Telkom said that its network supports vectoring, but that this technology is currently not required for the data speeds offered in its high speed broadband pilot – hence up to 40Mbps.
VDSL vectoring is a technique for cancelling the electrical interference between adjacent VDSL circuits in the cable, thereby achieving a VDSL performance for individual circuits that is close to that of a single user in the cable.
Vectoring makes it possible to increase DSL speeds on existing copper broadband lines to up to 100Mbps.
Telkom said that although VDSL vectoring is supported by Telkom’s network, this technology is not required for the data speeds offered in the FTTx pilot, i.e. up to 40Mbps.
“The benefits of VDSL vectoring technology only become significant for data speeds above 40Mbps. Data speeds of up to 40Mbps can adequately be provided on standard VDSL technology, which is more cost effective that the VDSL vectoring technology,” Telkom said.
Telkom added that they will use vectoring to boost DSL speeds in future if there is a need for data speed applications above 40Mpbs.
