2. XG2 Installation
XG2 is an equipment that administrator only has to plug fiber/cable and then it works, as easy as general Ethernet
switch without extra configuration. Hence, the most important things are not the operation of XG2. The configuration
of cabling, selections of physical media and applications in your environment is more important.
2.1. Choice 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, 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.
Connectors
10GBASE-T uses 650 MHz versions of the venerable IEC 60603-7 8P8C (RJ-45) connectors, that is already
widely used in Ethernet.
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.
Category of UTP network cable for reference
Cat 5
Provides performance of up to 100 MHz, and was frequently used on 100 Mbps Ethernet networks. May be
unsuitable for 1000BASE-T gigabit Ethernet.
Cat 5e
Provides performance of up to 100 MHz, and is frequently used for both 100 Mbit/s 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, double of category 6. It is suitable for 10GBASE-T. It works up to 100 m
(330 ft) for 10Gbps Ethernet. All the cables above does not have individually-shielded pairs as the picture below,
including Cat 6a.
