- Details
JYD-808OLT is designed for chassis OLT device which provides 8 downlink 1000M PON ports, 4 uplink GE ports ,4 uplink 10GE ports by HOHI. The height is only 1U for easy installation and space saving. Each PON supports up to 64 terminals, the whole device supports up to 512 ONUs under full configuration. JYD-808OLT adopts advanced technology to support SLA and DBA to keep strong function on the Ethernet and QoS features. JYD-808OLT 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.
