Grok is nothing more than a made up term found in “Stranger in a strange land”. Written by RAH

I don’t know the answer (your reasoning sounds persuasive), but seriously are saying “Grok this” now instead of “Google this”?

 

If so, we’re starting to sound like cavemen.

Definition from ITU G.987:

3.3.15 tolerance to reflected power (transmitter): A transmitter parameter that characterizes the

maximum admissible ratio of the average reflected optical transmit power incident at the transmitter

to the average optical transmit power. 

 

If my average transmit power is +6dBm and the tolerance to reflected power is -15dB, then 6 - 15 = -9, so reflected power as strong as -9dBm won't harm the transmitter?  

Is it that easy or am I misunderstanding the definition?
