As the use of data keeps on increasing rapidly, the world soon will be forced to shift to a new technology that has the ability to carry massive amounts of data effectively without any burden. A new generation of optical fiber, known as all-optical fiber, was introduced as the new backbone telecom infrastructure to meet growing bandwidth demands which will be a big challenge in the upcoming years. This technology promises an end-to-end optical connection between the end points, with no bottlenecks occurring due to electro-optic conversions. This paper studies the state of the art for all-optical network technology, by briefly describing the potential features and the benefits gained over other existed transmission mediums. The general approach of this work is all about specifically overviewing the fiber connection services in all-optical networks. It highlights the key components used in transition to fully optical network, including the unique all-optical cross-connects. Also, the most common forms of wave division multiplexing networks are reviewed as a multiplexing technique used to utilize the available bandwidth. However, a particular attention is devoted to the general conception of current and next-generation optical fiber networks in Libya in terms of energy efficiency. A huge power savings would be achieved via upgrading to all-optical network, which would influence positively on a countrywide level, mainly during the electricity outage crisis facing the national power system network along many years.
