Networks are increasing in their complexity, both in terms of cascaded filtering (e.g., via ROADMs in mesh networks) and multiple-bit/symbol modulation formats. For instance, intra-channel noise will increasingly be spectrally carved by filters, the signal bandwidths will frequently be as large as the effective channels widths, and different data rates will be used more and more on a given...

Will Bandwidth Growth Ever Stop? No. A number of different industry surveys indicate that total internet demand is growing at about 40% per year. This growth is driven mainly by increasing video traffic in the network—Netflix now takes up to 30% of the internet’s bandwidth at peak hours, and new competitors like Amazon, Hulu, Youku, and the BBC iPlayer are growing rapidly. This growth is now... Learn more

Having developed for twenty years, the digital subscriber line (DSL) technology has become the mainstream access technology in the telecommunications field. The DSL technology keeps developing to meet requirements for higher bandwidth, showing great marketing potential. The latest Vectored DSL technologies defined in the ITU-T Recommendation G 993.5 have the ability to cancel crosstalk between... Learn more
