The analysis software interprets the captured data and allows the user to trace all control frames. It estimates the network topology of ONT state machines, established data channels, exchanged configurations, E/R OMCI diagrams, analyses, and bandwidth graphs for each ONT, T-CONT and port with high precision and accuracy.

The GPD 10k7 is an incredibly powerful tool that includes a high-performance hardware capture card and a robust software application. With the ability to capture all upstream and downstream data simultaneously, it allows for the identification of PON status, entities, and their relations, as well as bandwidth allocation, consumption, and deviations from the standard. Its capture card hardware is designed with advanced optical modules and processing capabilities, allowing it to easily extract and decode Ethernet traffic from GEM ports, including TV and interactive applications.

Key Features

GPONDoctor 10K7 captures OMCI and OAM messages in real-time over the fiber to monitor negotiation processes and configurations. It displays the status of ONTs, GEM / XGEM ports, and T-CONTs in real-time. The software analyses data and presents it graphically for the analysis of PON installations. It identifies the offending devices and the cause of failure with precision and accuracy, making it an essential tool for troubleshooting and maintenance.

GPON Doctor can identify any issues in real-time by connecting to a fiber termination point within the PON network.

Evaluation rules

Evaluates and detects problems in XGS-GPON or GPON networks, detailing the offending devices and the cause of the failure.

GPON/XGSPON Captures in one click

The capture hardware features with state-of-the-art optical modules and high processing capacity. Capable of synchronizing with the downlink and uplink at any point in the network and calibrating itself automatically, allowing long duration captures.

Network topology

GPD 10K7 uses the captured data to deduce the network topology and applies a set of rules to certify whether the ITU-T G.9807.x or ITU-T G.984.x recommendation is met. It continuously updates the status of ONTs, XGEM ports, and T-CONTs while displaying the topology.

QoS assessment

It is possible to regenerate established services on a PON network and evaluate the QoS and QoE of services configured over a PON. For example, multicast video can be extracted and reassembled in real-time to be displayed on the GPONDoctor screen.

Diagrams

OMCI entity/relationship diagrams with alarms and errors, bandwidth allocation diagrams by ONT and T-CONT, and optional diagrams of the time evolution of bandwidth allocation.

Ethernet data traffic

External tools can effectively monitor and analyze user traffic in real-time through AES decryption by hardware.

New features

Optical Power Meter, Line Errors detection and reporting.

GPON-Doctor 10k7's Traffic Capture feature extracts and decodes FTTH traffic using ITU-T standards. It identifies the topology of ONT, OLT, and data channels, creating graphs that display the bandwidths of each channel.

With just one click

GPON Doctor identifies issues in real-time by connecting to a fiber termination point within the XGS-PON network.

Real-time XGS-PON Capture

The tool captures data from the fiber at a bit-level in both downstream and upstream directions, including OMCI and XGSTC/GTC messages, to facilitate the monitoring of negotiation processes and configurations. It provides real-time updates on the status of ONTs, XGEM ports, and T-CONTs, displaying the topology.

Diagrams

The OMCI entity/relationship diagram presents alarms and errors, along with bandwidth allocation diagrams for ONT and TCONT. Additionally, optional bandwidth allocation time evolution diagrams can be included.

Network topology

The network topology is determined by analyzing the captured data through XGS-PON control information, specifically OAM, PLOAM, OMCI, and DBA. This analysis provides a comprehensive understanding of the composition and status of network components, including the ONTs and the OLT.

QoS assessment

GPONDoctor 10k7 empowers users to regenerate services on an XGS-PON network. Specifically, it enables real-time extraction and reassembly of multicast video to display on the GPONDoctor screen. This feature is perfect for evaluating the quality of service (QoS) and quality of experience (QoE) of services configured over a PON.

The evaluation rules identify

Evaluation rules are applied to identify deviations from expected behavior regarding protocol conformity to ITU-T G.984.x, G.988, ITU-T G.987.2, G.989.3 standards.

PON & XGSPON analysis

Implementing multi-vendor ONUs will significantly reduce CAPEX. Any OLT can communicate with any ONT, regardless of the manufacturer. Addressing the concerns of FTTH networks is crucial:

Commercial use of various versions of the standard

ONUs and OLTs manufactured by different vendors may not be accepted

OMCI is complex and vendors may misinterpret the standard

The heterogeneity of IP service provisioning is also a reason for errors

FTTH acceptance

It is crucial to understand the fundamentals of PON networks as only a portion of the power arriving at an ONT results from the splitter. Keeping this attenuation in check is important to avoid failures during challenging conditions.

Test ensures the compliance

The procedure for implementing FTTH GPON and XGSPON networks utilizes passive optical components to divide the fibre stretch and create a tree-like topology. This results in a single point of origin and N destinations. These standards are outlined by the FSAN and detailed in the ITU-T G.9807.x/G.984.x/G.988.

Vendor Interoperability

The protocol test identifies errors in negotiation and transmission between devices caused by non-compliance with the standards. GPONDoctor 10K7 is necessary to identify interoperability deficiencies in cases of multi-vendor validation.

IP Services certification

The GPONDoctor, in combination with xGenius, a synthetic traffic generator, ensures the accurate transmission of IP services, including video and data, over the FTTH network. This functionality enables the emulation of IPTV channels, VoD flows, and real-time reproduction of voice streams to analyze QoS and QoE and identify the sources of degradation and failures with confidence.

Laboratory & Field Operation

Being portable, and rugged it is an ideal companion for FTTH problem identification in the field, concerning GPON protocol or IP service provisioning. It also serves as a potent tool for interoperability checking and conformance validation.
