As Gigabit Ethernet
moves out from the campus backbone and
toward the desktop, a higher capacity
Ethernet technology is needed at the
network core. In 2002, a new 10 Gigabit
Ethernet standard was ratified (IEEE
802.3ae) and today, 10 Gigabit Ethernet
switches, routers, and fiber optic cabling
are being deployed in carrier and enterprise
networks around the world. Like Gigabit
Ethernet , 10 Gigabit Ethernet has
a lower cost short reach option (10BASE-S)
designed with VCSEL’s to push
light signals further and faster down
multimode fiber, and long reach options
(10BASE-L) for greater distance using
single mode or multimode fiber with
a mode conditioning patch cord.
Since 10 Gigabit Ethernet is 10 times
faster than its predecessor, the distances
that can be achieved over traditional
multimode fiber are much shorter. The
distance limitations associated with
62.5 micron fiber (outlined below) have
accelerated the trend toward 50 micron,
and have demanded new, high bandwidth,
laser optimized fibers to be developed.
All components of the Fiber Connections
EasyLAN solution are available using
laser optimized fiber. Fiber Connections
offers pre-terminated trunk cables,
jumpers, and modules designed to meet
the 10 Gig distance requirements for
your network, all factory tested to
guarantee the IEEE 802.3ae standards
for attenuation and reflectance.
The Chart below outlines the available
multimode fiber types and the associated
guaranteed distance for 10BASE-S (850
nm VCSEL) and 10BASE-L (1310 nm laser).
