In Barn: GigaFOILv4 – INLINE Ethernet filter

DJM GigaFOILv4 – INLINE Ethernet filter ($475.00).
The GigaFOILv4 – INLINE is the newest generation of the FOIL™ brand of Ethernet filters. Based on patented Fiber Optic Isolation Link (“FOIL”) technology, the GigaFOILv4 – INLINE utilizes fiber optics and specially designed circuitry to prevent 99.99999999% of electromagnetic interference (ie “Noise”) from passing through the filter.

The filter covers a frequency range of below 14kHz to beyond 18GHz and does not require a passband, meaning the only signal passing through the filter is the clean digital Ethernet signal.

DJM Electronics is the developer and manufacture of the FOIL™ brand of electromagnetic interference (“EMI”) filters. Founded in Southern California in 1978, DJM developed the FOIL™ technology in 2005 for industrial and military applications on RF shielded enclosures. The company was approached several times to develop a filter that did not require a shielded enclosure. The GigaFOILv4 – INLINE is the answer to those requests. With an insertion loss of 100dB from 14kHz to 18GHz, the GigaFOILv4 – INLINE is the most effective inline Ethernet filter available.

Will be interested in what you find. Currently using Dante Ethernet for file delivery.

I seem to recall that you were using TP-Link Fibre Optic devices to break the ethernet noise chain (as I do and I'm not sure but didn't you also try the PS Audio Network Bridge. If either/or it would be interesting to have your insight with any comparative listening.

There will be plenty of fibre in my review ;-)'s picture

Any updates Michael? Thanks.

he was fired (?). So I don't know if he'll be posting here in any capacity.
