      • Home networking requirements  
      • GEPOF use cases
         –FTTH home networking applications
         –FTTH MDU applications
         –DOCSIS HFC home networking

       Home, Smart Home, Gigabit home… 
     • Advance of FTTH technology enables gigabit services to the 
        home
         – 10G EPON can provide 10 Gbps symmetric shared bandwidth
         – NG-PON2 can provide 40 Gbps aggregated capacities
     • Several service providers have announced providing Gigabit 
        services to residential and business customers 
     • Smart Home requires high bandwidth (data rate) connectivity 
        in home
         – Cloud, 4K video, multi-room DVR, high speed Internet, Internet of 
           things…
     • The current home network physical medium may become the 
        bottlenecks
