Three Main Factors Affecting FTTx Deployment

When operators weigh up their FTTx architecture options, a number of factors will have to be taken into account. These include what assumptions are made about customers’ bandwidth requirements; the topology of the existing legacy network; the level of competition from cable operators; the cost of laying fibre to the node compared with running it […]

FTTN architectures and performance

Overview A fibre-to-the-node (FTTN) architecture comprises a fibre-optic link between the central office and an intermediate distribution point. From this distribution point, the home and/or building is served with voice and data through either a wireline or wireless connection. If the existing copper plant is used for the ‘final drop’, which is usually the case […]

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 […]

TV and video services in FTTx triple play service

As telcos turn to triple-play services (video, voice and high-speed internet access) to reduce churn and increase revenue, they need to find a way of delivering TV and video to the end-user as cost-effectively as possible. Each of the major point-to multi point PON variants – BPON, GPON and EPON – offers two different methods […]


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 […]

Next-generation PONs

The FSAN consortium, through its Next Generation Access (NGA) task group, is exploring different technologies to evolve optical access systems beyond GPON. The two main candidates are 10G PONs and WDM-PONs. 10G PONs enable one wavelength to carry 10Gbps capacity, which is shared in the same way as existing point-to-multipoint PON architectures. WDM-PONs allow multiple […]

125Mbps to 2.5Gbps FTTx Burst-Mode Laser Driver/Postamplifier

The PHY2078 is a combined burst-mode laser driver and limiting amplifier for use within fiber optic modules for FTTx applications. Used with the PHY1095 or PHY1097 transimpedance amplifiers and a low cost serial EEPROM, the device forms a complete PON diplexer silicon solution. The transmit block includes a high-frequency modulator and a bias current generator. […]
