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.
