GPON-Doctor Analyzer

GPON Doctor is a passive Chipset-Less analyzer for GPON FTTH protocol. Its connected to a point on the fiber distribution of a GPON FTTH network and capture data at bit level in both upstream and downstream, performing all the control information at: OAM, PLOAM and OMCI. Fully interoperability-oriented analysis, it is ideal for operators in the deployment phase or GPON and GPON hardware integrators.

Capture+Analyze+Evaluate

GPON-Doctor is a fully autonomous solution: Composed of a hardware board of data capture, a high performance chassis/equipment and software for analysis and evaluation of the data captured.

Based on our own implementation, the capture hardware includes last generation optical modules and great processing power. Capable of synchronizing with the Downstream and Upstream data flow of the GPON fiber and automatic calibration, it allows to do  captures of up to 30 minutes in length.

Certification of interoperability between manufacturers GPON

The Analysis Software interprets the captured data and allows the operator to inspect the control flow from the first to the last frame, selecting and filtering data following configurable criteria. It also analyzes the content of the control information inferring the topology and state of a GPON network: ONTs preset, data channels established, configuration exchanged, bandwidth analysis and graphics for each ONT by TCONT.

The GPON Protocol Evaluation System applies a set of contextualized, dynamic rules to test if the captured traffic complies with the ITU-T G.984.x protocol: Generating a final inform listing al protocol violations of possible sources of malfunction.

Windows XP Embedded

The GPON-Doctor analyzer is based on Windows XP Embedded, which allows to include (according to the needs of the client) tools for analysis and management for other service protocols used on the GPON network to be evaluated. Very intuitive and usable, with a very low learning curve that lets you start using it right from the start.

Application examples

GPON-Doctor analyzer can be used in the following scenarios:

• Fundamental tool in the deployment of a GPON network.
• Diagnosis and analysis of incidents and malfunctions in an established GPON network.
• Troubleshooting GPON Interoperability between different manufacturers in a network operator.
• Assessment of compliance with the protocol in the development of GPON OLTs/ONTs.
• Analysis of GPON protocols from the Ethernet.
• Interoperability Test GPON 984.x.
• Refine your problems in a PON GPON.
• Knowing the state of the network and all its components (ONTs).
