Although the optical module interface of the data center switch transmits signals via optical fiber, the electrical pins such as the I²C management bus, Tx_Disable, and Rx_LOS are exposed to electrostatic discharge (ESD) risks and must meet the IEC61000-4-2 ±8kV contact discharge. Although the optical module interface of the data center switch transmits signals via optical fiber, the electrical pins such as the I²C management bus, Tx_Disable, and Rx_LOS are exposed to electrostatic discharge (ESD) risks and must meet the IEC61000-4-2 ±8kV contact discharge. - CloudEngine 16800, 12800, 9800, 8800, 7800, 6800, and 5800 Series Switches Troubleshooting Guide (V100 and V200) - Huawei What Are the Main Causes for and Protection Measures Against Optical Module Failures? Optical modules must be operated in a standardized manner. Any non-standard operation may. However, for the most sensitive interfaces running at low voltage, ESD protection based on dual diode at the I/O, combined with a (distributed) power clamp, is not always feasible. Fortunately, the ESD rating for these interfaces can be reduced. Because this flip-chip assembly is performed in. Damage to an ESDS (electrostatic discharge sensitive) device by the ESD event is determined by the device's ability to dissipate the energy of the discharge or withstand the voltage levels involved. This is known as the device's “ESD sensitivity”. An ESD event can occur when any charged conductor. A system-level ESD standard that shows the robustness of the ESD device.
