Raising the Bar: Full Vectoring More Than Doubles Data Rates, Reach and Revenue Potential from Service Provider Networks

Low deployment costs and high bandwidth have allowed Fiber to the Node (FTTN) networks using traditional copper twisted pair for the last mile link to become the architecture of choice for delivering voice, video, and advanced data services to a bandwidth hungry world. This topology allows for the rapid deployment of lucrative triple play services at a fraction of the cost of an all fiber network. However, broadband equipment vendors must overcome the challenge of crosstalk in order to utilize copper to its fullest.

International Telecommunications Union (ITU) standard G.993.5 (G.vector) plays a critical role in cancelling crosstalk. And by doing so, the technology can drive throughput of 100 Mbps and beyond for next-generation FTTN networks. But to truly guarantee that performance level and fully utilize the bandwidth available, service providers must have systems capable of full vectoring, not the partial cancellation that has been discussed by some in the industry. Partial cancellation dramatically diminishes the value of vectoring and cuts network performance in half.
