EXECUTIVE SUMMARY

The FiberHome AN5516-01 represents a flagship carrier-class Optical Line Terminal (OLT) platform engineered for the rigorous demands of next-generation telecommunications access networks. As a large-capacity, high-density multi-terabit platform, the AN5516-01 delivers unparalleled scalability and service versatility, designed to serve as the cornerstone for FTTx deployments in high-density urban, enterprise, and mobile backhaul environments.

This official technical overview details the hardware architecture, interface specifications, and operational capabilities of the AN5516-01, providing network architects and procurement engineers with the authoritative data required for deployment planning and infrastructure evaluation. The platform's unified architecture supports GPON, EPON, 10G PON (XG-PON/XGS-PON), and P2P access technologies on a common platform, ensuring seamless service evolution and maximum return on network investment.

HARDWARE ARCHITECTURE & SILICON

The AN5516-01 is built upon a 19-inch rack-mountable chassis featuring 16 universal service slots, enabling exceptional port density and configuration flexibility. The platform's backplane delivers a massive switching capacity of 3.2 Tbit/s, with control board switching capacity reaching 1920 Gbit/s, ensuring non-blocking line-rate forwarding across all populated slots.

The system employs high-performance, low-power silicon optimized for carrier-grade packet processing. At full capacity, a single chassis supports up to 256 GPON ports or 128 10G PON ports, translating to connectivity for over 16,000 subscribers at a standard 1:64 split ratio. The packet forwarding engine manages up to 288K MAC addresses and 128K IPv4/IPv6 routing entries, providing the table depth required for complex large-scale network topologies.
