Splice Operation
* Hold the fiber at edge of splicer body.
** Apply tension to the fiber until heater
holds the fiber.
• When splicing only standard SM fibers (ITU-T G.652),
“SM AUTO” mode is recommended.
• When splicing different types of fibers, “AUTO” mode is
recommended, but splice speed is slow.
• When splicer indicates following message, splice
loss may be high
“Arc discharge is not stable. Electrodes should be
stabilized to reform the arc discharge.”
• Load prepared SM fibers onto splicer in order to
stabilize electrodes. After completeing it, re-splice
fibers.
• When an altitude changes drastically, stabilizing
elctrodes must be excecuted before splicing.
Note
Placing Fiber Holder
• Do not reverse Fiber Holder
when placing onto splicer.
Set in the direction which sees
from the sheet key side and
can read the name of a holder.
*Hold

the fiber coating edge to
holder edge
• Make sure the stripped fiber is free
of coating debris or contamination.
• Use only 99% or better purity alcohol.
• Hold lid firmly
• Free of any gel residue
• Hold this point firmly
