48 PON ports and 4 10G uplink ports
  • Overview
  • Specification
  • Ordering Information
APL4000 High-density Modular OLT devices are the core part of passive optical network. APL4000 supports redundant EPON network, 10G network and content exchange. Any two ports can establish a self-recovery ring, meanwhile, APL4000 supports multiple independent self-recovery rings. Possible ring networks are: double optical fibers, single optical fiber, twisted-pair line, or any combination of 10G, Gigabit or megabit self-recovery rings. With hardware-based algorithm, the patented MRD-RING® (MRDcom Real-Time Ring) technology ensures less than 5ms self-recovery time of every node and less than 50ms self-recovery time of the network. All EPON ports can realize "1+1" all-fiber protection network with less than 50ms switching time. High backplane capacity ensures the rapid and effective network traffic exchange for multiple layers, the EPON ports can form large-scale and high-density redundant PON access applications. APL4000 series utilize FPGA and CPLD dynamic reconfiguration and replicate programming technology, support multiple redundancy mechanisms such as link aggregation and resilient connection for high stability and reliability, various key operating parameters can be monitored locally and remotely.
