Laser Emitters

Earlier this month I was asked to assist a customer with a 32 link, DTX Series system. The customer failed to understand what transparent point-to-point transmission actually means and I will be addressing this in my next posting.

What I do want to talk about is safety precautions that need to be taken when working with fibre optic transmission equipment that use Laser Emitters. Both our Fibre Pro and DTX Series use laser emitters. These Lasers provide stimulated emission, i.e. they are on all the time.

The Fibre Pro and DTX Series products emit intense infrared light at 1310nm and 1550nm which is invisible to the human eye. This radiation can permanently damage the retina of the human eye. The diagram below shows the visible and invisible light spectrum.

All Fibre Pro and DTX Series products are packaged in antistatic bags that are sealed with a cautionary notice. Please read the notice before tearing the seal. The notice is there for your safety.

Please take the following precautions:

1. Never look into the source or the fibre cable.
2. Never power-up the source useless the fibre optic cable is connected to it.
3. Always keep the protector cap on the source if no fibre optic cable is connected.
4. Be cautious!!!
