Abstract

A flexible flat cable structure capable of improving crosstalk interference includes plural telecommunication signal conductors separated from one another and provided for transmitting differential signals, two support members installed on two lateral sides of the telecommunication signal conductor respectively, at least one filled material disposed between the telecommunication signal conductors. The ratio of the equivalent dielectric constant of the filled material to the equivalent dielectric constant of the support members falls within a range of 0.39˜0.27, and the ratio of the thickness of the filled material to the thickness of the support members falls within a range of 1.49˜1.37. Therefore, the flexible flat cable structure achieves the effects of reducing the time delay of the signal transmission of the flexible flat cable (FFC), suppressing the ringing noise of resonance, and improving the eye height of amplitude measurement, so as to suppress crosstalk interference and improve signal transmission quality effectively.
