In the series of splicing process, cleaving fibers are one of most important process to get low splicing loss.
In the case, improperly cleaving may cause not only bad cleaving but also cause high splicing loss.
The principle of cleaving a optical fiber by cleaver shows as below.
① Clamp a optical fiber with upper and lower clamp pad
② Score the fiber by a cleaver blade
③ An anvil pushes and bends the fiber from upper side,
finally the fiber is cleaved.
