1.2 Introduction to Ethernet over VDSL2
Converter
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).
This technology offers the absolute fastest possible data
transmission speeds over existing copper telephone lines or
coaxial cables without the need for rewiring.
The VC-201/VC-202 Ethernet over VDSL2 converters has a
switching architecture with one RJ-45 10/100Mbps Ethernet
port and one symmetric Ethernet over VDSL port (symmetry
ꢀ
means upstream and downstream rate are the same or
similar) – the VDSL port can be RJ-11 connectors or BNC
connector. The VC-201/VC-202 can be set to CO mode or
CPE mode via a DIP switch. When the VC-20X-CO is used
to connect to the other VC-20X-CPE as a standalone pair, up
to 100/55Mbps asymmetric data rate within 200m and up
to 30/6Mbps asymmetric data rate at 1km. This capability
is ideal for use as an Ethernet extender for your existing
Ethernet network.
PLANET’s VDSL2 Converter solution provides
a
much
cheaper replacement and smooth migration for existing
Long Reach Ethernet (LRE) networks.
The cable specifications of the connection are listed as
following:
● 10BASE-T, Category 3, 4 or 5 UTP
● 100BASE-TX, Category 5 UTP
● Ethernet over VDSL, Twisted-pair telephone wires
● Ethernet over VDSL, Coaxial cable
The two drawings listed below are typical application for the
Ethernet over VDSL converter.
Slave device (CPE) must connect to Master
device (CO) through the telephone wire. Slave
cannot connect to Slave and Master cannot
connect to Master. To define the VC-201 to CO
or CPE, please refer to section 2.2.1 for more
detail.

mode, usually the CPE device will be located at branch
office, home or remote side as the long reach data re-
ceiver. The CPE can be connect to the PC, IP Camera or
Wireless Access Point and etc network devices.
● Fast and Interleave mode: (For CO Mode only)
▪ Fast mode guarantees a minimum end to end latency
less than 1 ms.
▪ Interleaved mode provides impulse noises protection for
any impulse noise with a duration less than 250 us. In-
terleaved mode has a maximum end to end latency of
10m sec.

● Rate Limit: (For CO Mode only)
User has the ability to select fixed data rate. When Rate
Limit is selected, the system will lock the date rate at
50Mbps/20Mbps whenever the calculated SNR margin is
higher than 9 dB. This gives best system stability.
● Target SNR (Signal Noise Ratio) Margin: (For CO Mode only)
When fixed SNR margin is selected, the system will
maintain the SNR margin at 9 dB across all usable loop
length.
Please power off the converter before making any
transmission mode adjustment.
VC-201 and VC-202 require 5V DC power input. It will
conform to the bundled AC adapter. Should you have the
problem to make the power connection, please contact your
local sales representative.

6. FAQ
Q1: What voltage that VC-201/VC-202 used?
A1: 5VDC, 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 opera-
tors and carrier to gradually, flexibly, and cost efficient-
ly upgrade exiting xDSL-infrastructure.
Q3: What is the best distance for VC-201?
A3: In order to guarantee the stability and better quality of
network, so we would suggest the distance in 1 kilome-
ter is the best for VC-201.
Q4: What is the best date rate for VC-201?
A4: We provide the data rate of the VC-201 is up to
55Mbps/100Mpbs (upstream / downstream) in 200 me-
ters.
Q5: Can VC-201 compatible with VC-102M / VC-102S?
A5: Our VC-201 is base on ITU-T G.993.2 VDSL2, and VC-
102M / VC-102S is VDSL1, so it can not compatible
with VC-201.
30
Q6: Can VC-201 compatible with VC-200M / VC-200S?
A6: Currently NO, although VC-201 and VC-200M/200S are
base on ITU-T G.993.2 VDSL2, but with different chip-
set specification, 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 SNR, is a measure of signal
strength relative to background noise. The ratio is usu-
ally 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 ter-
minal 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 iden-
tify and subsequently isolate and eliminate the source
of noise.
Generally speaking, the higher SNR value gets better
line quality, but lower performance.
