3.5.7. Filaments
The filaments are omega-shaped resistive heaters. Proper filament selection
and splice parameters are essential for optimum splice performance. Graphite
filaments are capable of achieving the high temperatures necessary for
splicing large-diameter fibers, making them ideal for most applications. Iridium
filaments operate at slightly lower temperatures than graphite filaments,
making these ideal for working with softer glass fibers. The filaments have an
approximate operation lifetime of 40 minutes, which depends on a number of
factors such as argon quality, splice duration, and fiber glass quality
.
