Ultra Low Loss OPGW

Suitable for ultra-long station distance non relay lines with long transmission distances, large transmission capacity, and low transmission losses.

(1)ULL fiber OPGW attenuation≤0.168dB/km, ULL+ fiber OPGW attenuation ≤ 0.164dB/km; (2)G. 654E fiber OPGW single reel and single core ≤ 0.165dB/km, 460km ultra long station distance without relay; (3)Solve the problem of ultra-long distance optical fiber transmission, can reduce the construction of optical communication relay stations, and passed the appraisal in 2012.
