Synchronous Optical Network or better known as SONET has existed for around two decades, no matter how the layout and development of SONET dates all the back to the early 1980's. It was introduced as a much needed update to the trustworthy T1 technology that was created in the early 1960's. Although T1 was ahead of its time in the 1960's, providing users the capability to transmit voice and eventually video and data traffic at speeds of 1.544Mbps, it was fast turning into a technology that had an update. T1 used a fundamental two cable copper connection which was limited in both distance and high quality of service because of interference. Much like T1, SONET was designed to be a fast, effective ways to transfer, multiplex, and switch digital signals for both voice and data to and from users' applications. As the communications world continued to enlarge and an increasing number of individuals were trying to transmit voice and data, copper wiring became less and less successful. It was becoming very costly to install and maintain copper backbones that consisted of hundreds if not thousands of cables. On top of the cost copper is also susceptible to electromagnetic interference (EMI), crosstalk and is limited in the distance data can travel over it. Any amount of electrical spike from a very simple thunderstorm or other cables which are too close to the copper lines would cause interference that could be felt on the receiving end. When fiber optics was introduced as a replacement for copper it resolved these issues, you could now send multiple streams of data over a thin glass core that wasn't effected by EMI. When fiber first appeared companies instantly begun to compete over who had the best most complex system to pass data over fiber optics. Although t.. .
