Fiber teks best friend

OTDR, this unit is awesome. I do I&M and this is a fantastic tool to have. Unsure which port to use at an fdt, use the vfl and put your comfy shoes on and walk to the far end. I think not. I can pick not only the longest fiber but the one with the least loss. A recipe for success.
I did have an issue with my original unit. The friends at YEDEMC promptly addressed my issue with a free direct return and a brand new unit. Completely satisfied. Thank you!
