| Because You Can't Dig It Every Year...  Life to cost ratio:
The cabling infrastructure is expected to last far longer
than software or hardware. A good cabling infrastructure will therefore need to
reflect a lot of vision regarding future applications and yet be cost effective.
Look at fiber's no-interference advantage: Fiber is completely
future-proof. It remains unaffected by EMI and RFI effects. Two core
tight-jacketed cables are normally used for these applications. Mostly
multi-mode 62.5u fiber goes in multi-storied buildings as a vertical backbone
and 50u laser graded or single-mode fiber goes as a horizontal backbone in the
big campus-wide projects.
Make it future-proof: In years to come, since the gigabit reaches to the
desktop, the necessity of 10-gigabit backbones will be a must thing for the
bandwidth-hungry applications. With the installation of 10-gigabit backbones,
companies will have the capability to begin providing gigabit Ethernet services
to workstations and, eventually, to the desktop in order to support applications
such as streaming video, high-end graphics etc. As the speed and bandwidth of
the network increases the distance that copper cable can support decreases. For
a long-term plan, it is best to use single-mode fiber since it will be a much
superior solution at a relatively much lower cost.
Share same resources: Real-time cabling management could be very effective in
the premises networking where different groups use the same backbones and share
the same resources. It's very essential to identify the various groups and
provide them the set up and bandwidth accordingly.
Sophisticated solutions: Cabling infrastructure is generally considered a 10
year investment as opposed to two or three years for electronics. For major
projects, sophisticated gigabit solutions are also available. Large enterprises
may find such solutions more suitable.
