High Quality for fiber optic equipment - Single-mode G657B3 super bending resistant optical fiber – GELD Detail:

● The minimum bending radius can reach 5mm, which is fully compatible with G.652.D fiber.

● Low attenuation, meeting the communication requirements of O-E-S-C-L band.

● Used in various optical cables including ribbon cables, it has extremely low bending additional loss.

● Accurate geometric parameters and large die field diameter ensure low welding loss and high welding efficiency.

● High dynamic fatigue parameters ensure the service life under ultra-small bending radius.
