The Neutrik NBNC75BQP11X The transition to 4K or even 8K-signals made the impedance of BNC connectors more important than ever. Every deviate impedance has a negative influence on return loss and VSWR (Voltage Standing Wave Ratio) which are important measurements for reflected signals in a transmission line. Especially on high data rates up to 24 Gb/s, as they occur when transmitting ultra-high definition (UHD) signals, an impedance mismatch results in high return loss. Neutrik's new rearTWIST UHD-BNC connector is a specifically for high frequencies optimized BNC connector; based on the proven rearTWIST technology. The unique insulator design in combination with the reduced crimp diameter of the gold plated center pin allows UHD-data transmission within the required return loss limits.
