Decreased Output Due To Contamination - Pico Macom PFT-10 Owner's Manual

PICO MACOM

8.1 Decreased Output Due to Contamination

The most likely cause of decreased optical output is contamination in the OPTICAL OUT con-
nector. The optical jumper connectors may be contaminated by the slightest touch to human
skin or other apparently clean surfaces. This contamination is transferred in to the bulkhead
connector and remains when the jumper is removed from the PFT transmitter. Over time, it
will cause decreased and intermittent output levels. Users may correct this condition as fol-
lows using commonly available fiber cleaner kits.
1. Remove fiber jumper from OPTICAL OUTPUT connector
2. Unplug unit from power source. Open top cover by removing 12 screws, sliding top plate back
and lift at rear. Find and remove internal fiber connector at OPTICAL OUT bulkhead connec-
tor and set aside. Exercise care that you do not bend or damage the internal fiber.
3. Clean bulkhead connector using Pico Macom fiber cleaning tools such as Optipop 2.5mm
stick cleaner. Slide stick into the bulkhead and scrub contamination of the bulkhead. In the
absence of commercial cleaning tools, a pipecleaner and isopropyl alcohol may be used. A
less effective solution is to use canned (clean) air with nozzle to blow contamination out of the
bulkhead.
4. Clean internal fiber connector using handheld fiber connector cleaner (as shown earlier in this
manual) and insert directly into the bulkhead connector until fully seated. If using FC type,
screw ferrule onto bulkhead connector until snug.
5. Clean and insert protective cover in inside of bulkhead connector if an external fiber connector
is not to be plugged into the PFT immediately.
6. Replace PFT top cover and snug 12 screws. Do not over tighten. Replace in rack and connect
power cord.
7. Clean external fiber (jumper) connector using handheld fiber connector cleaner (as shown ear-
lier in this manual) and insert directly into the bulkhead connector until fully seated. If using
FC type, screw ferrule onto bulkhead connector until snug.
