FAQ
Q1: What voltage that MCR200-1T-1TW used?
A1: 5V DC, 2A
Q2: What is VDSL2?
A2: 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 enable operators and carrier to gradually,
flexibly, and cost efficiently upgrade exiting xDSL-infrastructure.
Q3: What is the best distance for MCR200-1T-1TW?
A3: In order to guarantee the stability and better quality of network, so we
would suggest the distance within 1.6 kilometer is the best for MCR200-1T-
1TW
Q4: What is the best date rate for MCR200-1T-1TW?
A4: We provide the data rate of the MCR200-1T-1TW is up to
100Mbps/55Mbps.
Q5: Is the MCR200-1T-1CX compatible with the MCR200-1T-1TW?
A5: Currently NO. Although the MCR200-1T-1CX (profile 12a) and the
MCR200-1T-1TW (profile 17a) are base on ITU-T G.993.2 VDSL2, but with
different Profiles, so far they are not compatible with each other.
Q6: What is SNR and what’s the effect?
A7: In analog and digital communications, Signal-to-Noise Ratio, often
written 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 better line quality, but lower
performance.
