Key Features

High-Capacity Connectivity
- 4 GPON Ports: Each port supports up to 128 ONUs (Optical Network Units), enabling the OLT to manage 512 ONUs in full configuration.
- Symmetric/Asymmetric Rates: Compliant with ITU-T G.984 standards, offering 2.488 Gbps downstream and 1.244 Gbps upstream per PON port.
Advanced Traffic Management
- Dynamic Bandwidth Allocation (DBA): Prioritizes critical services (e.g., video streaming, online gaming) while optimizing bandwidth utilization.
- QoS Hierarchical Scheduling: Supports 8 priority queues per port, ensuring low-latency delivery for voice and video traffic.
- Multicast Optimization: Efficiently delivers IPTV and video-on-demand services via IGMP snooping and VLAN-aware multicast.
Scalable & Resilient Design
- Modular Uplinks: Equipped with 4x SFP+ slots (1G/10G) and 4x RJ45 Gigabit Ethernet ports for flexible backhaul options.
- Dual Power Supplies: Redundant AC/DC inputs with automatic failover, ensuring 99.999% uptime.
- 1U Rack-Mountable: Compact form factor (1U) with low power consumption (
Automated ONU Provisioning
- Zero-Touch Deployment: Auto-discovers, registers, and configures ONUs using serial numbers or MAC addresses.
- TR-069/SNMP Support: Integrates with cloud management platforms for remote monitoring, firmware updates, and diagnostics.
Enhanced Network Management
- VLAN & QoS Mapping: Segments traffic across 4094 VLANs and applies port-based QoS policies.
- Optical Link Diagnostics: Real-time monitoring of optical power, signal-to-noise ratio, and link status.
- High Split Ratio Support: Compatible with 1:128 Splitters, maximizing fiber utilization for FTTH deployments.
