Sissejuhatuseks - kunagi, mingi aeg tagasi, mainisin, et on olemas uued teooriad, kuidas vaskkaablite kaudu suuremaid kiiruseid edastada. Ning peamiselt siis kohtadesse, kus pole võimalik olemasolevaid vaskkaableid välja vahetada valguskaablite vastu.

TeliaSonera Trials G.FAST- Fast Copper Access Solution from Huawei
[Stockholm, Sweden, February 18, 2014]: Huawei, a leading global information and communications technology (ICT) solutions provider, today announced that TeliaSonera , as the first network operator in the Nordics, have performed a field trial using Huawei G.fast copper broadband technology, at FTTH. The solution has been deployed in the TeliaSonera network in Helsinki, Finland with live customers and delivering real services. With this technology, TeliaSonera can provide up to 1Gbps bandwidth to customers connected by the legacy copper network, improving the customer experience of fixed network broadband services such as TV.

G.FAST technology is a faster version of DSL which can offer speeds of 1Gbps over a distance of up to 250 meters using copper - further on enhancing the capability and speed of rolling out ultra-high speed broadband connections to TeliaSonera' s customers together with continuous fiber deployments."

Huawei releases 300 Mb/s FTTD solution delivering superfast copper access
[Stockholm, Sweden, February 19, 2014]: Huawei, a leading global information and communications technology (ICT) solutions provider, today released a 300 Mb/s fiber-to-the-door (FTTD) solution. Through frequency band adjustment and encoding scheme optimization, the solution achieves a broadband access rate of up to 300 Mb/s over copper.

FTTD is favored by operators as a cost-effective and quick FTTx solution, due to its ability to reuse existing copper resources without requiring fiber infrastructure reconstruction to households. FTTD typically uses VDSL2 or vectoring technology to provide 100 Mb/s access over copper. However, with the emergence of the smart home, Internet of Things, and 4K/8K video services, there is an increasing demand from high-end subscribers for faster access rates.

Huawei's 300Mb/s FTTD solution can achieve up to 250 Mb/s downstream and 50 Mb/s upstream by increasing downstream frequency band offerings and employing a higher-efficiency encoding scheme which provides more reliable line quality. The significant enhancement in access speeds requires only a minor adaptation of O&M systems and software upgrades in customer premises equipment (CPE).
