To prevent damage to the fiber-optic cables, we recommend that you keep the transceivers disconnected from
their fiber-optic cables when installing the transceiver in the line card. Before removing a transceiver from
the router, remove the cable from the transceiver.
To maximize the effectiveness and life of your transceivers and optical cables, ensure the following:
• Wear an ESD-preventative wrist strap that is connected to an earth ground whenever you handle

loss should be kept below 0.35 dB.
• Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.
• Clean the connectors regularly; the required frequency of cleaning depends upon the environment.
In addition, clean connectors when they are exposed to dust or accidentally touched. Both wet and
dry cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning
procedures.
