This paper demonstrates the coexistence of next generation PON (NG-PON) systems with legacy PON systems for CHT's network by commercial coexistence element (CEx). Because there are GPON and EPON in CHT's network, we will show the impact to legacy PON systems by using this commercial CEx and how we modify it.
