13. If power is applied and the database already exists on the NMIC, the optical card will boot.
Once completed booting, the Port LED should turn green indicating it is receiving a good
input signal. If the LED remains red, it indicates a Loss of Signal is present. In this case, go
back to step 3 and recheck the input and output connections of the fibers. If they are
correct, check the far end source. Determine and fix the problem before continuing.
14. If an optical power meter indicates a signal is present on the fiber, and it meets the input
signal specification of the card, clean the module fiber connector to ensure there is no
debris on the fiber itself. If the card still fails to acknowledge the input signal, it may be
defective. Verify the inbound fiber signal using another optical card. Refer to the Apps and
Engineering Phase 3.1 manual listed in the preface of this document for specifications.
C. Cleaning and Mating Instructions for Fiber Optic Connectors and Adapters
Note: Cleanliness will affect the performance of an optical fiber system. Perform the following
procedures prior to installation. Clean all connectors, adapters, and attenuators before making
any connections. Check local practices for approved cleaning methods and materials. The
following cleaning materials are recommended and may form part of your cleaning kit:
• Lint-free laboratory wipes
• Isopropyl alcohol in pressurized dispenser
• Lint-free adapter cleaning tips
• Clean, dry, oil-free compressed air
• Fiber cleaning reel
• Fiber scope
Warning: Handle, use, and dispose of chemicals in accordance with manufacturer's
instructions.
Note: When using canned compressed air, clear the nozzle with a short air blast before
blowing any parts clean. Do not shake the compressed air can. Keep the can level while
using to prevent liquid in the can from entering the air stream.
Note: the use of these cleaning products does not guarantee a clean connector. A fiber
scope should be used to ensure that the connector tip is lint free.
CLEANING
Connectors/Terminators
Note: If using a fiber cleaning reel, follow the instructions generally included on the
swiper box to advance the reel, twist the fiber end, and swipe across the track.
Otherwise, use the following procedure.
15. Fold a clean, new wipe into a 2" by 2" square pad.
