Single-mode Optical Fiber G.657.A2

Single-mode optical fiber G.657.A2 combines excellent properties: excellent low macrobending sensitivity and low water peak level. It is fully optimized for use in the O-E-S-C-L band (1260 -1625 nm). The bend-insensitive characteristic not only guarantees L-band application, but also allows for easy installation without excessive care when storing the fiber, especially for FTTH network applications. The bend radius in the fiber guide port and the minimum bend radius in wall and corner installations can be reduced.
