GAOTek 4 Ports Epon OLT

Description Overview GAOTek 4 ports epon OLT is a standalone 4-PON OLT, working with EPON ONU and ODN, to establish a passive optic network. It supports 4-PON, 128 ONUs access. It supports 6.21 mi to 12.43 mi transmission distance at the base of high bandwidth, full line speed L2 / L3 transition capacity. It supports SNMP and WEB management.   Features Supply 4 SFP PON ports, 4 Combo uplink ports, 4 10M/ 100M / 1000M RJ45 management port Support SNMP management and WEB management Each PON port support 1:32 split ratio total 128 ONUs access, maximum 256 Distance can reach 20km under 1:32 split ratio, maximum 1:64 Support IEEE802.3, IEEE802.3u, IEEE802.3ab, IEEE 802.1P QoS Support IEEE802.1Q VLAN 1U rack design, inside fan, better for heat dissipating Apply for town, village fibre network and surveillance   Technical Specifications Mac MAC Black Hole Port MAC Limit 16 K MAC address PON Features IEEE 802.3ah EPON China telecom or Unicom GEPON standard 12.43 mi (20 Km) for single fibber Access 64 terminals for single fibber PON Uplink and downlink triple churning encrypted function ONU terminal legitimacy certification, report illegal ONU registration DBA algorithm Standard OAM and extended OAM ONU batch software upgrade, fixed time upgrade, real time upgrade PON transmit and inspect receiving optical power Spanning Tree Protocol IEEE 802.1D Spanning Tree Protocol (STP) IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) IEEE 802.1s Multiple Spanning Tree Protocol instances (MSTP) ONU remote loop detecting alarm.

The system supports concurrent identification at most 50-service traffic Support packet filtration of L2 to L7 even deep to 80 bytes of IP packet head QOS Rate-limit to packet sending / receiving speed of port or self-defined flow and provide general flow monitor and two-speed tri-colour monitor of self-defined flow Priority remark to port or self-defined flow and provide 802.1P, DSCP priority and Remark CAR (Committed Access Rate), Traffic Shaping and flow statistics Packet mirror and redirection of interface and self-defined flow Super queue scheduler based on port and self-defined flow. Each port / flow supports 8 priority queues and scheduler of SP, WRR and SP WRR.
