Question

Epoxy material in fibre optics is intended for ____ .

• A. Better optical properties
• B. Better reflection
• C. Better sealing
• D. Reducing noise

Hint:

Epoxy in Fiber Optics. Primarily used in connectors and splices for mechanical bonding, strain relief, and environmental sealing to protect the fiber ends.

Answer 1

The Correct Option is C

Epoxy resins are often used in fiber optic applications, particularly in connectors and splices
Their primary role in these contexts is mechanical and environmental protection
- Sealing: Epoxy provides a robust seal against moisture, dust, and other contaminants that could degrade the optical surfaces or the fiber itself over time
- Mechanical Strength/Strain Relief: It helps to secure the fiber within the connector ferrule, providing mechanical stability and protecting the delicate fiber from stress
While proper application aims not to degrade optical properties or increase noise, the main intended purposes relate to mechanical integrity and sealing against the environment, ensuring long-term reliability of the connection
Better optical properties or reflection are characteristics of the fiber core/cladding and coatings, not typically the epoxy itself
