BD-OLT-4000L is designed for chassis OLT device which provides 4 downlink GE- PON ports, 4 uplink GE SFP ports and 2 10/100/1000M RJ45 ports. The height is only 1U for easy installation and space saving. Each PON supports up to 64 terminals, the whole device supports up to 256 ONUs under full configuration. BD-OLT-4000L is applied for commercial and grid network digital management to provide perfect, smart, strong, advanced, professional solutions for “automatic distribution” and “electricity information collection” in the implemented project for the national grid.

Features：

Carrier-class stability and network resiliency

• Support PON fiber redundancy protection and device redundancy protection protocol
• Dual power supply input and power redundancy
• All PON and GE ports provide L2 full-line speed without losing packets

Full PON service

• Each PON support 1:64 splitting ratio ( The maximum quantity of 64 ONU)
• Hot plug PON fibber module design, the farthest 40Km transmission distance
• Support 128bits triple churning function to ensure the confidential for the data transmission
• Support dynamic bandwidth distribution DBA algorithm

Powerful OAM

• Use packet forwarding based on hardware to be effective for feature detection and packet filtering
• Support auto protection and user blocking for ARP attack based on MAC address
