Could some one point me the right way on optimizing the upstream link on a 6940
I only have one 6.4MHz wide QAM 64 carrier centered at 35 MHz. My plant has no actives aside from node itself. Node to term tap.
What level should I be hitting the transmitter with in order to optimize the upstream with the above mentioned upstream loading? I belive the transmitter is a 2dBm standard gain TX. Should I just use a 0 dB RF pad in the transmitter input, or should I derate the actual drive level hitting the laser because of the channel loading?
Any help would be greatly appreciated
