One hell of a good graphic. Thanks Mark. From: Mark Radabaugh Sent: Tuesday, April 6, 2021 7:31 AM To: AnimalFarm Microwave Users Group Subject: Re: [AFMUG] GPON through MUX?
We do it. It’s limited to a single splitter but works fine. These are inexpensive fiberstore muxes: -------------------------------------------------------------------------------- Mark On Apr 5, 2021, at 10:05 PM, Chris Fabien <[email protected]> wrote: Adam, GPON is 1310/1490. There are definitely ways to overlay DWDM. We overlay 1550 RF video over our GPON and it's probably a way wider signal than DWDM would be.

DWDM C band is 1525-1565 which would overlap. DWDM L band is 1570-1625.....so yeah I guess a DWDM MUX that only touched L-Band might pass GPON through. Maybe I've been looking at it through the wrong lens. On 4/2/2021 4:24 PM, Cassidy B.
