Product Description

T-OF002-G.657.A1

The bend insensitive type-A1 optical fiber complies with or exceeds the specification of ITU-T G.657 recommendation of type-A1 optical fiber. It  complies with the requirements suggested by ITU-T G.652D and the standard of IEC60793-2-50 B1.3 type optical fiber. It is a bend-insensitive low water peak optical fiber with better macro-bend resistance performance.
