Corning's HI 980 fiber features high numerical apertureand high core index of refraction.
It operates single mode at 980nm(2.5dB/km attenuation) and above and is suitable as component fiber for EDFAs, couplers, other DWDM components and pigtails for pµmp laser diodes.
This fiber enables efficient coupling and low bend loss within photonic products when used as component pigtails.
