The advantages of placing the OVP at pins P1, P2 rather than in the front of the filter (pins 1, 2) are (a) for VDSL applications the first inductor shields the high frequency signals from the effect of the capacitance or capacitance imbalance of the VOP and (b) the extra inductor between primary and secondary protection circuits during surge events. Application circuit A can be used to protect against differential (transverse) surge; Application circuit B protects against differential and common mode (longitudinal) surges. Which of these is required will depend on the details of the system such as ground terminations during surge testing and the effect of other protection devices in the system. Typically OVPs with breakover voltages of 360V would be used but the value can be chosen to suit the application. It’s recommended that the breakover voltage should not exceed 500V in order to guarantee protection of the filter components.
