代码说明:

  Introduction Fiber-to-the-Premises solutions today vary from high-bandwidth, symmetrical and dedicated fiber Ethernet-to-the- Home (ETTH), to traditional TDM PON, such as Gigabit PON (GPON), solutions that are asymmetrical, share bandwidth among users and are not flexible nor scalable to address various residential requirements and enterprises in one infrastructure.
