Two 200+ Mbps Copper Technologies Available to Telcos

What telco with a copper-wire based broadband network wouldn’t love to be offering 200/100 Mbps down/up right now?

Cablecos’ DOCSIS broadband technology currently offers subscribers much faster speeds than the telcos’ xDSL copper wire speeds, which is helping cablecos take market share in the lucrative broadband market everywhere they compete against a telco’s copper wire networks. Many cablecos have begun increasing the speeds they offer to 100 Mbps and higher at no additional charge. Until recently, it appeared that telcos with copper wire networks had only these choices:

– Build all-fiber networks, a very expensive, disruptive and time consuming task but one that is certainly future proof.

– Deploy vectored VDSL2, which requires fiber to within about 200 meters of the residence, is available now and gets them into the 60 to 100 Mbps range, probably good enough for the “4K era” but not for the longer term.

– Quietly and over time exit the lucrative broadband service market as most of their subscribers switch to a cableco’s faster speeds — something that’s not likely.

– Wait until 2016/2017/2018 when they can start upgrading to G.fast networks that have gigabit potential. G.fast requires telcos to run fiber to within about 200 meters of the residence.

 

Vplus – filling gap between VDSL2 Vectoring and G.Fast

 

Telcos will soon have two copper wire broadband technologies that have the same physical architecture — fiber to within about 200 meters of the residence and the existing copper phone wires from there to inside the residence (no technician is needed to enter the residence):
Lantiq’s VDSL-based VINAX dp, which is available now
Alcatel-Lucent’s upcoming VDSL-based Vplus
G.fast from a number of chip and equipment makers with its 500 Mbps to 1 Gbps potential will be available in quantity in a year or so

There is a sizeable gap between the 80 to 100 Mbps capable vectored VDSL that’s shipping now and the 1 Gbps G.fast that’s coming in 2015/2016. The gaps exist in availability, speed and costs.

Chipmaker Lantiq and equipment maker Alcatel-Lucent have each developed technologies that cost less than G.fast to deploy and offer speeds of at least 200 Mbps…
