Market Trend

It has been proven that FTTH has obvious advantages for the consumer due to the better performance than previous broadband services which delivered primarily over copper networks. The transmission capacity of fiber is almost unlimited and is unconditional compared to existing copper cabling systems. On the one hand fiber delivers the highest possible bandwidth of Internet access, both downstream (from the network to the end user) and upstream (from the user to the network). On the other hand fiber speed remains independent of the influence of distance from end-user to the network exchange – unlike the copper broadband family of technologies, whose speed reduces with distance, random noise, interference or crosstalk during signal transmission.

FTTH Network Description

A fiber to the home (FTTH) network constitutes a fiber-based access network, connecting a large number of end users to a central point known as an access node or point of presence (POP). Each POP will install the required transmission equipment to provide the applications and services over optical fiber to the subscriber. Each POP is served by a central metropolitan or urban fiber network, which connects all the access nodes throughout a large network or region. The two most widely used fiber network technologies are Passive Optical Networks (PONs) and Active Optical Networks (AONs). The network infrastructure for Passive Optical Networks (PONs) is a Point-to-Multipoint (PMP) medium sharing topology. The passive splitter multiplies the signal on the fiber optics into optical subscriber branches. Active Optical Networks (AONs) also known as Point-to-point (PTP) network infrastructure, a so called dedicated medium network which enable each dedicated end user direct connection to the POP by dedicated optical fiber. It is typically using Ethernet transmission technologies. The diagram shows FTTH network topology.

Benefits of Active Fiber Network

Hundreds of networks around the world and particularly in Europe – choose Active Fiber solution to deliver high-speed voice, data, and video services to single-family households and apartment complexes. By deploying P2P fiber structure, Active Fiber has an advantage in offering subscribers dedicated and flexible bandwidth of up to symmetric Upstream/Downstream 1Gbps performance. It is also important that Ethernet transmission technology is considered a matured and proven technology for carrying heavy network traffic steadily. It mitigates the risk of failure for the operators and helps to protect their investments. Additionally, the business model is also a key decision factor for fiber operators to design their fiber infrastructure. Active Fiber is also seen as a better method to support an open access services model, which fi t the requirements of most communities and utilities.

Open Access Network: In the context of telecommunications networks, “open access” typically means that multiple service providers are granted access to wholesale services in the local access network so they can reach the end customers without needing to deploy a new network. The most obvious business model for an open access network is full separation, but other models are also possible. Functional separation is another way to separate the ownership of the network from service provision. The reason why Ethernet is suitable for open access is all about VLAN technology, moving a subscriber from one provider to another is relatively flexible and straightforward. The Active Fiber infrastructure owner can easily wholesale fiber connection to other service providers. Below figure illustrates the typical Open Access Network.
