You need to replace a fiber optic cable that is connecting two switches together. You inspect the existing fiber cable and determine that it uses LC connectors. You also notice the cable's ferrule has a slight slant to it. Which polish grade should you use to replace the existing cable?

Answers

Answer 1

Angled Physical Contact polish

So, To replace the fiber optic cable that connects two switches. If it is found that the existing fiber cable to ensure it has LC connectors and also if the cable's ferrule has a slight slant to it.

Angled Physical Contact polish should be used to replace the existing cable.

What is Angled Physical Contact polish?

APC Connector is a type of fiber connector that reduces back-reflection by applying a 5° to 15° angle-polish to the end faces.

Because of the angle, the reflected light escapes into the cladding rather than remaining in the fiber core.

Angled connectors should only be mated with other angled connectors. When mated to a non-angle polished connector, insertion loss is extremely high. Angle-polished connectors typically have a higher insertion loss than good quality straight physical contact connectors.

When connected, "Ultra" quality connectors may achieve back reflection comparable to an angled connector, but an angled connection maintains low back-reflection even when the output end of the fiber is disconnected.

two structural elements with the same dimensions are compared. the structural element with a larger modulus of elasticity (e) isO heavier O less stiff O stiffer O less strong O stronger

Answers

The structural element with a larger modulus of elasticity (e) is stiffer. The modulus of elasticity is a measure of the stiffness of a material, and a larger modulus of elasticity indicates a stiffer material.

Stiffer means that the structural element with a larger modulus of elasticity will be less flexible and will be more resistant to deformation under load. It will also be able to support a greater load before reaching its yield point. On the other hand, the structural element with a smaller modulus of elasticity will be more flexible and will be more susceptible to deformation under load. It will also be able to support a smaller load before reaching its yield point.

What are OSHA Standards?

OSHA standards are guidelines that specify how companies must safeguard their employees from dangers. OSHA rules are divided into four categories: general industry, building, maritime, and agriculture. (The General Industry set relates to the greatest number of people and workplaces.)

OSHA standards include requirements to provide protective clothing, prevent tunneling cave-ins, reduce exposure to some communicable diseases, guarantee the safety of workers entering confined spaces, prevent exposure to potentially harmful substances such as asbestos and lead, and install machine guards, among other things.
