Recommendation ITU-T G.9807.1 describes a 10-Gigabit-capable symmetric passive optical network (XGS-PON) system in an optical access network for residential, business, mobile backhaul and other applications. This system operates over a point-to-multipoint optical access infrastructure at the nominal data rate of 10 Gbit/s both in the downstream and the upstream directions. XGS-PON systems are able to […]

Ventajas e inconvenientes de una red PON
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 […]
Comparison of WiMax and FTTH
WiMAX stands for Worldwide Interoperability for Microwave Access. The industry trade group WiMAX ForumTM (http://www.wimaxforum.org ) has defined WiMAX as a “last mile” broadband wireless access (BWA) alternative to cable modem service, telephone company Digital Subscriber Line (DSL) or T1/E1 service. FTTH stands for Fiber to the Home, in america, operators name it as FTTP […]

FTTH Fiber to the Home FAQ
Q. What is FTTH fiber to the home ? A. FTTH (Fiber to the home) is the delivery of a communications signal via optical fiber from the operator’s central office all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires or coaxial cable. Fiber to the home is […]
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 […]
PLC Splitter summary
In 2012, a leading market and technology analysts announced the Asia Pacific region (APAC) region leads in the consumption of Planar Lightwave Circuit (PLC) splitter compact devices with 68% of the worldwide value, followed by the American region and finally the EMEA region. The increase of mass FTTx PON network deployment dominates the worldwide PLC […]
OSP Outside plant construction
Overview The deployment of a PON architecture requires a number of outside plant components, including the optical distribution frame, splitters, splicing closures, and wall-mounted boxes on the home or the building. It also requires fibre-optic cables with specific performance characteristics, both in the indoor and outdoor environment. The selection of cables and associated components, as well as how […]
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. […]
which is better AON or PON ? AON versus PON
AON advantages ■ Higher symmetrical bandwidth capability, which could become an even more significant advantage if demand for P2P and Web 2.0 applications increases rapidly (see 4.2.3). ■ Greater bandwidth scalability. The ability to swap Ethernet line cards in the central office to increase bandwidth capability makes AONs far more flexible than PONs. By virtue […]
