Broadband Internet — Very high rate Digital Subscriber Line
Information on Very high rate Digital Subscriber Line
Very high rate Digital Subscriber Line is
a DSL technology that allows broadband data services, including broadband
Internet access, to be carried a hybrid optic fibre/copper pair
telephone cable system. A Very high rate Digital Subscriber Line broadband system may
be symmetric or asymmetric&mdsash;it may provide the same speed on
uplink and downlink or it may provide a higher speed
on one. Very high rate Digital Subscriber Line is able to provide much
higher data rates than other forms of DSL because it
uses a combination of optic fibre and DSL technology, sometimes
refered to as "fibre to the kerb" (FTTC). Fibre to
the kerb (FTTC) involves deploying a fibre-optic cable to within
close proximity of the end-user and then transferring traffic to
individual copper pairs for the last segment to each individual
user.
Very high rate Digital Subscriber Line provides asymmetric speeds of 13 to 52
Mbps downstream and 1.5 to 2.3 Mbps upstream over a
single copper pair.
The cost for this high data rate is
a reduction in range to between 300m and 1.4 km.
