LHY Audio SW-6 SFP 'Audiophile Ethernet Switch'
Previously, we discussed briefly on how an Ethernet Switch works. Have not read it yet? Here you go: link here
So, you ask: "Does the Audiophile Ethernet Switch really make a different?"
It may, or, it may not.
Our purpose in this conversation is not to analyze the sound quality. Evaluating sound quality is better suited for users and expert reviewers. Instead, our main focus is to offer valuable guidance on integrating Audiophile Ethernet Switches into a Hi-Fi System. We will also delve into technical elements such as SFP, Fiber Optic, Media Converter, and more.
In January 2023, we introduced the LHY Audio SW-10, which swiftly captured significant attention in the market among discerning audiophiles who are dedicated to enhancing their digital front-end experiences. LHY Audio SW-10 is high performance, exceptional built quality - Ethernet Switch with 8x RJ45 LAN Ports, 2x SFP Ports, 2x BNC Master Clock In/Out.
Simultaneously, we were inundated with multiple appeals for a switch that would bridge the gap between the SW-8 and SW-10 models. Collating and carefully considering this feedback, we embarked on an extensive development journey, resulting in the creation of the LHY Audio SW-6 SFP. This exceptional ethernet switch boasts a highly sought after SFP port, an isolated RJ45 port, and even houses an OCXO for enhanced precision.
Here are a few use cases for the LHY Audio SW-6 SFP Audiophile Ethernet Switch. These examples are intended to showcase various intriguing applications that could capture your interest.

Standard Home Network Setup with Audio Streamer (click to view more details)
In a typical scenario, a Home Network consists of the following key components:
Optical Network Terminal (ONT) or Modem provided by the Internet Service Provider (ISP)
Wireless Router responsible for directing the Internet service throughout the Home Network
Various devices linked to the network, such as laptops, desktops, and smartphones. These devices establish connections either through wireless Wi-Fi connections or physical Ethernet cables.
Additionally, the cherished audio equipment—Digital Audio Streamer(s)—forms an integral part of this network.
How to set up an Audiophile Ethernet Switch to the Home Network
An Audiophile Ethernet Switch can seamlessly integrate and coexist within the Home Network. To achieve this, first disconnect the link between the Home Network and the Streamer. Position the Audiophile Ethernet Switch in proximity to the Streamer and establish connections. Connect the Ethernet cables from both the Home Network and the Streamer to the Audiophile Switch.
The Audiophile Ethernet Switch functions as a 'switch,' distributing TCP/IP packets to all its ports whenever such traffic is present. When packets are intended for a specific connected device (identified by its IP/MAC address), the designated device, such as the Streamer, stores the packets in its buffer for subsequent internal processing.
Typically, these switches operate on a plug-and-play basis and usually don't necessitate configuration. There's often no distinction between 'Input' or 'Output' Ports; all ports operate uniformly, enabling bidirectional communication.
Wait, what about the ISOLATED PORT on the SW-6?
The Isolated Port showcases a custom-built Isolated RJ45 Port, offering seemless connectivity with specialized electrical noise isolation.
For enhanced performance, directly connect your streamer to this port.
If you need to connect multiple devices, you can link the Isolated Port to your router, and subsequently connect devices to the LAN1/2/3/4 ports.
The purpose of the isolated port is to effectively segregate noise from propagating between the two ends.
What about SFP? How can it be utilized?
For individuals adept in computer networking, SFP is a familiar term. It stands for Small Form-factor Pluggable, a compact electronic module designed to be inserted into the SFP port. This module transforms the SFP port into either an RJ45 LAN or a Fiber Optic (henceforth referred to as FO) connection.
Of particular interest is the FO aspect. The SFP FO Module comes in two standards: Single-Mode and Multi-Mode.
The LHY Audio SW-6 is equipped with 1x SFP Port. Utilizing an SFP FO Module, you can effectively convert the SW-6 into a Fiber Optic Ethernet Switch. This setup enables you to connect the SW-6 to devices equipped with SFP Ports (FO) using Fiber Optic connections.
Ethernet-to-Fiber Media Converter in conjunction with Audiophile Switch using Fiber Optic SFP
A plethora of RJ45/FO Media Converters is readily available in the market. These converters facilitate the transformation of RJ45 LAN connections into Fiber Optic ones, achieved through an SFP Port.
If you incorporate a Media Converter upstream in your Home Network, you can establish a connection to the SW-6 using Fiber Optic technology.
Here's where it gets intriguing: Fiber Optic transmission operates via light, ensuring a complete absence of electrical interference.
This characteristic effectively severs any electrical connection between the Home Network and the Audio Network. This distinct LAN within the SW-6 can aptly be referred to as the Isolated Audio Network.
This setup allows you to seamlessly link your Digital Audio Streamer(s) to the Isolated Audio Network.
Are there any traces of Electrical Noise present within such a network? The Electrical Noise remains contained within the confines of the Isolated Audio Network. This noise's intensity stems from the SW-6, boasting an ultra-low noise regulated DC output of under 5 microvolts, in addition to any noise contributed by the connected devices.
Noteworthy are the measurements from the Audio Precision Analyzer, showcasing the Regulated DC Output of the SW-6 at an impressively low level, measuring below 2.7 microvolts RMS.
Create a daisy chain connection between two Audiophile Switches, establishing a link through Fiber Optic connectivity.
Seeking an ultimate scenario? Consider the option of employing multiple SW-6 units within a premium high-end system (!).
Swap out the standard consumer-grade Media Converter with a SW-6. Connect the two SW-6s in a daisy chain configuration using Fiber Optic links.
Advantages:
The dual high-performance SW-6s effectively segregate the Home Network from the Audio Network.
Disadvantages:
This advanced setup comes with a notable higher cost ($).
Master Clock 10MHz Input
The SW-6 is equipped with a 10MHz clock input feature. It offers the capability to synchronize with the Master Clock of your system. In the following illustration, we'll synchronize the Clock Output of the SW-10 with the SW-6. Essentially, the SW-6 is capitalizing on the exceptional quality of the SW-10's OCXO.
We've explored nearly all conceivable scenarios for integrating the Audiophile Ethernet Switches, particularly the LHY Audio SW-6 SFP, into a Hi-Fi System.
