Financial institutions are
known for their large networks and high demand for constant access to data.
Traditionally, if a bank wanted to inter-connect their multiple branch
locations, their options usually involved data transport mediums like such as
dial-up or T1 connections ranging in speeds from 56kps to 1.544Mbps. Compare
this to speeds of 10Mbps with an Ethernet network, let alone 100Mbps Fast
Ethernet or 1000Mbps Gigabit Ethernet, and you can see the benefit to one
all-inclusive Ethernet network. But how do you create an Ethernet network
which links multiple locations across long distances, when Ethernet is
defined by limits on transmission distance? Fiber optic cabling and in
particular, single-mode fiber, is the answer. Data traveling on twisted pair
cabling is required by Ethernet to regenerate is signal every 100 meters. But
on fiber, an Ethernet packet can travel up to 2000 meters on multimode, and
20, 40, 60, or even 80km on single-mode cable. These distances can be
beneficial to financial institutions in two basic applications. Lets look at a bank
example. This bank has a campus environment of several, multi-story buildings
making up its corporate headquarters. It also has several branch offices
located through out a metropolitan area.

Within the main building in their headquarters, the bank will want to create
a fiber backbone in the vertical risers between the floors. In the computer
room they would use media conversion to connect the fiber to a copper switch.
On each floor they would use a stand-alone converter to connect the fiber to
a copper switch servicing those users with twisted pair. The multimode fiber
backbone would provide two benefits. It would allow network data to travel
the potential long distances, up to 2km, required in high-rise office
buildings and due to fiber's high bandwidth capabilities, it provides future
proofing from tomorrows higher speed technologies. Fiber cable can be used to
connect the network from the main building to other buildings in a campus
environment. Creating a star topology will link each building in the campus
back to the main building by using fiber cable and media conversion. If the
two buildings are within 2km of each other, then multimode cable will work,
but if they are over 2km, then single-mode fiber must be used. Often these
longer distances play a role when the bank is connecting to branch office
locations and may require the bank to lease dark fiber from the local
telephone company or service provider. With either a local campus environment
or a metropolitan area network, the concept of media conversion remains the
same, providing connectivity between fiber cable and copper based networking
hardware. The bank has achieved
three goals in using fiber cable to make connections between different parts
of their network. First, fiber cable allowed them to create a Wide Area
Network with the feel and network speed of a Local Area Network. Second,
running fiber backbones in the buildings provides enough bandwidth to be
compatible with future technologies. Third, fiber cable provides them with
the security from high EMI environments and protection from wiretap's
listening and capturing sensitive data. Transition Networks is the
leader in media conversion technology; offering a wide array of products
including Ethernet, Fast Ethernet (FX and SX), Gigabit Ethernet, 10/100 rate
