[c-nsp] 10G SFP+ ASR9001 LOS

Hi, for some month i see sporadic LOS on a 10G circuit from a ASR9001 to one of our Upstreams. It began when i removed some media-converter from single mode to multi mode inbetween so that a SFP+ 1310nm 10km transceiver is now plugged into the ASR. The LOS can be cured shut/no shut on the
