With increasingly advanced and matured technologies in telecommunication network, Fiber to the Home (FTTH) has drawn much more attention of companies specialized in telecommunication nowadays. Generally, the FTTH broadband connections consist of two types of systems, known as Active Optical Networks (AON) and Passive Optical Networks (PON). And most of FTTH deployments are inclined to […]
Passive Optical Network
PON Fault Scenarios and Troubleshooting Basics
A PON network consists of an OLT connected via a PON splitter to multiple ONTs (one for each subscriber, up to 64 subscribers). Sometimes, a second splitter can be connected in cascade to the first splitter to dispatch services to buildings or residential areas, which has been introduced more clearly in the previous post “Understanding […]
Fundamental Test Methods for Passive Optical Components
Since the early years of fiber optics, there has been a need to passively switch, tap, split, and multiplex optical signals. Today’s technology allows designers to expand on these original tasks by also providing the ability to direct, control, and filter optical signals for more creative and cost-effective system designs using innovative passive devices. This […]
FTTH Access Network Based on GPON
Growing demand for high speed internet drives the new access technologies which enable experiencing true broadband. This leads telecommunication operators to seriously consider the high volume roll-out of optical fiber based access networks. In order to allow faster connections, the optical fiber gets closer and closer to the subscriber. Then FTTH (Fiber To The Home) […]
Introduction to PON Technologies
Passive optical network (PON) is a very significant class of fiber access system in the world and it enjoys a dominant position in the access market. GPON and EPON are the two classifications of PON. The primary differences between the GPON and EPON lie in the protocols used for upstream and downstream communications. This article […]
How to Deal With Technical Issues of WDM-PON?
From time to time, the needs for more bandwidth in fiber access networks have never decreased. And these demands such as file-sharing, TV services and high-definition videos have just increased the desire for broadband access network based on fiber. People may ask what will be the next fiber access technology. There is one technology which […]
