tailieunhanh - Migration to GPON – Practical Considerations from the Central Office to the Outside Plant

Gazing into the future may be possible for the few clairvoyants living among us, but building a telecommunication network based on psychic prediction would be like basing critical business decisions on a coin flip. Still, today’s telecommunication buzzword for any fiber-to-the-premise (FTTP) network is “future-proofing.” Without a crystal ball to examine future bandwidth needs and determine winning technologies, service providers face some major challenges in getting it right the first time | VIOLA Migration to GPON - Practical Considerations from the Central Office to the Outside Plant Migration to GPON - Practical Considerations from the Central Office to the Outside Plant Gazing into the future may be possible for the few clairvoyants living among us but building a telecommunication network based on psychic prediction would be like basing critical business decisions on a coin flip. Still today s telecommunication buzzword for any fiber-to-the-premise FTTP network is future-proofing. Without a crystal ball to examine future bandwidth needs and determine winning technologies service providers face some major challenges in getting it right the first time. With that in mind however there are plenty of considerations to examine closely when selecting an FTTP that will enable the flexibility of easy migration to next generation demand. This is particularly true of the passive optical network PON portion of the network. Practical considerations based on informed decision-making when designing flexible next-generation networks provide the foundation for a cost-effective transition between legacy and future access technologies. For FTTP networks the advent of Gigabit passive optical network GPON will confirm the need for network flexibility. Service providers need not to look too far in the past to find examples of networks built without consideration for future technologies. While our telecommunication forefathers may not have predicted today s broadband revolution as they designed the copper telephone network this legacy infrastructure still enabled a rough deployment of xDSL technologies. The unpredictable performance of xDSL over load coils splices varying gauges and conditions of the legacy copper network produced costly lessons in the importance of network flexibility. FTTP provides the opportunity for service providers to deploy new subscribers with a clean slate. Together they promise a new network built to provide today s services while adding the .
