Question 11

What are the 5 parts of a fiber cable?

Answer 11

Core, cladding, buffet, strengthener, outer jacket

Question 12

What is the difference between single mode and multimode fiber?

Answer 12

Single mode fiber uses a laser to send signals over greater distances and is more expensive
Multimode uses a LED to send multiple signals at different angles across shorter distances and is cheaper
