Signal division over multiple optic fibre cables

[chaudhurysid]

I want to transmit a signal over seven fibre optic cables simultaneously. The input will be from a copper cable, input voltage 24V. Can anyone suggest a device/method to do this which can help me do this.

For experimentation, try gathering the fibers into a short length of heat shrink tubing, position the ends firmly against an LED, then heat the assembly to secure it (or wrap tape around it).

It may be tricky to get adequate illumination through all the fibers.

With a 24V signal you need to add a safety resistor, to prevent the LED from frying.

if the signal is less than 24V then there is a need of resistor is required or not and if not then what will be its effect over the LED ... help..

A typical safe current is 20 mA.

However it could be greater for a high-performance led.

I would not know what the minimum brightness should be, nor which color wavelength is best, in order to obtain furthest travel, or fastest communication speed, etc.
