Product Description



The OFSE3504 design chassis OLT device provides 4 EPON ports, 4*10/100/1000Mbps RJ45 ports and 4 uplink GE SFP ports.Its height is 1U, easy to install and save space. Each PON supports up to 1:64 spectral ratio, and the whole machine can support 256 ONU terminals under full configuration.

OFSE3504 uses advanced technology to support SLA and DBA to maintain the QoS characteristics of Ethernet.For commercial and network digital management, we provide a comprehensive, smart, strong, advanced and professional solution.

Implementation projects for "automatic allocation" and "power consumption information collection"
