Sounds like you need to fix the power supply to handle a direct attached drive, which uses milliamps.

Previously Corning ClearCurve single mode fiber was mentioned.
I got this link from computeraudiophile:
https://www.ebay.com/itm/2m-LC-LC-Duplex-9-125um-Corning-ClearCurve-Single-Mode-Bend-Insensitive-Fiber/232757309843?hash=item36316ab193:g:9~QAAOSwzFVa7Oco
Note: This is LC-LC duplex i.e. for use with a pair of SFP modules with one in an Ethernet switch with SFP, and the other one in Lumin X1.

Yeah, I got the cleancurve Single Mode Patch Cable from FOSCO. I think I found the perfect combo for my Clones Audio SG112-24 MOD with a pair of high quality transceivers. Still waiting for the Linear Solution LPSUs (even for the modem and NAS) to complete the picture. My comments to come.

The Clones Audio Cisco SG112-24 MOD is finally in place with the CleanCurve duplex in single mode bridging between both electrical circuits (modem/home theater circuit to my music dedicated circuit)
Better sound!
I would say the music is better defined and the attacks (the beginning of each note) are more detailed but softer at the same time. I would not say compressing, but "polishing". I think the reclocking has something to do with it.
Hope not to have confuse or lost somebody with this description.

HDMI optical cables have been an effective alternative to HDMI copper cables for a few years. However, what exactly is the difference between them? One thing hard to ignore is the difference of material under the coating, in which there is fiber for HDMI optical cable and copper for HDMI copper cable. Taking reference from the DAC and AOC, there are facts such as the transmission of fiber is faster and the signals on fiber are more reliable.

Based on reports from videophile forums, HDMI optical cables typically offer much better signal integrity over long distance (e.g. 10m) for projector setups. More importantly, most report these cables to bring improved video quality (likely due to electrical noise isolation). However, the HDMI optical converter embedded in the cables draw power from the devices they connect to, so occasionally certain models of such cables have compatibility issue with certain devices. Since conversion is involved, they absolutely do not work over their spec unlike good quality copper cables - if you buy a 10.2Gbps HDMI optical cable they definitely will not work at 4K/60p.
Two guys in our company also use HDMI optical cable (brand FIBBR) in their home projectors. In fact I'm planning to get one such cable from a cheaper brand and see if I can observe video quality improvement in my LCD TV setup. When buying such a cable, make sure it supports HDMI 2.0a 18Gbps.
Some readers here may not know that our company actually started as a professional video(phile) scaler manufacturer (this is why our staff e-mail address is pixelmagic.com). In the old days good deinterlacing and good upscaling of DVD to the native resolution of the projector brought a huge improvement. This is analogous to upsampling in music, but DVD upscaling brings a much more pronounced improvement on a big screen. We could also make 24p output from DVD, when 24p was not part of the DVD standard, and no DVD player in that era could provide that.
I need to connect an EdgeSwitch 8-150w up to a long MM fiber path (1 km). At that distance, I have to use 100mb fiber transceivers,
The question is whether the Edge switch hardware will support a 100mb SFP transceiver and run at 100mb?
The transceivers I have found are not on the compatibility list, but I didn't see any 100mb transceivers on the list so far.
BTW, you guys always take form amazon?
can i take this one: https://www.sfpcables.com/sfp-copper-transceiver-10gbase-t-cat-6a-7-20m

Quite unusual to have MM fiber run that distance. Why is your X1 1km away from the switch? The EdgeSwitch should support 100M SFPs but I would confirm with Ubiquiti.
The link you provide is for a 10G copper SFP with 30m distance.

SFP+ and 10GBASE are both NOT supported in Lumin X1, so the linked product will not work.
We only tested 1000BASE SFP.
We believe there is a chance 100BASE SFP may work, but we have not tested it and do not guarantee it.
Many thanks, so what is fit it?

We've tested several 1000BASE SFP: 850nm multi mode, 1310nm single mode and 1550nm single mode transceivers from fs.com and they work fine. The multi mode SFP we tested are limited to a distance of 550m I think. For 1km distance, consider 1000BASE 1310nm single mode.

