研究目的
Investigating the fabrication and characterization of a dispersion-shifted fiber with a depressed cladding for minimizing dispersion in the 1550 nm wavelength range to enhance high-speed data transmission in optical communication systems.
研究成果
The fabricated DSF with a depressed cladding exhibits low dispersion and attenuation in the 1550 nm wavelength range, making it suitable for long-haul optical communication systems. Future work could explore scalability of the fabrication process and performance in other wavelength bands.
研究不足
The study is limited to the C-band wavelength range and does not explore the fiber's performance in other wavelength bands. Additionally, the fabrication process may not be scalable for mass production without further optimization.
