IEC 61753-1 random mating specified grade B (≤0.12dB mean, ≤0.25dB max for >97% of sample), meet large bandwidth and high speed requirements of the latest active optical equipment allowing large streams of data to be transmitted reliably over long distances. Corning bend insensitive fiber cable ensures less attenuation when bent or twisted compared with traditional fiber cables and this will make the installation and maintenance of the fiber optic cables more efficient. It also can save more space for your high density cabling.
