These patchcords are made of Nufern 780-HP fibers for use from 780-980nm. The high-performance fibers were developed for applications such as RGB components requiring generation of couplers, diode pigtails and unique delivery needs. These fibers feature greater proof test levels and a tighter second mode cutoff tolerance than standard fibers, resulting in higher strength, increased component reliability, better production yields and reduces costs for component manufactures.
