Abnormal operations, such as: non-hot-swappable optical module live operation; directly touching the static-sensitive pins of the optical module without electrostatic protection; no anti-static packaging during transportation and storage, no grounding or poor groundingAbnormal operations, such as: non-hot-swappable optical module live operation; directly touching the static-sensitive pins of the optical module without electrostatic protection; no anti-static packaging during transportation and storage, no grounding or poor groundingDust prevention and cleaning: Details determine success or failure 1) Unused protection: When an optical module is not in use, a dust cap must be installed to prevent dust from entering the port and causing poor contact. 2) Cleaning specification: Use special wiping paper or dust-free cotton swab. An optical module is a critical component in modern optical communication systems, directly affecting transmission stability, network reliability, and operational efficiency. However, during installation and daily operation, various issues may arise. After an optical module is inserted, the console port displays alarm information. Through everyday use, optics can come in contact with contaminants such as dust, water, and skin oils.
