G.657.A2 Single Mode Fiber Optic
G.657.A2 optical fiber has a smaller bending radius than other types of single-mode fibers. Such as G652.D and G657.A1. Its minimum bending radius can reach 7.5mm,
Product Description
No.T-OF001-G.657.A2 TOEM’s bend insensitive type-A optical fiber complies with or exceeds the specification of ITU-T G.657 recommendation of type-A optical fiber. lt has all characteristics of TOEM’s low water peak fiber, and complies with the requirements suggested by ITU-T G.657A and the standard of lEC60793-2-50 B6 type optical fiber. lt is a bend-insensitive low water peak optical fiber with better macro-bend resistance performance.
