For many video system designers, deciding which ethernet cabling to use is a quick decision: go with the cheapest. However, this overlooks the possibility cable, and the video it carries, needs extra protection against common electromagnetic interference.
Is the difference between cable types that significant? In this note, we examine shielded cable, look at how it can prevent video problems, and compare it to nonshielded alternatives.
Inside this note, we explain:
- How Electrical Interference Affects Video Quality
- What Shielded Cable Looks Like Compared To UTP
- Physical Differences Between Cable Types
- Other Names For STP
- Typical STP vs UTP Costs
- Use STP Against Common Sources of Interference
- Practical Use Is Limited, But Axis Disagrees
