Bend Insensitive Optical Fiber G657.A2

Product Description
Potevio Fasten's bend insensitive type-A optical fiber complies with or exceeds the specification of ITU-T G.657 recommendation of type-A optical fiber. It has all characteristics of Fasten's low water peak fiber, and complies with the requirements suggested by ITU-T G.657A and the standard of IEC60793-2-50 B6 type optical fiber. It is a bend-insensitive low water peak optical fiber with better macro-bend resistance performance.
