Question:medium

Compared to single-mode fibers, multimode fibers have

Show Hint

Comparison of optical fibers: \[ \boxed{ \begin{aligned} \text{Single-mode} &\rightarrow \text{Small core, high bandwidth} \text{Multimode} &\rightarrow \text{Large core, higher modal dispersion} \end{aligned} } \]

View Solution

Match List-I with List-II:

List-I (Modulation Schemes)	List-II (Wave Expressions)
(A) Amplitude Modulation	(I) \( x(t) = A\cos(\omega_c t + k m(t)) \)
(B) Phase Modulation	(II) \( x(t) = A\cos(\omega_c t + k \int m(t)dt) \)
(C) Frequency Modulation	(III) \( x(t) = A + m(t)\cos(\omega_c t) \)
(D) DSB-SC Modulation	(IV) \( x(t) = m(t)\cos(\omega_c t) \)
