You are placing PTP fiber between two locations 55 km (34 miles) apart. You are told that DWDM equipment will be installed within the next 5 years. Which of the following optical fiber types should you use?
You are placing PTP fiber between two locations 55 km (34 miles) apart. You are told that DWDM equipment will be installed within the next 5 years. Which of the following optical fiber types should you use?
For placing PTP fiber with a future installation of DWDM (Dense Wavelength Division Multiplexing) equipment, non-zero dispersion shifted fiber (ITU-G655) is the most suitable choice. This type of fiber is designed to manage the dispersion effects that can degrade the performance of DWDM systems over long distances. It provides a balance between zero dispersion wavelengths and non-zero dispersion in other ranges, which is essential for the efficient transmission of multiple wavelengths in DWDM technology.
The answer: G.656 Wideband non-zero dispersion shifted pg.4-21
