16 Pon Ports GPON OLT Customized for FTTH Access

Product Overview

HSGQ-G16L is a 1U cartridge-type GPON OLT designed for high-density FTTH, enterprise broadband, metropolitan area network, and rural broadband deployments.

The device provides 16 GPON interfaces, four GE Combo uplink interfaces, two 10G SFP+ uplink interfaces, one console port, and one ETH management port. Each GPON port supports a maximum 1:128 split ratio, allowing the complete device to support up to 2,048 GPON users under full configuration.

The OLT provides a 1.25 Gbps upstream/downstream rate for home broadband, enterprise broadband, voice, video, and other network services. It also supports CLI, Web, SNMP/NMS, and cloud management, allowing operators to configure, monitor, maintain, and upgrade the access network remotely.

With a transmission distance of up to 20 km on a single fiber, dual power supply options, dual link redundancy, and a space-saving 1U chassis, the HSGQ-G16L is suitable for distributed access networks that require high PON density and centralized maintenance.

HSGQ-G16L provides 16 GPON interfaces in a 1U chassis, allowing operators to organize subscribers into different buildings, floors, communities, service zones, or remote access areas.

The device supports different ONU types according to the network architecture and service requirements. ONU automatic identification, auto-discovery, auto-registration, authorization, and profile-based configuration can help simplify terminal provisioning.

For smaller FTTH projects, a 1-port GPON Mini OLT may be more suitable. The 16-port GPON OLT is designed for networks that need higher PON density and larger centralized access capacity.

Technical Parameter

16 GPON Ports with 10G Uplinks and Dual Power Backup

The HSGQ-G16L provides 16 GPON interfaces, four GE Combo uplink interfaces, and two 10G SFP+ uplink interfaces.

The GE Combo ports can be configured with electrical or optical modules according to the upstream network. The 10G SFP+ interfaces provide higher-capacity connections to aggregation switches, core switches, and metropolitan network equipment.

The product also supports dual power supply configurations. The standard configuration uses a single power supply, while selected configurations can provide power redundancy for projects that require higher service continuity.

Centralized Cloud Management for GPON Networks

The HSGQ-G16L supports CLI, Web, SNMP/NMS, and cloud management.

The cloud platform provides functions such as device lists, project management, version release, license management, permission management, user management, configuration, alarms, logs, firmware upgrades, Ping, and diagnostic functions.

Centralized management can help operators maintain multiple GPON OLTs across different buildings, communities, rural areas, and enterprise access sites.

Remote Alarm Notification and Equipment Control

The cloud management platform can receive alarm notifications and provide remote alarm information for network administrators and project engineers.

Remote maintenance functions may include equipment inspection, configuration, control, VLAN configuration, device restart, firmware management, and batch upgrade operations according to the selected software and hardware configuration.

These functions can help reduce repeated on-site maintenance and improve response efficiency when access equipment is deployed across multiple locations.

Efficient Heat Dissipation for 1U Installation

The HSGQ-G16L uses a 1U chassis with front-panel ports and dual fans that help form an airflow path through the equipment.

The cooling structure is suitable for continuous operation in network rooms, cabinets, and access equipment areas. During installation, sufficient ventilation space should be reserved, and the air inlet and outlet should not be blocked.

The 1U form factor also helps reduce cabinet occupation while allowing the device to provide 16 GPON interfaces and multiple uplink options.

Visual Monitoring of PON and Traffic Status

The visual management interface allows operators to review PON system status and traffic conditions from a centralized screen.

This can help technicians check link status, observe traffic changes, identify abnormal conditions, and support routine network maintenance.

Visual monitoring can be used together with logs, alarms, Ping, optical diagnosis, and other troubleshooting tools to improve visibility into the access network.

Layer 3 Switching for Network Expansion

The HSGQ-G16L supports Layer 3 functions such as DHCP, static routing, and OSPF. The product configuration also identifies support for RIP-related dynamic routing functions.

The Layer 3 switching capability allows the OLT to connect GPON access users with network service systems, telephone networks, upstream switches, and other Layer 3 resources.

Dynamic routing protocols can help support automatic route exchange and network expansion, while static routing can be used for fixed network paths.

Multi-Scenario FTTX Deployment

The HSGQ-G16L can be used in residential districts, commercial buildings, intelligent factories, hospitals, shopping malls, school campuses, high-speed monitoring networks, and enterprise clubhouses.

Different ONU types, split ratios, uplink interfaces, and service profiles can be selected according to the application scenario.

For small ISP deployments, the Small ISP Solution can be used as a reference for planning the OLT, ONU, uplink, and maintenance architecture.
