VDSL1 vs VDSL2

Very-high-bit-rate digital subscriber line (VDSL or VHDSL) is a digital subscriber line (DSL) technology providing faster[vague] data transmission over a single flat untwisted or twisted pair of copper wires (up to 52 Mbit/s downstream and 16 Mbit/s upstream), and on coaxial cable (up to 85 Mbit/s down- and upstream); using the frequency band from 25 kHz to 12 MHz. These...

Opening the Door to In-Building Copper Network Upgrades

Many communication services providers have made the decision to deploy fiber-to-the-building (FTTB) networks to multi-dwelling-units (MDUs). This hybrid approach, in which the existing in-building copper network remains active, can be a cost-effective and viable approach for delivering the high-speed services subscribers demand while keeping costs in check. Yet, providers...
