Question 5

What is the purpose of a heat-shrink splice protector sleeve applied after a fusion splice?

Accepted Answer

To mechanically protect and strain-relieve the splice point

Answer

To color-code the splice for identification

Answer

To increase the refractive index of the fiber

Answer

To waterproof the splice closure

Question 6

In OSP fiber splicing, what does OTDR stand for and what is its primary use during splice testing?
