ITU-T G.655 recommends which type of singlemode optical fiber?

Question

Quizplus · Accepted Answer

ITU-T G.655 recommends NZ-DSF (Non-Zero Dispersion Shifted Fiber) as it has a low attenuation and better dispersion properties at 1550 nm wavelength, making it suitable for long-haul optical transmission applications. DSF (Dispersion Shifted Fiber) and SF (Standard Fiber) have higher attenuation and dispersion values, while N-DSF (Non-Zero Dispersion Shifted Fiber) has higher dispersion values at 1550 nm wavelength, making it unsuitable for long-haul applications.
