Q1: What is VDSL2?
A1: VDSL2 (Very High-Bit-Rate Digital Subscriber Line 2), G.993.2 is
the newest and most advanced standard of xDSL broadband wire
line communications.
Designed to support the wide deployment of Triple Play services
such as voice, data, high definition television (HDTV) and
interactive gaming, VDSL2 enables operators and carrier to
gradually, flexibly, and cost efficiently upgrade the existing xDSL-
infrastructure.
Q2: What is SNR and what’s the effect?
A2: In analog and digital communications, Signal-to-Noise Ratio,
often written as SNR, is a measure of signal strength relative to
background noise. The ratio is usually measured in decibels (dB).
In digital communications, the SNR will probably cause a reduction
in data speed because of frequent errors that require the source
(transmitting) computer or terminal to resend some packets of
data. SNR measures the quality of a transmission channel over a
network channel. The greater the ratio, the easier it is to identify
and subsequently isolate and eliminate the source of noise.
Generally speaking, the higher SNR value gets, the better the line
quality gets, but performance is lower.
Q3: What is the best distance for IVC-234GT?
A3: In order to guarantee the stability and better quality of network,
we suggest the distance should not exceed 1.2 kilometers.
