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.  
Note

▪ CO (Central Office) – the Master device mode, usually  
the CO device will be located at the data center of ISP  
or enterprise to link to the backbone.  
▪ CPE (customer premises equipment) – the Slave device  
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.  
1ꢀ  
 
● 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.

3. Installing and Using VDSL Converter  
3.1 Install the Ethernet Over VDSL2 Converter  
The Converter does not require any software configuration.  
Users can immediately use any feature of this product  
simply by attached the cables and plug power on. There is  
some key limitation on the Ethernet over VDSL2 converter.  
Please check the following items:  
● The device is used for Point-to-Point connection only  
(Master device to Slave device) and allows data and voice  
work on the same telephone or ISDN lines.  
● VC-201 Two RJ-11 connectors for VDSL port. One for  
voice device connection (like telephone) and the other  
one for network link connection.  
Depending on the quality of telephone line, the maximum  
distance of one VDSL segment is 1.5km (5000ft) with  
AWG 24 telephone wires.  
● VC-202 1 BNC connector and supports 50 ohm cable.  
Depending on the quality of coaxial cable, the maximum  
distance of one VDSL segment is 1.6km with 5C coaxial  
cable.  
● The distance will change by the quality of telephone wires  
and coaxial cables.  
3.1.1 VC-201 LAN to LAN connection  
Two sets of the converters could be used to link two local  
Area networks that are located in different place. Through  
the normal telephone line, it could setup a to 100/55Mbps  
1ꢂ  
 
asymmetric backbone, but one converter must be Master  
(CO mode) and the other one is Slave (CPE mode).

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, exibly, 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.
