| Why Fiber? |
POF(Plastic
Optic Fiber) is widely accepted in digital audio systems
e.g. AC-3 and DTS. Similar to glass fiber, plastic optical
fiber consists of a core surrounded by cladding. The refractive
index of the cladding is made smaller than the core to keep
incident light rays reflecting where the core and cladding
meet, and down the fiber. When a short pulse of light is
shown into the fiber, it can travel down the fiber in several
different pathways or "modes" depending on the
core diameter and the wavelength of the light pulse. The
way light is transmitted down the fiber and switched on and
off at different pulse rates is how data is communicated
or transferred through the optic.
Different from Glass fiber, Plastic Optical
Fiber requires less management extensive and less technical expertise.

The basic advantages of optical transmission are :
- Low Transmission loss : as a result to require less
electricity power to deliver the signals.
- No Emission : optical transmission is harmless to
health because the there is no magnetic field generated
by optical transmission.
- Long Distance : owing to the optical transmission
feature, there is very small distortion during data delivery
(POF at about 0.1dB/10m)
- High Data Rate : Glass fiber can easily reach 10Gb/sec
and POF standard is 15Mb/sec for audio data transmission(DVD
spec). The latest POF data rate is up to 100Mb/sec.

| POF Applications |
| There
are more and more modern electronic devices equipped with optical
output to reach a higher quality audio output. You can find
the optical output port at your DVD player, TV game console
(Playstation2, Xbox), Hi-Fi Amplifier, and a part of computer,
home theater, CD player and MD player….etc. |

| POF for Vehicles |
| A
major potential of Plastic Optical Fiber is in Car Industry.
Owing to the superior feature of none interference between
devices by optical data transmission, most of high-end car
manufacturers are starting to built fibers in cars to replace
traditional cooper wires. That means the huge data flow of
your in-vehicle DVD, GPS, and control signals can be transmitted
by broadband fibers at the same time. Therefore the POF solution
is capable of providing a safe and quality driving environment
for all the drivers. |
