The WB3176 cable is a superior ESSEX cable, which is a superior CAT5E cable. Probably the biggest differnce is the shield part and gel filled in this cable. see pic below. For that reason, the cable is more riggid than PTP 820S normal cable and you need aware during your installation.
This cable certainly support PTP 820S, i would say it is a overkill for PTP 820S installation.
