1U cost effective 4PON gepon olt

Overview:
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.
