Maxim recommends using Rosenberger HSD connectors and Leoni Dacar 535-x cabling for STP/QTP links. The quality of the cable used is important in long distance data transmission. Shielded cabling provides better protection, immunity to common mode noise and return current cancelling in differential signaling. Use equalization in the Serializer, together with preemphasis in the Deserializer to create the most reliable link for a given cable.
•Foamed dielectric is preferred for weight and loss (Leoni Dacar 300, 302)
Advantages: Often cheaper
Note: Foam isn't applicable to STP since it is always sold dielectric.
•Sold dielectric is preferred for bending applications (Leoni Dacar 462)
Advantages: Door mirror replacement, blind spot monitor
•Double insulation is required for good performance
Advantages: Good for EMI/EMC interference
Good for smooth impedance vs. frequency
Aluminum shield is likely the first thing to break down
