The indisputable benefit of fiber for music


I've read a lot about fiber's audible superiority to Ethernet, and most of it I have taken with a grain of salt.  1GigE is plenty fast for just about anything, and it is balanced and galvanically isolated. The one area where fiber is clearly a better choice for music systems is lightning protection.

It is not uncommon for lightning to enter a home via the cable TV's coaxial cable. This can easily jump the millimeters from coax to Ethernet to Ethernet. So if you are like me, and rely on Ethernet cabling to stream to avoid any Wifi issues you are also creating a possible lightning path from the external Internet provider's connection all the way to your fancy audio gear.

In this one situation I have to say, the use of a 1m or longer fiber cable is the superior solution. I'm considering using this at the junction between the cable TV modem and my router, therefore isolating all of my streaming devices at once.

Best,

Erik

Eric, great subject, thanks. I’ve been thinking along the optic fibre solution, but without the clumsy add on converters. I’ll keep investigating and feed back. 🇦🇺
Just get an internet provider that uses fiber. I’ve been using 1G ATT fiber for years. So may benefits: 950Mb up and down speeds, quiet, low latency, cheap, and again, no noise.

In my case this would require a move. No can do. I’m lucky to get reasonable Internet speeds.

I would also recommend starting with a pair of TP-Link Gigabit SFP to RJ45 Fiber Media Converters as it is a relatively inexpensive tweak - it significantly improved my Roon experience (direct connection NAS => DAC).  I think there is a case to be made about galvanic isolation via transmission through optical fiber.  If you like the improvement then try swapping out the TP-Links with the Sonore opticalModule Deluxe (link:  http://www.sonore.us/opticalModule-Deluxe.html).  There is also a nice article in Absolute Sound that explains the whole process/setup for those that have an interest in streaming:

Good luck!

Most good power conditioners also have in/out ports for RG-6 cable and Ethernet...  consider using the available surge suppression in yours.

And if you don’t have one...  I mean...
