630 nm Select Cutoff Single-Mode Fiber
Nufern visible wavelength fibers are optimized for use from 400 up to 900 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.
Geometrical & Mechanical Specifications
Bend Loss: The Bend Loss at 630 nm (100 turns at 13 mm radius) is <0.001 dB, by design.
Bend Radius: The Bend Radius for 0.05 dB/100 turns at 630 is much less than LTRB, by design.
Coating Requirements: UV Curable, Dual Acrylate.
