with pre-attached copper cables. When installing fiber-optic cables for a port, you must install SFP transceivers
for 1-Gigabit optical ports or install SFP+ transceivers for 10-Gigabit optical ports or QSFP+ transceivers for
100-Gigabit ports before installing the fiber-optic cable in the transceivers.
Caution
Removing and installing a transceiver can shorten its useful life. Do not remove and insert transceivers more
than it is absolutely necessary. We recommended that you disconnect cables before installing or removing
transceivers to prevent damage to the cable or transceiver.
Disconnect Optical Ports from the Network
When you need to remove fiber-optic transceivers, you must first remove the fiber-optic cables from the
transceiver before you remove the transceiver from the port.
Maintain Transceivers and Optical Cables
To maintain high signal accuracy and to prevent damage to the connectors, transceivers and fiber-optic cables
must be kept clean and free of dust. Attenuation (loss of light) is increased by contamination and should be
below 0.35 dB.
Consider the following maintenance guidelines:
• Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is
• Do not remove and insert a transceiver more than it is necessary. Repeated removals and insertions can
• Keep all optical connections covered when not in use. Clean them before use to prevent dust from
• Do not touch the ends of connectors. Touching the ends would leave fingerprints and cause other
• Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In
