By Steve Harris – For long-reach applications in the transport and access applications, cat A provides two sub-categories: A1 and A2. The G.657.A1 allows a 10 mm minimum design radius, while the G.657.A2 allows a 7.5 mm minimum design radius. These are both improvements over 15 mm to 30 mm in G.652.
