You’re correct in your understanding of the Telegärtner Opt Bridge 1000M. To clarify:
The Telegärtner Opt Bridge 1000M is indeed an optical isolator that performs copper-to-optical-to-copper conversion. It allows for electrical isolation between components in an audio or network system by converting the electrical signal (copper) into an optical signal, which is then reconverted into copper again at the output. This isolation helps to reduce noise, electromagnetic interference (EMI), and ground loop issues, which can degrade audio performance, especially in high-end systems.
As you noted, this can be thought of as a type of optical Ethernet filter. However, the Telegartner unit uses active conversion, which means it’s leveraging electronics to perform the copper-to-fiber and back process, rather than relying purely on passive elements.
This active conversion allows the Telegärtner Opt Bridge 1000M to offer very high quality and precision in the signal transfer, ensuring minimal loss or degradation in the audio signal while providing the electrical isolation that helps with cleaner sound in high-end audio systems. It’s essentially a high-end, purpose-built solution for isolating and optimizing Ethernet signals for audio.
I am hoping this would be my last upgrade as far optimizing streaming to nth degree with the addition of Hypsos Dual Output power supply :-)
