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 (“EMI”) 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.
