SNA8816T 16 Port Gepon OLT System Description:
The SNA8816T is a GEPON OLT system based on IEEE802.3ah Gigabit EPON standard. It comes with maximum 16 GEPON ports, which 
can connect up to 1024 GEPON ONUs at 1:64 Fiber Ratio. It is a Telecom Grade GEPON OLT system designed for ISPs offering high 
quality, high speed and high stability internet services( such as IPTV, VoIP and Data Transmission services) to Subscribers. 

Main Advantages:
Generally, a normal 16 port GEPON OLT supports only layer 2 access network features. But unlike the normal GEPON OLT, the SNA8816T 
supports rich Layer 2, 3, 4 network features which enables you apply it in Layer 2 access network and in Layer 3 aggregation network. 

Support ayer 2/3/4 network features, enables you apply it in Layer 2 access network and Layer 3 aggregation network. 
Support 1:64 Fiber Ratio at 20Km transmission distance, can connect up to 1024 remote ONUs.
Comes with plain PCBA design, fixing GEPON downlink ports and 1G uplink ports on board, saving installation space.
Support optional 10G uplink ports, enables ability of enlarging bandwidth by changing only Fiber SFP transceivers.
Support main power supply and backup power supply work in 1+1 mode, ensuring high stability of network.
Support DC Power supply, suitable for applying in ISPs'server room.
Support CLI command and OAM management, support OAM alarms of ONU failure events.
Support CTC2.0, 2.1 and 3.0 completely, enables high compatibility with ONUs from different brands.
Support Quick Network Recovery, Network resumes in less than 50ms in case of server and device reboots. 
Support SNMP V1, V2, V3, Telnet or NMS management, enables remote management, remote problem detects and remote problem solving of 
SNA8816T GEPON OLT and the registered ONUs.
