Key Features

The GPON Doctor OLT-e provides the same functionality as a GPON OLT. It is fully configurable and can emulate any commercial OLT behaviour by using different templates. This feature enables the replication of any Optical Line Terminations and the execution of advanced functionalities.

Benefits

• 802.1ad, 802.1Q and 802.1p
• Multiple OLT templates
• Implements DBA algorithm
• FEC coding both directions
• 128-bit AES encryption
• IGMP snooping supported
• Multicast filtering

OLT emulation

OLTe enables the replication of any commercial Optical Line Terminations and the execution of advanced functionalities:

• Receiving and reporting events, messages and alarms
• Programmed scripts at the OMCI level
• Generation of PLOAM messages
• Traffic management in GEM frames

Applications

GPON Doctor OLTe serves as an OLT, designed specifically for ONT/ONU interoperability testing. It is a reference tool for laboratory engineers involved in the planning phase of GPON networks and manufacturers of active GPON elements.

• GPON Protocol Mastering Tool
• ONU Conformance test
• Diagnosis and analysis
• ONU-OLT interoperability
• ONTs performance
• Protocol compliance

Laboratory Operation

A laboratory may require various configurations and testing methods, which cannot all be listed. However, here are some examples:

• Interoperability test to pinpoint errors
• Diagnosis and analysis of events and deviations

IP Services certification

The GPONDoctor combined with xGenius, a synthetic traffic generator, allows for a robust setup to verify the accurate transmission of IP services, whether video or data, over the FTTH network. This functionality permits 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

• Installation
• Troubleshooting
• Interoperability
• Analysis of protocols
• Protocol compliance
