The real hot ones are just a time slice I presume so you would have to take the attenuator in and out of the circuit synched on the ont transmit schedule. Pads on hot ONTs seem to be the only solution to me.

We were testing a different brand of XGS-PON transceiver. It works fine, except clients stronger than about -14 don’t connect. Our current brand alarms at -10, but functions as high as -7, so our design assumes -10 as a cutoff. We can go around and pad the hot ONT’s, but it would be super convenient if we could magically add 5dB to only the real hot ones. …. we could just not use the transceiver, but it’s a lot cheaper than what the OLT manufacturer is selling us so it would be nice to make it work. -Adam From: AF <[email protected]> On Behalf Of Chuck McCown via AF Sent: Tuesday, July 11, 2023 11:01 AM To: AnimalFarm Microwave Users Group <[email protected]> Cc: [email protected] Subject: Re: [AFMUG] “Low pass” attenuator Curious, where would you have two signals of different amplitude in a fiber system? PON return signals? From: Adam Moffett Sent: Tuesday, July 11, 2023 5:07 AM To: AnimalFarm Microwave Users Group Subject: [AFMUG] “Low pass” attenuator Is there such a thing as a fiber attenuator that only attenuates a signal higher than some threshold? I’m thinking to prevent overloading a receiver, but let weaker signals pass unimpeded.
