Sorry to correct, you but the simple answer is Yes. The limits and requirements are based on output of the light source be it LED or helium neon laser.LEDs have long been emitting enough light to be classified and Class I or Class II with all the requisite certification procedures handled thro

How to prevent damage to optical detectors/receivers in optical fiber neworks

Hi all, I'm sure this is the right forum for thus question, but maybe I'll get lucky.. In optical fiber networks, receivers used for high optical data rates (PIN diodes, APD etc) are quite sensitive to high optical power On the other hand, test equipment (OTDR or other) uses high optical power
