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

SFP-1G-LH Compatible 1000BASE-LX/LH SFP Transceiver Module (SMF, 1310nm, 550m/10km, LC)

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 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. We recommend the following tested models for optimal performance: Recommended Devices: • QNAP QSW Series – e.g. QSW-M2108-2C, QSW-M408-4C • MikroTik CRS Series – e.g. CRS112-8G-4S-IN, CRS326-24G-2S+RM • TP-Link Omada Series – e.g. TL-SG2218, TL-SX3008F • Netgear SFP-Compatible Models – e.g. MS510TX, GS110TUP, XS716T ⚠️ Important Notes: 1. Some common models such as Netgear GS105Ev2, GS108Ev3, and GS110TP (v1/v2) are RJ45-only and do not support SFP modules. Please confirm your switch has an SFP or SFP+ slot (SFP+ is backward-compatible with 1G SFP) before purchasing. 2. This module is built to MSA standards and is Cisco-compatible, and functions reliably on most open-platform switches, including QNAP, MikroTik, TP-Link, Netgear, and others. It is not limited to Cisco equipment.
