Ultra Low Loss and Large Effective Area Single-mode Optical Fiber(G.654.E)

ZTT low loss and large effective area of single mode optical fiber is designed for long distance transmission system, and manufactured with MCVD technique. On the basis of the precise control of the refractive index, the fiber has low attenuation at C and L wave band; meanwhile, increase the effective area to suppress the nonlinear effect, which allows larger incident power, increases the nonlinear tolerance of the transmission system to meet the requirements of long distance and high capacity transmission and provide more system redundancy.

Product  Details

ZTT low loss and large effective area of single mode optical fiber adopts the UV curing technology with double acrylic resin coating of insensitive bending loss which protects the fiber coating and reduces the bending loss introduced and meets different conditions. ZTT optical fiber adopts advanced coating curing technique to provide good dynamic fatigue resistance property and increase the service life of optical fibers.
