1. Analysis of common causes of optical transceiver module damage.
The pollution and damage of the optical interface cause the loss of the optical link to increase, resulting in the failure of the optical link. The reasons are:
a. The optical port of the optical transceiver module is exposed to the environment, and the optical port is polluted by dust entering;
b. The end face of the optical fiber connector used has been polluted, and the optical port of the optical transceiver module has been polluted twice;
c. Improper use of the end face of the optical connector with pigtail, scratches on the end face, etc.
d. Use inferior fiber optic connectors.
e. Improper plugging and unplugging, broken ceramic sleeve, etc.
2. ESD damage for the optical transceiver module
ESD(ElectroStatic Discharge). Static electricity will absorb dust, change the impedance between lines, and affect the function and life of the product; the heat generated by the instantaneous electric field or current of ESD will damage the components, and it can still work in a short period of time but the life is affected; Even destroy the insulation or conductor of the component, so that the component cannot work (completely destroyed).The factors that cause ESD damage are:
a. The environment is dry and prone to ESD;
b. Abnormal operations, such as: non-hot-swappable optical transceiver module live operation; direct contact with the static-sensitive pins of the optical module without electrostatic protection; no anti-static packaging during transportation and storage;
c. The equipment is not grounded or is poorly grounded.
