A pesar de que ya se han comentado brevemente algunas, en este apartado se consideran las ventajas y los inconvenientes principales de una red PON, terminando con una tabla resumen. Ventajas: Despliegue escalado de la solución: La estructura PON permite un ahorro en los equipos activos necesarios en cabecera en el despliegue inicial de la […]

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 […]
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. […]
FTTH/P network benchmarking in Slovenia
Market and regulatory overview In June 2011, Slovenia had a broadband penetration rate of 60.7% of households. There are three major broadband providers, led by Telekom Slovenije (TS) (42.7%), T-2 (18.9%) and Telemach (16.3%). Tus Telekom, Amis and other smaller broadband providers make up the remaining 22% market share At the end of September 2010, […]
FTTH/P network benchmarking in France
The French broadband market is dominated by the incumbent France Telecom (FT, 42.8% market share) and alternative DSL operators Iliad (Free) (21.8%) and SFR (22.8%). Numericable, the single cable operator, has a 4.2% share of the broadband market. Smaller operators, including Bouygues Telecom, share the remaining 7.3% of broadband subscribers. The three main operators – […]
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, […]
10G EPON optical transceivers drive FTTP applications
GPON and 10G EPON optical transceivers for fiber to the premise (FTTP) or FTTH Fiber to the home applications to its Passport line of universal transceivers. For GPON, SFP transceivers for both OLT (optical line terminal) and ONT/ONU (optical network terminal/Optical Network Unit) interfaces. there are also 10G EPON via both SFP+ and XFP transceivers; the SFP+ […]
Physical layer requirements of FTTH GPON Network
This section describe physical layer requirement for FTTH GPON network in three perspective, 1, Spectral Width,2. Attenuation Range, 3. ODN topology, etc. 1 Spectral width [ITU-T G.984.2] defines certain PMD specifications for the OLT and ONU. For a GPON system operating at 2488 Mbps downstream rate and 1244 Mbps upstream rate, the 20 dB spectral […]
