MXK Hardware Installation Guide
•
Follow the manufacturer’s instructions when using an optical test set.
Incorrect calibration or control settings can result in hazardous levels of
radiation.
Handle optical fibers
When you work with optical fibers, you must take these precautions:
•
Wear safety glasses when you install optical fibers.
•
Clean your hands after you handle optical fibers. Small pieces of glass are
not always visible and can damage your eyes. If you have a piece of a
glass in your eye, get medical assistance immediately.
•
Never look into an active optical fiber or a optical fiber connector opening
of an active or powered-up unit.
•
Prevent direct exposure to optical fiber ends or optical connector ends
where you can directly access the laser signal. Do not handle pieces of
optical fiber with your fingers. Use tweezers or adhesive tape to lift and
discard any loose optical fiber ends.
•
Wear rubber gloves when you clean optical connectors. The gloves
prevent direct contact with the isopropyl alcohol and prevent
contamination of the ferrules with skin oils.
•
Place all optical fiber clippings in a plastic container provided for that
purpose.
•
Handle optical fibers with caution. Place the optical fibers in a safe
location during installation.
•
Protect all optical fiber connectors with clean dust caps at all times.
•
Follow the manufacturer instructions when you use an optical test set.
Incorrect calibration or control settings can create hazardous levels of
radiation.
Optical connections
When connecting optical fiber from the OLT to the splitter or from the splitter
to the OLT do
not
confuse UPC fiber and APC fiber. Mismatching these
connectors could result in an air gap between the two connectors which could
create back reflection or other optical loss conditions.
WARNING!
Older APC connectors may not use the standard
eight degree angle and this difference could also result in an air
gap condition.
Standard connector coding:
Blue: UPC
Green: APC
