• Electronically tuned ultrasonic blade • For
multi-mode and single-mode fiber • End angle consistently < 1° • For
laboratory and field use • Easy to handle
The most revolutionary
aspect of the EFC 11 is the ultrasonic cleaving action. A precision diamond
blade is attached to a resonant acoustic-stepped horn. The ultrasonic horn
resonance is started and maintained for the duration of the cleave by an
electronic circuit. It is then automatically terminated to preserve battery
life.
The ultrasonically vibrating blade moves slowly towards the
tensioned fiber on stiction-less damped bearings. Cleaving takes place without
the compressive stresses and blade intrusion into the fiber that is typical of
conventional cleavers. This revolutionary new cleaving technique produces superb
planar ends of mirror quality with no hackle.
Operation
A stripped
and cleaned fiber is placed in the grooves of the cleaver and is held by
specially designed lowtorsion clamps. Constant tension is then applied to the
fiber by lowering the tension lever. Cleaving is initiated by pushing the blade
release lever downwards. The design allows cleaving to take place as close to
the coating as may be required.
The EFC 11 fiber cleaver has been
designed to provide trouble-free cleaving over many thousands of cleaves. This
design does not require constant adjustment to stay "in tune". In the event of
accidental damage to part of the diamond edge, the operator can adjust the blade
to bring a new part of the cutting edge into
use.
