Fiber Feeder

With changing times, telecom remains a key market and fiber division continues to serve telecom products such as erbium-doped fiber, high index fiber, photosensitive fiber etc. This chain of fiber feeder will help in broadband revolution and enable telecom success when this industry turns round. Fiber feeder material is employed in high performance transmission pigtails, polarization- based modulators and other polarization-sensitive components.

Network engineering is never straightforward, especially when it involves composite optical links based on different types of fiber. But careful design and a detailed fiber feeder inventory can help carriers to cut the cost of operating and subsequently upgrading their infrastructure.The first single mode fiber feeder was installed in the early 1980’s and optimized to work with transmission systems. This fiber type, which is often referred to as standard single mode and continues to be deployed in some backbone and city, networks to this day. However in the mid 1990’s a new generation of single mode fiber appeared, coinciding with the development of the first commercial dense wavelength- division multiplexing systems?

Fiber feeder offers many advantages: their scalability, transparency and ease of deployment. Also, fiber feeder offers a non-blocking architecture that enables full-rate digital subscriber line to all subscribers. With no reliance on statistical multiplexing, they eliminate “last mile” bottlenecks that can happen in remote digital subscriber lines access-multiplexer deployments, ensuring full-rate bandwidth delivery is always provided to all customers.

By way of conclusion, it can be pointed out that while fiber to home or fiber close to the customer is envisioned by many as the preferred access technology of the future that is clearly a very long-term future. Some pioneering countries like South Korea are installing fiber close to the customer- within a fraction of kilometer via fiber-to the cabinet and using copper for the last several hundred meters. The truth is that for many millions of home and businesses, it will be decades before fiber feeder technology is available to even the majority of the world’ homes.

Fiber feeder architecture can be used to serve remote sites- an approach that effectively increases traditional uplink bandwidth and extends uplink reach. The bottom line is that fiber feeder plants are superior compared against a large number of copper loops deployed all the way to the central office. As such, they have the way for even greater broadband penetration.
