1.2 Ethernet over VDSL2 Bridge Description
PLANET's state-of-the-art Ethernet-over-VDSL2 products are
based on two core networking technologies: Ethernet and
VDSL2 (Very-high-data-rate Digital Subscriber Line 2).
This technology offers the absolutely fastest possible data
transmission speeds over existing copper telephone lines or
coaxial cables without the need for rewiring.
The VC-201A / VC-202A Ethernet Over VDSL2 Converter has
a switching architecture with RJ-45 10/100Mbps Ethernet port
and one asymmetric or symmetric Ethernet over VDSL port
(Asymmetric means upstream and downstream rates are not
the same while symmetric means upstream and downstream
rates are similar) – the VDSL port can be RJ-11 connector
(VC-201A) or BNC Connector (VC-202A). The VC-201A /
VC-202A can be set to Central Ofce (CO) or Customer
Premises Equipment (CPE) mode via a DIP switch. When
VC-201A-CO is connected with the other VC-201A-CPE device,
the performance will go up to 100/55Mbps for asymmetric
5
data rate within 200m and up to 25/4Mbps for asymmetric
data rate at 1.6km. The VC-202A (BNC) performance is up to
100/65Mbps for asymmetric data rate within 200m and up to
25/5Mbps for asymmetric data rate at 3.0km. This capability is
ideal for use as an Ethernet extender for your existing Ethernet
network.
PLANET VDSL2 Converter provides a much cheaper replacement
and smooth migration for existing Long Reach Ethernet (LRE)
networks.
The cable specications of the connection are listed as follows:
10Base-T, Category 3, 4 or 5 UTP
100Base-TX, Category 5, 5e or 6 UTP
Ethernet over VDSL2, twisted-pair telephone wires
Ethernet over VDSL2, coaxial cable
The two drawings are typical applications for the Ethernet over
VDSL2 Converter.
Slave device (CPE) must connect to Master device
(CO) through the telephone wire or coaxial cable.
Connecting Master to Master or Slave to Slave
Note
is not allowed. For the detailed definition of the
VC-201A / VC-202A to CO or CPE, please refer to
section 2.2.1.

xDSL broadband wire line communications.
Designed to support the wide deployment of Triple Play
services such as voice, data, high denition television
(HDTV) and interactive gaming, VDSL2 enables opera-
tors and carrier to gradually, exibly, and cost-efciently
upgrade the exiting xDSL-infrastructure.
Q3: What is the best distance for the VC-201A and VC-202A?
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 the VC-201A and 3.0 kilometer for
the VC-202A.
Q4: What are the best data rates for the VC-201A and VC-202A?
A4: The data rates of the VC-201A and VC-202A are up to
100Mbps/55Mbps and up to 100Mbps/65Mbps (downstream / upstream) in 200 meters, respectively.
Q5: Is the VC-201 compatible with the VC-201A?
A5: Currently no. Although the VC-201 (prole 12a) and
the VC-201A (prole 17a) are based on ITU-T G.993.2
VDSL2, but with different proles, so far, they are not
compatible with each other.

Q6: Is the VC-202 compatible with the VC-202A?
A6: Currently no. Although the VC-202 (prole 12a) and the
VC-202A (prole 17a) are based on ITU-T G.993.2 VDSL2,
but with different proles, so far, they are not compatible
with each other.
Q7: What is SNR and what’s the effect?
A7: 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 better line
quality, but lower performance.
Q8: What is band plan and what’s the effect?
A8: VDSL2 denes multiple band plans and conguration
modes (proles) to allow asymmetric and symmetric
services in the same binder (by designated frequency
bands) for the transmission of upstream and down-
stream signals. User has the ability to select xed band
plan. Symmetric is selected to provide better downstream
performance while asymmetric is selected to provide
better upstream performance.
