Description
Our DAC cables extremely low-insertion loss due to the unique foam skin, gas-injected dielectric technology as well as extreme control of balanced/unbalanced (Mode conversion). The technology offers ease of cable management and smaller packaging densities. The cable assemblies employ new, innovative PCB technology designed specifically to deliver signal integrity performance. The cables regulate cross talk and launch conditions between wire and PCB termination to optimize return loss and prevent or minimize “ringing” effects. Please contact us for more details.
• Compliant with SFF-8402 and SFF-8432
• Compatible to SFP+ MSA SFF-8431
• Lowest total system EMI solution
