Hello, this post has some good information with some caveats: the C000000L033A Gigabit Surge Suppressor (56V) should only be used for grounding non-POE enabled ethernet cables runs (i.e. out of band management cabling). We recommend using the third party ALPU-F140 surge suppressor for any cable runs without POE. Using the C000000L033A Gigabit Surge Suppressor (56V) on cable runs without POE current may cause bit errors on the cable.
Also, the PTP820 series has built in surge suppression and it is not 100% necessary when using a PTP820 and the outdoor POE supply (also has built in suppression). However, if using the indoor POE supply, or in areas of high static, we recommend additional surge suppression. Here is some additional information, in addition to the installation guides available here.
You will end up grounding the ODU's and surge suppression equipment, and then use the grounding kits for enthernet based cabling. If you build out the design in LINKPlanner, it will assume grounding every 20ft. I would also highly recommend using outdoor rated cabling.
