2. 10G SNR-CVT Series Installation
As a media convertor platform, installing 10G SNR-CVT series is very easy and simple: all you have to do
is to plug the proper fiber/UTP cables into 10G SNR-CVT series’ ports like a general Ethernet switch
without any extra configurations. However, selecting the proper physical media and applications in your
network environment is crucial when installing 10G SNR-CVT series. Please see the sections down below
for detailed information regarding to physical media types and 10G SNR-CVT series application.
2.1. Choices of UTP Cable and Optical fiber
2.1.1. 10GBASE-T (Copper Wire)
10GBASE-T, or IEEE 802.3an-2006, is a standard released in 2006 to provide 10 gigabit/second
connections over unshielded or shielded twisted pair cables and over distances up to 100 meters (330
ft). 10GBASE-T cable infrastructure can also be used for 1000BASE-T, allowing a gradual upgrade
from 1000BASE-T, and auto-negotiation to select which speed to use.
10GBASE-T Connectors
10GBASE-T uses 650 MHz versions of the venerable IEC 60603-7 8P8C (RJ-45) connectors, which is
already widely used in Ethernet.
10GBASE-T Cables
10GBASE-T works up to 55 m (180 ft) with existing Category 6 cabling. In order to allow deployment at
the usual 100 m (330 ft), the standard uses a new partitioned Category 6a cable specification, designed
to reduce crosstalk between UTP cables.
The table down below is a reference regarding to UTP cable categories.
UTP Cable Categories References
Cat 5 Provides performance of up to 100 MHz, and was frequently used on 100 Mbps Ethernet
networks. Cat 5 may not be suitable for 1000BASE-T gigabit Ethernet.
Cat 5e Provides performance of up to 100 MHz, and is frequently used for both 100 Mbps and
Gigabit Ethernet networks.
Cat 6 Provides performance of up to 250 MHz, more than double of category 5 and 5e. It works up
to 55 m (180 ft) for 10Gbps Ethernet.
Cat 6a Provides performance of up to 500 MHz. It is suitable for
10GBASE-T and works up to 100 m (330 ft) for 10Gbps
Ethernet. All the cables mentioned above do not have
individually- shielded pairs as the picture here, including
Cat 6a.
Cat 7 This standard specifies four individually-shielded pairs (STP) inside an overall shield.
Designed for transmission at frequencies up to 600 MHz. It has better performance than Cat
6a.

2.1.2. 10GBASE-R (Optical Fiber)
10GBASE-R is 10Gbps Ethernet connection that based on IEEE802.3ae. It uses fiber as transmission
media with different specification of fiber, connector and transceiver. 10G SNR-CVT uses two
standards, 10GBASE-LR and 10GBASE-SR.
10GBASE-SR
10GBASE-SR ("Short Range") uses 64B/66B encoding and 850 nm wavelength lasers. It is designed to
support short distances over deployed multi-mode fiber cabling, it has a range of between 26 meters
(85 ft) and 82 meters (270 ft) depending on cable type. It also supports 300 meters (980 ft) operation
over new, 50 μm 2000 MHz⋅km OM3 multi-mode fiber (MMF).
The transmitter can be implemented with a VCSEL (Vertical Cavity Surface Emitting Laser) which is low
cost and low power. MMF has the advantage of having lower cost connectors than SMF (single-mode
fiber) due to its wider core.
10GBASE-SR delivers the lowest cost, lowest power and smallest form factor optical modules.
10GBASE-LR
10GBASE-LR ("Long Range") is a Long Range Optical technology delivering serialized 10 gigabit
Ethernet over a laser with 1310 nm wavelength connection on single-mode fiber via IEEE 802.3 Clause
49 64B-66B Physical Coding Sub layer (PCS) using a line rate of 10.3125.
Single-mode optical cabling is used to interconnect transceivers at a distance spaced at 10 kilometers
(6.2 mi), but it can often reach distances of up to 25 kilometers (16 mi) with no data loss.
Fabry–Pйrot lasers are commonly used in 10GBASE-LR optical modules. Fabry–Pйrot lasers are more
expensive than VCSELs (mentioned above) but their high power and focused beam allow efficient
coupling into the small core of single mode fiber.
Fiber Specification
Fibers which support many propagation paths or transverse modes are called multi-mode fibers (MMF).
Fibers which can only support a single mode are called single-mode fibers (SMF). Multi-mode fibers
generally have a larger core diameter, and are used for short-distance communication links and for
applications where high power must be transmitted. Single-mode fibers are used for most
communication links longer than 200 meters.
Fiber Buffer/Jacket Color Meaning
Yellow Single-mode optical fiber, long distance connection
Orange Multi-mode optical fiber, short distance connection

