Question

Which of the following factors affect transmission rate in DSL?

(a) The gauge of the twisted-pair line

(b) Degree of electrical interfernece

(c) Shadow fading

(d) The gauge of the twisted-pair line and degree of electrical interference

I have been asked this question in homework.

The doubt is from Access Networks topic in section Computer Networks Introduction of Computer Network

Answer 1

Correct option is (d) The gauge of the twisted-pair line and degree of electrical interference

To explain I would say: Because DSL is made of twisted wire copper pair, the gauge of twisted pair line i.e. the protection and electrical interference would affect the transmission rate in DSL. Unlike DSL, FTTP is not really affected by these factors.
