Hello! If there is no “landing” OTDR jumper, place the marker just before the last event. This measures the loss across the system except for the last connector. If there is a “landing” OTDR jumper, place the marker just after the second-to-last event to measure the loss across the system in one direction. A “landing” OTDR jumper is basically an OTDR launch cable/access jumper but placed on the end of the system to see the last connector.

You need a larger OTDR. I hear there is one the size of a double door fridge. Its great for working on a pole with. You just hau it up with a crane beside you and away you go!

Hi, Thanks for the information. We don't use land/launch cables so I will place before the last event. Thanks!

Can you tell me, when I want to see the loss along a fibre link. I place one marker at the very start, but at the end where do I place the marker? Is it before the reflection from the far end connector, or is it in the middle of the reflection at the far end connector?
