Smart Product Number: 460-HP
460 nm Select Cutoff Single-Mode Fiber
Nufern visible wavelength 460-HP fiber is optimized for use from 450 up to 600 nm. 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 tigher second mode cutoff tolerance than standard fibers, resulting in higher strength, increased component reliability, better production yields and reduced costs for component manufacturers.
