Ω, human body model, shown to be not damaging to its LI characteristics or its reliability; I-V curves may change in this ESD environment

7. Minimum bend radius of 30 mm is for long-term mechanical fiber reliability; however for 0.15 NA some optical loss may occur and a minimum bend radius of 45 mm is recommended for layouts with

multiple fiber coils.
