Each <strong>fiber</strong> is 100% quality measured accordingto IEC 60793. Furthermore, the specific <strong>fiber</strong> is subject toperformance measurements with laser light sources to provideguaranteed link lengths at 1Gb/s transmission rates and DMDcontrol to support applications at 10Gb/s transmission rates.Patented ProcessOptical <strong>fiber</strong>s are manufactured by j-<strong>fiber</strong>'s patented, proprietarytechnology using a MCVD (Modified Chemical VapourDeposition) process. This technology allows us to flexiblyprovide innovative <strong>fiber</strong> designs according to the customer'sown specifications. Our improved patented process results inlow attenuation <strong>fiber</strong> with consistent geometric properties, highstrength, and precise control of each <strong>fiber</strong>'s index of refraction.The <strong>fiber</strong> has a high level of splice compatibility with optical<strong>fiber</strong>s manufactured by other processes.km1Special attenuation values available upon request
