• A. True
• B. False
• C. Not sure
• D. Neither

Answer: (A)

Splice protectors are the protective shells that surround a joined fiber to keep moisture out and provide mechanical relief so the splice isn’t stressed by bending or pulling. The two designs you’ll see most often are heat-shrink and butterfly style. Heat-shrink protectors are sleeves placed over the splice and then heated so the material contracts tightly around the fiber and often seals with an adhesive lining. This creates a uniform, sealed, strain-relieved cover that protects the joint from environmental factors and micro-bends. Butterfly protectors are a mechanical option that clamps around the splice with two wings, forming a rigid enclosure without any heat. They’re quick to install in the field, provide solid strain relief, and protect the joint similarly from moisture and physical stress. Because both designs are widely used in different settings, the statement is true. There are other protective approaches as well, but heat-shrink and butterfly are the common ones.
