980/1550 nm Coupler Fiber
Nufern 980C-HP fiber is a high-performance, mid-NA fiber optimized for use by coupler manufacturers in the telecom industry. It features low, consistent splice and bend loss, and a design to minimize excess loss in the coupler. The fiber is produced with extremely tight second mode cutoff tolerance, and the high tensile strength critical for long-term reliability in tight bend radius applications. These high-performance specifications also result in improved production yields and reduced component manufacturer costs.
7.7 ± 0.3 µm @ 1550 nm
Geometrical & Mechanical Specifications
Bend Loss: The bend loss for 100 turns @ LTBR (nominal) is 0.001 dB @ 980, by design.
Bend Radius: The bend radius for 0.05 dB/100 turns is much less than LTBR @ 980 nm, by design.
Coating Requirements: UV Cured, Dual Acrylate
