at the same time. De-dusting using a vacuum cleaner is easy to operate and of low cost
conserving. But this method cannot de-dust thoroughly and cannot effectively remove the
noxious gas attached on the surface of the card.
When using the cleaning agent, use anhydrous, non-corrosive, non-conductive, and high-
volatile cleaning agent dedicated for the circuit board to de-dust the card, IPA (isopropyl
alcohol) for example. The advantage of using cleaning agent is thorough and can
effectively remove the harmful particles attached on the surface of the card. This method
is characterized with difficult operation and high cost.
6.2.3 De-dust Optical Interface and Pigtail Connector
To ensure the stable running of the device, de-dusting the optical interface and pigtail
connector on the device regularly is necessary.
The de-dusting process is as follows:
Step 1:
Remove the optical fiber connected to the optical interface when cleaning the
optical interface.
Step 2:
Use the dedicated cleaning tools and materials when cleaning the optical
interface and pigtail connector. These materials can be purchased from the
optical fiber or optical cable manufacturer.
Use the dust cap to cover the unused optical interfaces on the board and pigtail.
For the optical interface in using, use a dust cap to cover the optical interface and the
pigtail connector connected by the optical interface when the pigtail requires to be
removed. In this way, on the one hand, the invisible laser sent by the laser maser can be
prevented radiating human eyes. On the other hand, the dustproof function is available to
avoid the loss of the optical interface contaminated with dust or pigtail connector being
increased.
Before de-dusting the optical interface, remove the corresponding interface daughter card
at first and ensure that the normal deployment of the system service will not be affected.
For the high-power laser interface, use the cleaning tool and material for cleaning.
For the small-power optical interface, use the clean and dry anti-static soft rush to remove
the dust on the surface of the optical interface if the dedicated cleaning tool and material
cannot be obtained.
