Q2:Maximum distance and Maximum users?

  • Maximum range of 20 km, although the standard has been prepared to reach 60 km.
  • 64 users per optical fiber, although the system is prepared to support up to 128.

Q3:Regarding to the OAM issue, what benefits can your GPON solution offer?

  • High capacity packet switching with 32K MAC address table.
  • 4K VLAN and Q-in-Q
  • Ingress policing per service

Q5:What level of security do your GPON system support?
 FOT GPON solution can support protocol level security for the downlink due to the multicast nature of PON. Detail security features as following:

  2. MAC limit per port 
  3. Packet limit by type of traffic (Broadcast/Multicast/DLF) 
  4. MAC Flood Guard 
  5. Port Flood Guard 
  6. Packet Blocking by traffic type (Broadcast, Multicast, DLF) 
  7. Packet filtering (L1 –L4) 
  8. ACLs

  • In-band/ Out-of-band Ethernet telnet
  • SNMP for NMS

Alarm Function:

  • Critical, Major, Minor relay contacts
  • Management Interface: 1 Ethernet Port (NMS) and1 Console RS232 port (RJ45 type).
  • Upgrade: Remote s/w upgrade via TFTP/FTP/HTTP.

That’s why we are offering an “Excellent Operation and Management” to our customers and end users.
