate audio performance for any hi-fi system.
 
ADOT ONI-100 Optical Network Isolator
The ADOT ONI-100 is a high-performance network isolator designed to eliminate electrical noise from your home Ethernet connection, protecting your audio system from unwanted interference. Home network wiring often acts as an antenna, picking up noise from TVs, chargers, and power supplies, which can degrade sound clarity and introduce timing errors.
Using advanced fibre optic isolation, the ONI-100 completely breaks the conducted signal path while maintaining accurate data transmission. This prevents noise from entering your sensitive hi-fi equipment, ensuring a cleaner, more precise sound experience.
Based on the proven ADOT MC01 fibre technology, the ONI-100 brings the same benefits to systems using standard RJ45 connectors. Installation is effortless—just connect using a pair of RJ45 cables and enjoy instant isolation.
 
By isolating your hi-fi network connection, the ONI-100 allows your audio system to perform at its true potential, free from electrical noise and jitter. Experience a smoother, more natural soundstage and improved musical detail with this simple, effective solution.

Why use the ONI-100?
ADOT developed the concept of using Fibre Optics to isolate this noise while rebuilding and retaining the music data with the launch of the ADOT MC01. The ADOT MC01 concept is improving systems worldwide, by using SFP connectors for connectivity. But most home networks, hifi components and even audiophile switches, use conventional RJ45 connectors. The ADOT ONI-100 offers all the advantages of ADOT MC01 in a simple device that connects using a pair of standard RJ 45 network cables. The optical isolation is all performed internal on the ONI-100, keeping the installation simple and tidy.
