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
