High Reliability:
• Provides highly reliable networking capabilities and ensures dual-OLT hot backup, remote disaster tolerance, and service
upgrades without interruption.
• Provides comprehensive Quality of Service (QoS) functions and supports traffic classification management, priority control,
and bandwidth control. The Hierarchical-Quality of Service (H-QoS) function meets various Service Level Agreement (SLA)
requirements of commercial customers.
• Provides an End-to-End (E2E) highly reliable design, enabling Bidirectional Forwarding Detection (BFD), Smart Link, Link
Aggregation Control Protocol (LACP) redundancy protection and GPON type B/type C line protection in the upstream direction.

Multi-Scenario Access:
• Supports access of multiple E1 private line services, and Native Time-Division Multiplexing (TDM) or Circuit Emulation Services
over Packet (CESoP)/ Structure-Agnostic TDM over Packet (SAToP) function.
• Supports the Emulated Local Area Network (ELAN) function and Virtual Local Area Network (VLAN)-based internal traffic
exchange, satisfying enterprise and community network application requirements.
• Supports non-convergence access of Internet Protocol television (IPTV) users. One subrack supports 8,000 multicast users and
4,000 multicast channels.

Smooth Evolution:
• Supports GPON, 10G Passive Optical Network (PON), and 40G PON on a platform, enabling smooth evolution and achieving
ultra-bandwidth access.
• Supports IPv4/IPv6 dual stacks and IPv6 multicast, enabling smooth evolution from IPv4 to IPv6.

Energy Saving:
• Uses special chips for conserving power. Specifically, 16 ports on a GPON board consume less than 73 W of power.
• Supports idle board automatic power-off and intelligent fan speed adjustment, effectively lowering idle board power
consumption.
