Audio-Optimized SFP Optical Transceiver|1310nm Single-mode LC Duplex|For Hi-Res Streaming Systems

The SpeedyFiberTX Audio-Optimized Special-Spec SFP transceiver is purpose-built for high-fidelity streaming environments. Supporting 1Gbps transmission (1000BASE-LX/LH), it delivers exceptional stability and low interference for Hi-Res audio applications. Internally fine-tuned and constructed with components selected for audio use, it ensures clean, uninterrupted signal transmission between NAS, Roon Core, Lumin, and DAC systems—resulting in a quiet, interference-free audio background during long listening sessions.

This module is equipped with DOM (Digital Optical Monitoring) functionality, allowing real-time monitoring of optical power, voltage, and temperature—giving users greater control and reliability during extended streaming playback. Compatible with most SFP-ready switches on the market, it is an ideal solution for home HiFi networks, professional audio environments, and demanding users seeking clean and stable digital transmission in their audio systems.

✅ Recommended Devices & Compatibility Notes
For best results, pair with the SpeedyFiberTX Single-mode LC/UPC Fiber Patch Cable | Corning SMF-28 Ultra | Low Insertion Loss 0.1dB | Optimized for Hi-Res Audio Streaming (SMDXUDLCULCU2YNR). This combo has been field-tested in Hi-Fi setups to provide optimal signal integrity from NAS to DAC through audio-grade switches.

This module is compatible with most network switches equipped with SFP or SFP+ ports, and is ideal for high-resolution audio network setups—such as Roon Core, Lumin, audiophile-grade NAS, and DAC streaming systems. 


⚠️ Compatibility & Technical Specifications

  • Verify Interface Type: Please ensure your device has a dedicated SFP or SFP+ port. Note that certain models, such as Netgear GS105Ev2, GS108Ev3, and GS110TP (v1/v2), are RJ45-only and do not support fiber modules.

  • Broad Compatibility: This module follows MSA standards and is Cisco-compatible, supporting most open platforms like QNAP, MikroTik, TP-Link, and Netgear. Note: It is NOT compatible with ARISTA or INTEL switches.

  • ASUS Hardware Limitation: Most ASUS devices with SFP+ ports (such as RT-BE88U, RT-AX89X, etc.) are hard-locked to 10G and do not support 1G modules. If you are using an ASUS device, you must purchase a 10G SFP+ module to establish a link.
