Polarity Management (for Splice Cassette)
Polarity management is critical during the splicing process. Corning Optical Communications
offers two different splice cassette wiring options: Straight Through or Universal Wiring. Figure 5
depicts the way the ribbon fibers should be spliced in order to achieve the polarity management
desired.

WARNING:
Never look directly into the end of a fiber that may be carrying laser
light.
Laser light can be invisible and can damage your eyes. Viewing it directly
does not cause pain. The iris of the eye will not close involuntarily as when viewing a
bright light. Consequently, serious damage to the retina of the eye is possible. Should
accidental eye exposure to laser light be suspected, arrange for an eye examination
immediately.
CAUTION:
Cleaved or broken glass fibers are very sharp and can pierce the skin
easily. Do not let these pieces of fiber stick to your clothing or drop in the work area
where they can cause injury later. Use tweezers to pick up cleaved or broken pieces
of glass fibers and place them on a loop of tape kept for that purpose alone.
Good
housekeeping is very important.

Splicing blue to blue and aqua to aqua
provides a fiber-one to fiber-one transmission.
Splicing aqua to blue at one end and
blue to blue at the other end provides
a one-to-two transmission.
