Connecting the Fiber Cables to the Main Hub
CAUTION! Observe all Fiber Port Safety Precautions listed in “Safety Precautions” on page 109.
Prepare the Fiber Cables
Do the following before connecting the fiber cables:
1 Confirm that their optical loss
does not exceed the 3 dB optical budget.
2 If using fiber distribution panels, confirm that th
e total optical loss of fiber cable, from the
Main Hub through distribution panels and patch cords to the Expansion Hub, does not exceed
the optical budget.
3 Make sure the fiber cable’s
connectors are SC/APC (angle-polished). Using any other
connector type will result in degraded system performance and may damage the
equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are not SC/APC.
Refer to “Splicing Fiber Optic Cable” on page 146. Or, you can change the fiber’s connector to
SC/
APC.)
Clean the Fiber Ports
You can clean the Hub’s fiber ports using canned compressed air or isopropyl alcohol and foam
tipped swabs.
• I
f using compressed air, the air m
ust be free of dust, water, and oil, and hold the can level
during use.
• If using isopropyl alcohol
and foam tipped swabs, use only 98% pure or more alcohol.
Using Compressed Air
1 Remove the port’s dust cap.
2 Spray the compressed air away from the
unit for a few seconds to clean out the nozzle and
then blow dust particles out of each fiber port.
Using Isopropyl Alcohol
1 Remove the connector
’s dust cap.
2 Dip a 2.5mm lint-free, foam-tippe
d swab in isopropyl alcohol and slowly insert the tip into the
connector.
3 Gently twist
t
he swab to clean the port.
4 Insert a dry swab into the port to dry it.
5 Additionally, you
can use compressed air after the alcohol has completely evaporated.
