Features of the RF-BLOK shielded design: Reduced interference from one piece EMI (Electromagnetic Interference)/RFI (Radio Frequency Interference) shield Increased insulation resistance up to 25% No soldering requirements as interconnect design needs no 360 degree soldering - eliminating the possibility of human error and/or cracking of the solder that causes grounding intermittence and the use of the most hazardous waste material - soldering flux Tight fit of internal wires as there is no inner mould No requirement of ferrite cores as signal loss and degradation are greatly reduced giving enhanced signal sharpness. Without the ferrite cores the cable is less stressed and more flexible Smaller overall dimensions which allows more room behind the host or peripheral Increased connector and mating strength - the 4 point reinforcement tabs on the RF-BLOK, attached to the connector, strengthens the pair as one
