Description

The 62.5/125 Radiation Hard Multimode Fiber is a specialized product from j-fiber’s series of radiation hard multimode fibers, meticulously engineered to endure the challenges posed by radiation-prone and harsh environments. This fiber is particularly suited for military and aerospace applications, where reliability and performance are critical. Its design ensures that it maintains low attenuation changes even under significant radiation exposure, making it a dependable choice for demanding conditions.

One of the standout aspects of this fiber is its compatibility with various cable constructions, including tight buffering and loose tube configurations. This is achieved through j-fiber’s standard double-layer acrylate coating, which not only enhances durability but also simplifies the cabling and installation process. Additionally, the fiber can withstand higher temperature ranges, thanks to the option of high-temperature acrylate or Polyimide coatings, further broadening its applicability in extreme environments.

Manufactured to meet rigorous standards such as IEC 60793-2-10, TIA/EIA 492, and ITU G651.1, the 62.5/125 Radiation Hard Multimode Fiber exemplifies j-fiber’s commitment to quality and performance. Its optical characteristics, including a numerical aperture of 0.275 ± 0.015 and effective group indices of refraction at 850nm and 1300nm, ensure optimal performance across a range of wavelengths. This fiber is not only a testament to advanced engineering but also a reliable solution for industries where precision and resilience are paramount.
