Ultraviolet Visible Wavelengths Fiber Preform G652D Preform for Bare Core Fiber Cable

A fiber preform is a cylindrical piece of specially manufactured glass that serves as the starting material for producing optical fibers. The term "G652D Preform for Bare Core Fiber" refers to a specific type of preform designed for manufacturing single-mode optical fibers compliant with the ITU-T G.652D standard.

The G.652D standard defines specifications for low-water-peak single-mode optical fibers used in telecommunications networks. These fibers are optimized for long-haul and metropolitan area networks, offering low attenuation, low chromatic dispersion, and improved performance in the wavelength range around 1310 nm.

The "Bare Core Fiber" part of the term indicates that the preform is intended for producing bare or uncoated optical fibers, which are typically used as the core material for further processing and coating to create finished optical fiber cables.

Key points about the Fiber Preform G652D Preform for Bare Core Fiber:

1. It is a preform specifically designed for manufacturing single-mode optical fibers conforming to the ITU-T G.652D standard.
2. The resulting optical fibers are optimized for long-distance and metropolitan area networks, with low attenuation and chromatic dispersion around the 1310 nm wavelength.
3. The "Bare Core Fiber" term implies that the preform is used to produce uncoated or bare optical fiber cores, which are later coated and cabled for various applications.
4. The preform is made of highly purified glass materials with carefully controlled composition and dimensions to meet the required specifications for the G.652D fiber standard.
5. Preforms are the starting point for the optical fiber drawing process, where the preform is heated and drawn into long, thin strands of optical fiber.
