With the transition to 4K or even 8K signals, the impedance of BNC connectors has become more important than ever.
According to Neutrik, every impedance has a negative influence on return loss and VSWR (Voltage Standing Wave Ratio), which are both important measurements ‘for reflected signals in a transmission line.’
It stated, “Especially on high data rates up to 24 Gb/s, as they occur when transmitting UHD signals, an impedance mismatch results in high return loss and thus bit errors are raising.”
The company’s rearTWIST UHD-BNC connector, which will be on show in the Excel, is a BNC connector, designed specifically for high frequencies. The insulator design, in combination with the reduced outer diameter of the gold plated centre pin, allows UHD data transmission within the required return loss limits.
