FTTx Link design using bend-insensitive fibers

Abstract

Given the tight power margins in Fiber to the Home (FTTH) network, one should carefully select fibers to overcome the macro-bending and staple losses which dominate especially at the consumer premises (CP). Bend-insensitive fibers (G.657 series) should be used in FTTH networks which gives network design architects more flexibility in system design, solves scalability issues in FTTH networks, and provides for a safety margin during deployment. This paper discuss the effect of macro bending and staple losses on the optical power margins of FTTH network and gives guide lines on fiber choices in each of the two fiber deployment scenarios — Multi Dwelling Units (MDUs) and Row Houses (RHs).
