The SilentPower OMNI USB is an optical USB isolator paired with active noise reduction. The supplied USB OptiLink converts the incoming data signal into light via optical isolation; it is retransmitted to the OMNI USB and reconverted, completely isolating input from output. Electrical noise, interference and leakage currents are eliminated at the source.

The OMNI USB offers five PurePort outputs with active noise reduction: four USB-A and one USB-C. A 192 kHz/24-bit converter provides coaxial and optical outputs for older DACs or CD players, while a 10 MHz clock input precisely synchronizes a DAC to refine timing and soundstage.

An 8000 mAh lithium-ion battery completely isolates the device from the mains, with up to fifteen hours of runtime. Intelligent charging electronics maintain the battery between 20 and 80% to preserve it. USB 3.2 connectivity delivers speeds up to 10 Gbit/s and PD3.0 charging continues to fast devices.

A display visualizes voltage fluctuations and noise reduction effectiveness in real time. The rear panel adds optical inputs for SFP modules (10G and 1.25G), optical and coaxial outputs, and a power input. The OMNI USB measures 21.4 × 15.8 × 4.1 cm and weighs 1.19 kg; the OptiLink, SFP modules, cables and a 15 V power supply are included.
