Have a question concerning latency in MXP for ONS 15454 MSTP. How do you define and measure it? I mean in for MXP you basically mux many client signals in to one lambda. Since this muxing requires O-E-O process there got to be some latency? Or is the values to small that it become neglible and we dont have to worry about it. My customer is asking me this and I cant come up with a definitive answer. To me there's practically none, it work at optical level, as to determine latency it is enough just from looking and end-to-end ping result on client side. Apreciate your expert advice.
