FM8741C Key Benefits and Features

  • Cooperate with the FTTR sub-gateway, to achieve fiber to the roomand a true gigabit network in each room
  • The network side interface is XG-PON, and GPON/XGS-PON is optional to achieve ultra-broadband access for users.
  • The downlink port is a GPON port. Based on the application of  FTTR-H, it supports a maximum light split ratio of 1:16; based on the application of FTTR-B, it supports a maximum light split ratio of 1:64
  • The new generation of Wi-Fi 6 wireless technology, supporting 2X2 MIMO (2.4GHz&5GHz) and 160MHz bandwidth, can reach a physical air interface rate of 2976Mbps.
