The correct answer is False. Non-zero-dispersion-shifted fiber (NZ-DSF) was introduced in the early 1980s. It is a type of optical fiber that has a small amount of positive dispersion, which means that the light waves travel slightly faster at longer wavelengths. This makes NZ-DSF useful for long-distance communications, as it can help to reduce the effects of dispersion, which can cause signal distortion.<\/p>\n
Zero-dispersion-shifted fiber (ZDS-F) was introduced in the late 1980s. It is a type of optical fiber that has zero dispersion at a specific wavelength. This makes ZDS-F useful for applications where dispersion must be very precisely controlled, such as in high-speed data transmission.<\/p>\n
Both NZ-DSF and ZDS-F are types of single-mode fiber, which means that they have a single core that light travels through. Single-mode fiber is more efficient than multi-mode fiber, which has multiple cores that light can travel through. This makes single-mode fiber the preferred type of fiber for long-distance communications.<\/p>\n
In conclusion, the correct answer to the question “Non-zero-dispersion-shifted fiber was introduced in the year 2000” is False. Non-zero-dispersion-shifted fiber was introduced in the early 1980s.<\/p>\n","protected":false},"excerpt":{"rendered":"
