That's 3 feet if you use the right tape. At the least they could have split the block and put protection across the pins.
I believe it's 6' above the panel... Plus, you're not supposed to terminate OSP without a splice chamber, right?
That whole wall is one massive code violation.

Missing clamps for conduit
That just covers the blatant ones.