10Gb/s is not compatible with Lumin X1.
This article introduces how the 10Gtek® 40Gbps QSFP+ BiDi transceiver reduces overall costs and installation time for customers when migrating data center aggregation links to 40Gbps connections.
In today's data center networks, most fiber cabling is built for 10Gbps connectivity. The problem we all face is how to migrate from 10Gbps to 40Gbps at low cost when the data center needs to upgrade. The 10Gbps cabling uses a two-core LC patch cord, while the 40Gbps cabling uses an 8-core MPO patch cord. So to support 40Gbps connectivity, data center architects are challenged by the need for a major upgrade of the cabling infrastructure, which can be too expensive or disruptive to allow data centers to quickly adopt and migrate to the 40Gbps technology.
10Gtek solves this problem with innovative 40Gbps Quad Small Form-Factor Pluggable (QSFP) bidirectional (BiDi) technology that allows reuse of existing 10-Gbps fiber infrastructure for 40Gbps connections. It greatly saves investment in fiber cabling and avoids waste of fiber resources.
[h=3]1. Troubles Confronting with Existing 40Gbps Transceivers[/h]Standard short reach (SR) 40Gbps transceiver is QSFP+ SR4. The SR4 transceiver is available in a QSFP form factor with separate transmitter and receiver. Each transceiver has four parallel fiber optic transmitters, plus four parallel fiber optic receivers, requiring eight fibers for signal transmission. The QSFP SR4 operates over an MPO 8-core fiber.
The figure below shows how the 40G QSFP+ transceiver works.
The connection between two 40G QSFP+ transceivers requires an MPO to MPO 8-core fiber patch cord. A problem arises when the data center network cabling is built for 10Gbps transmission. The 40G QSFP+ transceiver cannot directly use LC to LC fiber to transmit 40Gbps, and requires 8-core fiber patch cord, while the LC to LC patch cord is 2 cores. Due to this characteristics of the 40G QSFP+ transceiver, customers need to invest 4 times the cost of fiber to migrate their existing data center from 10Gbps to 40Gbps.
[h=3]2. 10Gtek 40G QSFP+ BiDi Transceiver Solution[/h]The 10Gtek QSFP+ Bidi transceiver can speed up the transmission rate from 10Gbps to 40Gbps through the dual-core multimode fiber connected to the LC interface. 10Gtek BiDi transceiver can achieve a transmission rate from 10Gbps to 40Gbps through a dual-core multimode fiber connected to the LC interface. In other words, the QSFP+ Bidi transceiver can realize 40Gbps transmission based on the existing 10Gbps optical fiber cabling without any extra investment in fiber. The following picture shows the 10Gtek 40Gb/s QSFP+ Bidi transceiver.
The 10Gtek QSFP BiDi transceiver has two 20-Gbps channels, each transmitted and received simultaneously over two wavelengths (850nm/890nm) on a single MMF strand. The result is an aggregated duplex 40-Gbps link over a MMF duplex LC-terminated fiber cable. The connection can reach 100 meters on OM3 MMF or 150 meters on OM4 MMF, which is the same as 40-Gbps SR4. It complies with the MSA standard.
The following figure shows how the 10Gtek 40G QSFP+ Bidi transceiver works.
[h=3]Conclusion[/h]The 10Gtek 40G QSFP+ Bidi technology solves the problem of fiber-optic cabling update from 10Gbps to 40Gbps in data center networks. Compared with other 40G QSFP+ transceivers, the 10Gtek 40G QSFP+ Bidi transceiver can save 4 times of fiber investment while meeting 40Gbps transmission rate, and can save a lot of labor costs. The 10Gtek QSFP+ Bidi transceiver can realize 40Gbps transmission on the existing 10Gbps cabling, and the transmission rate can be upgraded by a low investment.

If one believes in the benefit of audiophile clock in a network switch, beware that the clock module costs extra.
Whew! This is a lot to wade through so I thought I'd ask Peter Lie, Mike Boviard or anyone else who would like to help to distill this down if possible into what are the current thoughts regarding best practices for networking the X1.
I have an X1 inbound from the distributor in California to replace my S1. The S1 is currently connnected to the QNAP 879 music server via copper through an unmanaged Netgear 16 port POE switch mounted within a meter or so of where the X1 will reside. I would like to divorce myself of the copper connection to the QNAP in as efficient a manner as possible with and improvement in audio quality a prime metric.
I have the option of installing another network card in the QNAP NAS that has one or two SFP+ ports and possibly going directly to the X1 via the appropriate SFP+ modules and fiber. That seems to be the most direct but I am not sure how exactly the QNAP's new SFP+ ports would get their I.P. addresses from the ASUS RT-AC5300 router that I am currently using but it might be as simple as installing the card in the QNAP and doing a little bit of configuration in QTS.
The other option is to take one of the Ethernet ports that I am currently using, convert it to fiber via either a 4-port fiber switch or a media converter or something of that nature, and heading off to the X1 via the appropriate optical cabling.
I also realize there are very high end switches out there with OCXO or Femto oscillators and I may consider that in the future but not right now.
What is the current thinking about how to accomplish what I want to do?
Your thoughts are much appreciated!
Joe
