BNC Connector Specs:
Canare offers a full line of high performance MIL-C-39012 true 75 ohm BNC connectors with impedance matched performance characteristics and specifications that properly address the latest generations of high bandwidth digital video equipment.
Importantly, Canare 75 ohm BNC connectors offer excellent mechanical pull strength and very low digital signal reflections; RL =/>26dB (VSWR =/<1.1) DC to 2GHz.
50 vs 75 ohm VSWR - Much of the 75 ohm video coax cable in use today may still be terminated with 50 ohm BNC connectors. Although this pairing is adequate for lower frequency bandwidths (such as standard NTSC broadcast transmissions), this mismatch will result in signal degradation and reduced picture quality at todays ultra high analog and digital video transmission rates.
