GPON-Doctor™ 4000
Analysis and iden fica on in GPON Networks
Real‐ me user traffic extrac on
used for in‐depth analysis of GPON protocol conformance, interoperability evalua on, bandwidth assignments and field deployment troubleshoo ng. The results from the GPON Doctor™ analysis show:
GPON network topology: ONTs detected, ONTs and OLT opera onal status, data channels established,
En es created and the rela onship among them,
Bandwidth assignment graphics per ONT and TCONT,
Degree of standard conformance, by applying an evalua on smart engine, based on contextualized dynamic rules, against the ITU‐T G.984.x protocol .
Real me upper layer Ethernet traffic extrac on GPON‐Doctor™ 4000 allows clear‐text user traffic extrac on in real‐me for both upstream and downstream. The traffic is extracted at
Ethernet layer. This traffic can be further analysed by upper layer protocol analyzers, either external or by a so ware network protocol analyzer installed within the GPON Doctor™ 4000. The combina on of the GPON Doctor™ 4000 with a traffic generator and GPON OLT emulator, like GPON‐Doctor™ OLT‐e, is a powerful setup to verify the correct ONTs behaviour over a GPON network. This feature can be also used to regenerate services inside GPON Doctor™ 4000: Play Mul cast Video flows, hear sound of voice services in real me, analyze QoS & QoE.
Troubleshoo ng in PON and GPON networks With the aim of widening ONTs offer, it is important that any OLT interoperates with all available ONUs in the market. However, GPON has a number of intrinsic characteris cs that is currently making difficult to achieve the desired level of the interoperability:
Coexistence of products with different standard versions. Problems during the ac va on process.
Different ways of implemen ng the standards
OMCI, a very broad and with “vendor specific” op ons.
Heterogeneity among operators. Furthermore, the structure of a PON network is a fibre that is further divided using op cal power spli ers. The "degree of spli ng", is defined as the number of divisions that suffers the fibre to reach an ONT, which determine the percentage of op cal power arriving to an ONT. A enua on in a GPON circuit can be very high due to the sum of fibre spli ng, connectoriza on (Inser on loss), fusion splice, and distance in the fibre, and thus, some of the network ac ve elements operate under stress condi ons. In order to reach the op mum performance state of a GPON network , during the deployment and maintenance, all causes of interference need to be debugged by tools like GPONDoctor 4000. Non‐invasive Capture Once a Network is deployed, it is required that the usage of a test tool does not impact in its behaviour. Therefore, GPON‐Doctor™ 4000 transparently sniffs traffic within a FTTH network. Moreover, its automa c calibra on and stand alone configura on enables full capture of GPON network traffic without disturbing the communica on between the OLT and ONTs. The capture can be very long (e.g. 30 minutes) and allows captured data export to XML format for later analysis in desktop computers. Smart Network analysis and evalua on The smart analysis so ware interprets the captured data and translates it into a graphical and categorized format that can be easily
