Fibre
optic cable is a transmission medium favoured for
applications that need high bandwidth, long distances,
and complete immunity to electrical interference.
That makes it ideal for digital
signage, which requires high resolution and
transmission over long distances. Unlike network
platforms, fibre optic cable does not require
CPUs or special software at the display end.
All that is required is a transmitter and receiving
unit for each display. There are two options for
Fibre-optic cable: single mode or multi-mode. Single-mode
Fibre provides a higher transmission rate and up
to fifty times more distance than multimode, but
it also costs more. In general, the decision between
different types of fibre should be the result of
a simple cost-benefit evaluation: the distance and
level of resolution or performance required versus
the acceptable investment in distribution technology.
Benefits
& Drawbacks
Fibre
optic cable is optimal for transmitting high-resolution
multi-media over long distances, a feature which
makes it particularly appropriate for digital
signage. Fibre optic cable provides network-independent
performance without downtime or transmission lags.
It can transfer media over 40 kilometers or more.
In addition, it requires no special infrastructure,
software or display-side CPUs. However, Fibre
optic is a point-to-point technology - in other
words, a pure fibre optic cable solution will
not allow multiple displays to receive output
from a single video source. This can prove a significant
obstacle for multiple-display digital signage
installations such as malls and airports.
In
addition, fibre optic cable has a high price relative
to other technologies. Fibre optic cable's expense
can prove prohibitive when planning a large digital
signage project. A possible solution, discussed
below, is the combination of fibre optic cable
with other, less expensive solutions, allowing
the user to benefit from fibre optic cable's advantages
while reducing the total cost of the project.
