Abstract

As the optical access network expands, there is an increasing demand for optical fiber cables that improve the efficiency of Fiber-to-the-Home (FTTH) network installation and maintenance. To meet this demand, we have fabricated the single-mode hole-assisted fiber (SM-HAF) that satisfies low bending loss requirements of ITU-T G.657.A2 and B3 as well as other specifications of G.652. We have also developed an SM-HAF optical fiber connector, cord and cable, and confirmed their excellent bend insensitive characteristics.
