The 45S is equipped with a mechanism linking the wind protector and fiber clamp, so when you open wind protector, the fiber clamps opens automatically (setting is adjustable).
The 45S is also equipped with fiber retention clamps, featured on our other fusion splicer models. The retention clamps prevent the fiber from jumping out after the fiber clamps are opened (setting is adjustable).
These mechanisms work in tandem to provide easy fiber handling and a reduction in the time it takes to transfer the fiber to the heater.
