Follow these guidelines to ensure the performance of your GBIC:
‰ GBICs are static sensitive. To prevent electrostatic discharge
damage (ESD), follow your normal board and component
handling procedures.
‰ GBICs are dust sensitive. When the GBIC is stored or when a fiber-
optic cable is not plugged in, always keep plugs in the GBIC
optical bores.
‰ The most common source of contaminants in the optical bores is
debris picked up on the ferrules of the optical connectors. Use an
alcohol swab or wipe to clean the ferrules of the optical
connector.
