EXECUTIVE SUMMARY

The FiberHome AN5516-06 is a carrier-class, medium-capacity optical line terminal (OLT) engineered for central office deployments where large-capacity chassis would be underutilized. As a member of the AN5516 family, the -06 variant shares a unified software and service card ecosystem with higher-density siblings while occupying a compact 6U rack footprint with six service slots . This document provides a definitive technical reference for the AN5516-06, with particular emphasis on two architectural parameters that govern its deployment economics: backplane bus rate and achievable port densities. The platform supports a unified PON access model spanning EPON, GPON, 10G PON, and P2P, enabling operators to migrate from legacy PON technologies to next-generation 10G solutions within a single chassis .

HARDWARE ARCHITECTURE & SILICON

The AN5516-06 is built upon a modular, high-availability chassis architecture designed for carrier-grade service continuity. The backplane serves as the central interconnect fabric, and its rated capacity varies across documentation depending on the specific switching card configuration and measurement methodology. For the AN5516-06 platform, the backplane exchange capacity is commonly cited at 720 Gbit/s in comparative specification tables across the AN5516 series . Certain configuration-specific datasheets reference a backplane bus switching capacity of up to 3.76 Tbit/s when paired with advanced HSWD switch cards, though the base platform specification for the -06 variant aligns more conservatively with the 720 Gbit/s figure . The core switch card capacity, distinct from the backplane rating, is specified at 512 Gbit/s for the standard HSWA/HSWB control board configuration . This differentiation is critical for procurement evaluation: the backplane represents the theoretical maximum fabric capability, while the control board switching capacity defines the actual line-rate forwarding ceiling for deployed services.

The chassis accommodates two core switch card slots, six service card slots, two uplink card slots, and redundant power and fan units. All cards and PON optical modules support hot-swapping, and the system provides 1+1 redundancy for core control and switching modules . The control plane is managed by redundant main control boards, ensuring seamless failover in mission-critical access networks.

KEY FEATURES & ROUTING LOGIC
