B. used for short transmission and graded index fibre
c. offer higher signal quality and graded index fibre
D. offer lower band width and step index fibre
​

Answer 1

Answer:

Option C is correct.

Answer 2

Answer:

The correct answer is option B,C,D

Explanation:

• A large diametral core in multimode fibre optic cable allows various modes of light to propagate.
• When a result, the number of light reflections formed as light travels through the core rises, allowing more data to flow through at the same time.
• The signal quality is decreased over long distances due to the high dispersion and attenuation rate of this type of fibre. In LANs, this application is often utilized for data and audio/video applications over short distances.
• Multimode fibre cannot transport RF broadband signals, such as those used by cable providers.
• Light in the perimeter can reach a receiver at nearly the same time as the sluggish but straight rays in the core axis due to the shorter journey and faster speed.
• As a result, there is less dispersion in digital pulse. Local-area networks benefit the most from this sort of fibre.
• This fibre is suitable for transmitting data across short distances.
