How Should Aerial Cable Be Affixed To Poles?

I need to install an aerial cable over a parking lot to an existing light pole where a camera will be installed (wireless isn't an option). The cable is a hybrid 3 conductor power and 6 strand fiber. In addition to the guide wire and lashing cable; what other hardware would be needed to relieve strain where the cable meets the wall or pole. There must be a device that prevents the cable from pulling away and helps maintain the 6 inch bend radius.

This is a good question.  I suspect that potential ice and wind loads can affect the answer.  In my area of the US, these cable dressings are used to hang cable/fiber from hooks at the pole.  

They seem to work well in most applications and don't need to be fixed.  But again, the weather in the area may affect which solution is best.

Brain,

This is fine when the fiber is passing over the pole, but once the fiber needs to bend to each an enclosure how is the fiber supported?

I was taught you pay out 5% at both ends in loops (total of 10% length in loops) to accommodate for sagging.  The support for the loop comes from those wire lashing run around the coiled loops.

Thanks, Und1. I made the callouts bigger for readability:
