GPD Cube

GPD Cube is a remotely deployable GPON/XGS-PON validation node that enables continuous, real-time analysis without requiring on-site engineers.

Why Cube?

Traditional GPON/XGS-PON troubleshooting often depends on portable instruments, expert engineers, and site visits. GPD Cube changes this approach by placing autonomous validation nodes directly in the network, allowing engineering teams to access, monitor, and troubleshoot remotely.

Traditional testing	GPD Cube
Engineer travels to site	Equipment is deployed in the network
Manual, point-in-time testing	Continuous validation
On-site expert required	Remote operation from NOC / lab
Limited availability	Always available
Reactive troubleshooting	Faster, proactive diagnostics
Cost per visit	Scalable operational model

GPD Cube helps operators reduce travel, accelerate troubleshooting, and improve visibility across GPON and XGS-PON infrastructures.

From analyzer to distributed validation

GPD Cube is designed for remote, autonomous operation in central offices, aggregation points, customer premises, laboratories, and field deployments.

Once installed, Cube can be accessed through 5G or IP connectivity, allowing engineers to perform diagnostics, extract traffic, validate services, and monitor network behavior without being physically present.

How it works

• Deploy Cube at any network point
• Connect via integrated 5G or Ethernet/IP
• Access remotely from NOC, engineering lab, or support center
• Capture GPON/XGS-PON traffic and validate services
• Generate data, reports, and operational evidence

This makes Cube suitable both for temporary troubleshooting campaigns and for persistent monitoring of critical network locations.

Autonomous validation node

GPD Cube integrates the key functions required to perform remote GPON/XGS-PON validation:

• Dual GPON / XGS-PON protocol analysis
• Integrated 5G connectivity
• Remote operation and control
• Real-time capture, background capture, and scheduled captures
• Multi-ONT access with integrated optical switching
• ONT power control for reset and recovery operations
• Remote access to connected ONTs
• Automatic capture upload and cloud integration
• Expert formats: CBIN, XML, CSV

The result is not simply remote access to an analyzer, but a deployable infrastructure element for continuous validation.

Multi-ONT validation without manual intervention

One of the key advantages of GPD Cube is its ability to work with multiple ONTs from a single deployed unit.

Integrated optical switching and ONT power control allow engineers to validate different endpoints remotely, without asking local staff to reconnect fibers, restart ONTs, or repeat manual procedures.

• Sequential validation of multiple ONTs
• Remote ONT reset and recovery
• Service provisioning verification
• Configuration consistency checks
• Faster comparison between ONT vendors or service profiles

Applications

GPD Cube can be deployed at multiple points in the access network, including OLT sites, aggregation locations, customer-edge environments, and interoperability laboratories.

• FTTH deployment validation
• Remote troubleshooting
• Remote audits
• Interoperability verification between OLT and ONT vendors
• Mass validation campaigns
• Continuous network monitoring
• Protocol compliance testing
• Service validation

Protocol-level visibility and analysis

GPD Cube captures upstream and downstream GPON/XGS-PON traffic and provides deep protocol interpretation from the subscriber perspective.

• PLOAM and OMCI message analysis
• Bandwidth map interpretation
• ONU / ONT discovery and operation analysis
• PON topology inference
• GEM port and service visibility
• QoS and service integrity analysis
• Optical power monitoring
• Detection and classification of protocol deviations

This gives engineering teams a clear view of network behavior, service activation, and interoperability issues.

Remote operation via integrated 5G

GPD Cube provides full remote access through native 5G and Ethernet connectivity.

• Remote desktop access without complex VPN or firewall configuration
• Automatic upload of captures, logs, and events
• Remote configuration and execution of test scenarios
• Centralized management of distributed units

This enables true “deploy and operate” workflows across multiple network locations.

Laboratory & field operation

GPD Cube is rugged and portable enough for field operation, while powerful enough to act as a persistent validation node in laboratory and operational networks.

• Interoperability labs
• Chipset validation
• Automated test plans
• Operator acceptance testing
• Field troubleshooting
• Remote engineering support

Unified platform

GPD Cube uses the same GPONDoctor software environment, reducing the learning curve for existing users.

• Dedicated GPON and XGS-PON applications
• Unified interface across GPONDoctor platforms
• Flexible licensing: GPON, XGS-PON, and optional features
• Support for offline desktop analysis
• Delivered with colorless splitters

GPD Cube: from field activity to distributed validation

GPD Cube transforms GPON/XGS-PON testing from a field activity into a distributed validation model. Instead of moving expert engineers across the network, operators can deploy Cube units where visibility is needed and operate them remotely, continuously, and at scale.