2.2. Connection of UTP Cable and Optical fiber
2.2.1. 10GBASE-T (Copper Wire)
10GBASE-T uses the same RJ45 connector that is the same as original 100M/1000Mbps Ethernet
network. Just plugging the RJ45 connector into the port of 10Gbps and it is ready to work. hen
connected properly, the Link/ACT LED located under the RJ45 Port will be on accordingly.
2.2.2. 10GBASE-R (Optical Fiber)
Please see the figure down below for connecting the optical fiber, transceiver, and 10G SNR-CVT’s
SFP+ Port.
13

Optical Fiber
As mentioned above, there are Single-mode and Multi-mode optical fiber. Both of them can be used for
10G SNR-CVT series.
Fiber Connector
Optical fiber connector contains two ends of fibers and can attach
to SFP+ transceivers. There are two ports for one SFP+
transceiver: one fiber is for receiving and one fiber is for
transmitting. The picture here is called LC connector that can
attach to SFP+ transceiver.
Transceiver (Connector)
SFP+/XFP Transceivers can be plugged into 10G SNR-CVT’s SFP+/XFP
Ports. SFP+/XFP Transceivers are active components that consume power
from 10G SNR-CVT and are capable of converting signals between optical
data flow and electronic data flow.
For different transmission purpose, the component inside SFP+ form factor
can be 10BASE-LR or 10BAST-SR mode.

2.3. Applications Examples for Your Network
2.3.1. Application for University
10Gbps speed Ethernet connection may not be commonly seen in ordinary offices. However, network
administrators may have Gigabit Ethernet in their control rooms already. Getting 10Gbps Ethernet
connection from Internet Backbone and distributing it to different Gigabit Ethernet segment for different
buildings or organizations is practical and more cost-effective. Figure down below is an example of a
possible network structure for a university:
escriptions
AInternet backbone from ISP.
BThe distance from the central office to the university might be long, and it is advised to construct
the connection via single-mode optical fiber with 10BASE-LR mode, which can extend the distance
beyond tens of kilometers.
C10G SNR-CVT, which is located at the computer center of university.
After the conversions made by 10G SNR-CVT, expensive equipments for transmitting/receiving
network data via optical fiber are not required anymore.
EFull 10Gbps Ethernet switches may be exceeding your budget or not available. Some 1Gbps
switches reserve a swappable slot for future upgrading. You can purchase a 10Gbps module with
one 10Gbps port for these switches to serve the same purpose.
FSeveral 1Gbps connections can be distributed by the switches mentioned above to different
buildings inside the university by Cat 6a network cables (which can be extended to 100 meters).
G/H/I General switches with 1Gbps or 100Mbps ports can be connected here for the end-users.

2.3.2. Application for Online Game Company
For ISPs or online game companies, 10G SNR-CVT series provide a more economical solution for
control room cabling. ISP runs lots of customer's service such as e-mail servers, web servers or any co-
located network services in the control rooms. These equipments may not have the interface for the
connection of optical fibers. For online game company, administrators may have lots of online game
servers that need high-speed connections to Internet backbone in the control rooms as well. .

network data via optical fiber are not required anymore.
FDepending on the network loading requirements, Ethernet Switch with full 10Gbps ports or partial
10Gbps/1Gbps ports should be configured for data flow distributions.
GIf that the bandwidth requirement of co-located mail servers for some companies is not heavy, you can
connect them to 1Gbps port of 10Gbps switch as shown in the figure above.
HIf the bandwidth requirement of online game servers is heavy, you can connect them to 10Gbps port
of 10Gbps switch as shown in the figure above.
IDifferent kinds of server with different applications are located side by side by connections from
10Gbps Ethernet Switch via inexpensive Cat.6 cable.

2.3.3. Application for Home Users
The figure down below is an example of how the FTTX architectures may vary regarding to distances
between the optical fiber and the end-users. Fiber to the x (FTTX) is a generic term for any network
architecture that uses optical fiber to replace all or part of the usual copper local loop used for
telecommunications. These four technologies are listed down below:
Fiber to the node / neighborhood (FTTN)
Fiber to the curb (FTTC) / Fiber to the kerb
(FTTK)
Fiber to the building (FTTB)
Fiber to the home (FTTH)
The building on the left is the central office. The building on the right is one of the buildings served by
