Telnet Redes Inteligentes and Tecnalia present the first portable optical GPON networks analyzer of GPON: GPON-Doctor 4000
Telnet Redes Inteligentes and Tecnalia Corporación Tecnológica, presented at the 10th Interoperability Test Event of GPON (Gigabit Passive Optical Networks) organized by the FSAN in Tours (France, March 2010), the first portable GPON analyzer-evaluator of the market: GPON-Doctor 4000.
In early April 2010 was celebrated the 10th GPON Interoperability Test Event in Tours (France), organized by the FSAN (Full Service Access Network), the association whose mission is to create and share among manufacturers and operators the standards that define the latest generation of digital global communications.
During this international event, Telnet Redes Inteligentes and Tecnalia Corporación Tecnológica have presented a new product from the family of GPON (Gigabit Passive Optical Network) analyzers-evaluators: the GPON-Doctor 4000, the first portable GPON analyzer of the market. The analyzer participated in the event with great success both in monitoring the "blindfold pairings" (blind tests between equipment from different vendors where they should be able to communicate without problems on the first try) and in the task of evaluation and debugging during individual test sessions held between equipments from different manufacturers.
These interoperability sessions are necessary and very important in present and future high-speed communications; due to on they depends in optical fiber to the home networks that are being deployed around the world, to be able to use equipment from different manufacturers with absolute certainty that they are compatible, thus lowering deployment costs and maintenance. Among the possible solutions for residential fiber optic networks, GPON is the one that is being more integrated by telecom operators, given its low cost of deployment and maintenance.
However, the complexity of the GPON standard makes not all equipment manufacturers interpret it the same way, making it unable to connect to each other when placed on the same network. The great speed at which data travel down the fiber and the sensitivity of the optical medium itself makes it very difficult to monitor communications and find potential problems and responsibilities when something is not working in the network. Hence the great importance of GPON-Doctor analyzers that allow the evaluation of errors with a single click and automatically through a system of artificial intelligence and dynamic rules that evaluate each and every one of the elements of the network for GPON protocol failures.
With a small size, a weight of 3 kg and an autonomous battery, the new portable analyzer GPON-Doctor 4000 allows assessing the degree of compliance with the GPON standard by the network elements connected in a fully automated way. In addition, some more advanced features to analyze in detail the network communications, such as GPON control data capture in real time, automatic calibration, the graphical display of the diagram entities/relationships OMCI (ONT Management and Control Interface) and graphics bandwidth for ONTs (client computers on a network GPON) and TCONTs (containers of information on which traffic travels by fiber optics and are assigned to the ONTs to determine their bandwidth) allow an easy and intuitive analysis for both field trials in GPON networks deployments and for laboratory use in GPON development.
In addition, its ability to extract real-time customer traffic allows measuring the quality of services (QoS/QoE) given over the network to final clients: showing extracted video on the equipment’s screen, or monitoring the operation of IP voice services in real time.
The portable Doctor GPON-4000 complements the family of GPON analyzers with the laboratory equipment GPON-Doctor 8000, which has an OLT emulation module (central GPON equipment), which fully simulates the behavior of commercial OLTs in a totally configurable way. This functionality is primarily oriented to the development of GPON network equipment and interoperability certifications.
