FTTH GPON : Class B+/C+, Distance Couplage à l’avenir

quelle est selon vous la tendance actuelle en matière de GPON au niveau distance, taux de couplage, classe de fibre Ou encore, les opérateurs misent-ils sur du GPON à base classB+ uniquement, ou entament-ils déjà le déploiement d’OLT compatibles class C+ car du coup, on peut imaginer des distances NRO-logement plus grandes selon la tendance, […]

The advantage of TWDM PON

With the completion of lab trials this year, commercial trials expected in 2015, and initial deployments forecast for 2016, TWDM PON (time wavelength division multiplexing passive optical networking) is on the horizon. While today’s PON meets the requirements of residential subscribers, small-tomedium-sized usinesses (SMBs), and some MBH (mobile backhaul) applications, CSPs (communications service providers) want […]

FTTH Network WHAT-IS

What is PON Passive optical networks

The PON architecture comprises an optical line terminal (OLT), based in the central office, and the optical networking terminal (ONT) – sometimes referred to as an optical network unit (ONU) – based on the customer premise. To connect the OLT and the ONT with data, a fibre-optic cable is used to carry a wavelength downstream. […]

Outside Plant (OSP) Design

The designer of the fiber network designs and digitizes fiber features using the standard G/Technology feature placement workflow and a fiber splicing editor. The end-to-end workflow is as follows. At a given location (central office, switching center), the user creates an ISP Connect feature. From this feature, the user places fiber cables, splices, remote terminals, […]
