I've almost seen it all now..

Went to do a service on a down MDF and reported back that connectors where is great shape and the issue may be somewhere in the road (didn't have our OTDR on that visit) Customer came back few days later after they had the company who installed the fiber come back and replace it from the street. We came back to this after it still wasn't working...

New splice, new heads and we're sailing now 😎
