Check the model of the faulty optical module. If it is not a Huawei-certified optical module, replace it with a Huawei-certified optical module. If the optical module is installed on a GE port, run the display interfaceGigabitEthernet x/x/x command to view port information when the optical module. The Cisco 8000 series routers utilize Cisco's Silicon One ASIC to deliver full routing functionality at higher capacities and a lower environmental footprint than any other routing silicon available. The transmitting interface inputs electrical signals of a certain bit rate, which are then processed by internal driver chips. Subsequently, the driver semiconductor laser. Optical modules (also known as fiber optic transceivers) are essential components in modern communication networks, enabling high-speed data transmission by converting electrical signals into optical signals and vice versa.
