Product Description
Potevio Fasten's bend insensitive type-B optical fiber complies with or exceeds the specification of ITU-T G.657 recommendation of type-B optical fiber. The fiber adopts the manufacture process of low water peak fiber with low attenuation at all wavelength (1260nm-1625nm). Compared with common single mode fiber, this fiber has better bend resistance. Under the windows of 1550nm, the appended attenuation of fibers with 7.5mm bend radius is less than 0.5dB, which can satisfy the special demand of bend capability of cables with smaller bend radius and optical components with small size.
