System Configuration Guide

Configuration 1: Single Port Streaming Hub (Ethernet-to-Fibre, Fibre-to-Ethernet Isolator)

  • Path: Internet Router -> Ethernet -> effe-01 -> Audio Streamer Ethernet Port.

  • Internal fibre cable, simple and effective, achieving 100% galvanic isolation between the noisy network and streamer.

  • This directly targets modern high-end streamers without SFP port.

Configuration 2: Single Unit effe-02 Direct-to-Streamer (SFP Port)

  • Path: Internet Router -> Ethernet -> effe-02 -> SFP/Fibre -> Audio Streamer SFP Port.

  • This directly targets modern high-end streamers like the Eversolo T series.

Configuration 3: Single Unit effe-03 Direct-to-Streamer (SFP Port)

  • Path: Internet Router -> Ethernet -> effe-03 -> SFP/Fibre -> Audio Streamer SFP Port.

  • Two additional low-noise and low-jitter Ethernet ports for other audio/video streamers/TV. Ideal for other devices in your system that only have copper Ethernet ports.

  • This directly targets modern high-end streamers like the Eversolo T series.

Configuration 4: Long-Distance Fibre Link (2 × effe-02)

  • Path: Internet Router -> Ethernet -> effe-02 -> SFP/Fibre -> effe-02 -> Audio Streamer Ethernet Port.

  • Fibre cable to bridge two effe units together over long distances, achieving 100% galvanic isolation between the noisy network and streamer.

  • This directly targets modern high-end streamers without SFP port.

Configuration 5: Multi-Device Streaming Hub (Ethernet-to-Fibre, Fibre-to-Ethernet Isolator)

  • Path: Internet Router -> Ethernet -> effe-02 -> SFP/Fibre -> effe-03 -> Three Streamer Ethernet Ports.

  • Fibre cable to bridge two effe units together over long distances, achieving 100% galvanic isolation between the noisy network and streamer. effe-03 provides three isolated, low-noise, low-jitter ports.

  • This directly targets modern high-end streamers without SFP port.

REVIEWS

iiWi youtube review

The Effe-01 creates a fully optical Ethernet link between your network and audio system, providing galvanic isolation to help prevent unwanted electrical noise from reaching your streamer. Reviewers have described its effect as a cleaner, more transparent presentation—reducing haze and muddiness while preserving the music’s natural tonal character.
