Overview

Welcome to our comprehensive FAQ for the FiberHome AN5516 series OLT. This guide addresses the most critical technical and procurement questions from B2B network engineers and IT managers. We cover everything from integration with third-party VoIP ONTs, throughput specifications, and CLI configuration to hardware redundancy and troubleshooting. As a carrier-grade, high-density platform supporting GPON, EPON, and 10G PON, the AN5516 is a versatile choice for FTTx, enterprise, and data center deployments .

Frequently Asked Questions

Q1: Can a FiberHome AN5516 OLT provision third-party VoIP ONTs?

Yes, the FiberHome AN5516 can provision third-party VoIP ONTs, but it requires specific configuration adjustments. The platform supports VoIP services, including SIP and H.248 protocols, for integrated voice and data delivery . To successfully provision third-party ONUs, you must configure appropriate ONT line profiles and service profiles. For example, when using UFiber ONUs, specific commands like set pon_interconnection_switch may be needed to ensure interoperability . While the AN5516 is optimized for FiberHome's own ONT series, it provides the necessary flexibility to support third-party devices with proper VLAN, QoS, and OMCI configuration for voice services .

Q2: What is the maximum switching throughput and backplane capacity of the AN5516-01?

The AN5516-01 offers a backplane exchange capacity of 3.2 Tbit/s and a control board switching capacity of 1920 Gbit/s. This high-throughput architecture supports Layer 2 and Layer 3 wire-speed forwarding . This level of performance enables the chassis to handle up to 256 GPON ports or 128 10G EPON ports, making it suitable for dense, high-traffic carrier and enterprise core networks .

Q3: What are the key hardware differences between the AN5516-01, -04, and -06 models?

The primary differences are physical size, slot count, and system capacity. The AN5516-01 is the largest with 16 service slots and a 3.2 Tbit/s backplane, designed for high-density central offices. The AN5516-06 is a medium-density 6U chassis with 6 service slots and a 720 Gbit/s backplane, while the AN5516-04 is the smallest, with 4 slots and a 1.5 Tbit/s backplane . All models support the same line cards, allowing for consistent software and hardware investment across different deployment scales .

Q4: How do I configure a basic voice service (VoIP) on the AN5516 via CLI?

Basic VoIP configuration involves creating VLANs, configuring GE uplinks, and binding service profiles to the ONT. First, use vlan 200 to create a voice VLAN. Then, assign this VLAN to the uplink port using interface ge 0/0 and vlan mode 1-3 access . The service is provisioned by creating an ont-lineprofile that maps the voice service to a specific GEM port (e.g., gem mapping 2 1 vlan 200) and a corresponding ont-srvprofile that enables POTS ports on the ONT .

Q5: What optical transceivers (SFPs) are compatible with the AN5516-01?

The AN5516-01 supports a wide range of standard SFP and SFP+ transceivers for GPON, EPON, and GE/10GE uplinks. For GPON, the system is typically used with Class B+ and Class C+ optical modules. For uplink ports, it supports GE optical, GE electrical, and 10GE optical interfaces (SFP+). It is critical to use modules that meet the IEEE and ITU-T standards for the specific line card being used, such as the GC8B (8-port GPON) or HU1A (5-port uplink) cards .

Q6: How do I troubleshoot a redundant power supply failover?

The AN5516 supports dual redundant power supply units (PSUs) with automatic failover. To troubleshoot, first check the LED indicators on both PSUs and the alarm log via the management interface. Ensure both PSUs are receiving power from separate, independent circuits to guarantee true redundancy . If a PSU fails, the system should switch seamlessly to the backup without service interruption. You can manually test the failover by simulating a power loss on the primary PSU while monitoring system logs .

Q7: Does the AN5516 support stacking interfaces for simplified management?

The AN5516 does not support standard Ethernet stacking; it is managed as individual chassis leveraging centralized management via the NMS. Redundancy and high availability are achieved through internal hardware redundancy (dual control boards, power supplies) and network-level protection protocols like RSTP and LACP on uplink interfaces . Multiple chassis can be managed centrally through FiberHome's network management system or standard SNMP.

Q8: What are the supported uplink interface options for high-speed backhaul?

The AN5516 offers flexible high-speed uplink options, primarily featuring 10GE and GE interfaces. Common uplink cards include the HU1A, which provides 1x10GE SFP+ port and 4xGE ports, and the GU6F, which provides 4xGE ports . The system supports a maximum of up to 16x16GE downlink interfaces, providing a robust backhaul architecture for high-bandwidth applications .
