Air Blown fiber optic is a cabling solution using glass fiber optic cables, blown through a ducting pipe. The main ducting pipe can have up to 19 micro ducts contained within it. A Coated “blow able” optical fiber is blown through a micro duct using compressed air. Carried by viscous drag, the fibers are lifted into the air stream and away from the wall of the micro duct, eliminating friction even around the tightest bends. One Fiber optic strand can carry 10 gigabytes of data every second or over 3000 telephone conversations.
Advantages to the consumers and companies providing these air blown fibers are:-
Installation in less than one day when the micro-ducts are installed
Ground work to install air blown fibers has to be done once
It’s a cost effective solution and requires simplified planning
BROADBAND ACCESS TECHNOLOGY: FTTH –FIBER TO THE HOME
Telecommunication carriers worldwide have come to the realization that their aging copper access infrastructure is being taxed as residential and business customers utilize ever-increasing, symmetrical bandwidth-intensive applications. The demands are being met by the deeper penetration of optical fiber in access networks and increasing deployment of fiber to the home (FTTH). As a result, FTTH is the fastest growing global broadband technology with significant deployments occurring in America.
Deployment of FTTH (fiber to the home) by the telecommunication companies in USA
FTTH (fiber to the home) is commonly deployed in two specific configurations. In the first one fiber is dedicated to each user in the access network, Point-to-point (P2P) network. While when fiber is shared (via a power splitter) amongst a set amount of users, typically 16-32, and is a passive optical network (PON). There are advantages and disadvantages to the deployment of P2P and PON networks based on financial, bandwidth and component considerations.
The ability to maximize the fiber count while maintaining a highly compact cable clearly saves space in the ducts without compromising capacity. Up to 192 fibers can be held within one Micronet cable, while Air Blown Fiber system employs a unique design that eliminates splices while maintaining high optical performance in the network.
