摘要
An optical fiber cable includes an unbuffered optical fiber, a tensile reinforcement member surrounding the unbuffered optical fiber, and a jacket surrounding the tensile reinforcement member. The jacket is suitable for outside plant environment. A water blocking material is placed between the unbuffered fiber and the jacket. The unbuffered optical fiber comprises an ultra bend-insensitive fiber that meets the requirements of ITU-T G.657.B3 and exhibits an additional loss of less than approximately 0.2 dB/turn when the fiber is wrapped around a 5 mm bend radius mandrel. The optical fiber cable also exhibits an additional loss of less than approximately 0.4 dB/km at 1550 nm when the cable is subjected to -20 °C outside plant environment.
