Bending-loss Insensitive Single-mode Optical Fiber(G657A, G657B)

ZTT bending loss insensitive single mode optical fiber for access network has the properties of extended wavelength non-dispersion shifted single mode fibers and has bending resistance property with min. bending radius 7.5mm and 1 turn and bending loss<0.5dB.

ZTT bending loss insensitive single mode optical fiber adopts the UV curing technology; the coating material can be chosen; the fiber has single and double coating with easy stripping and small coating to meet different conditions.

Product  Details
  • ZTT bending loss insensitive single mode optical fiber adopts VAD+OVD or PCVD technology for perform drawing. When fiber splicing, the customer can customize different fiber with different methods according to the specified conditions to match the fiber splicing and reduce the splicing loss.
