Question

question 5

what is the primary purpose of multi-fiber push on (mpo) termination?

a. to allow for low-footprint backbone or trunk cabling
b. to enhance the electrical conductivity of fiber optic cables
c. to reduce the speed of data transmission for security purposes
d. to provide a waterproof seal for underwater cables

Explanation:

Analyze the question

The question asks for the primary purpose of Multi-fiber Push On (MPO) termination.

Evaluate option A

MPO connectors bundle multiple fibers (typically 12 or 24) into a single connector. This high-density design significantly reduces the physical space required for cabling, making it ideal for high-density backbone or trunk cabling in data centers.

Evaluate option B

Fiber optic cables transmit data using light, not electricity. Therefore, enhancing electrical conductivity is irrelevant to fiber optic terminations.

Evaluate option C

MPO connectors are designed to support high-speed data transmission (such as 40G/100G Ethernet) by using parallel optics. Reducing transmission speed is not their purpose.

Evaluate option D

MPO connectors are standard indoor/datacenter connectors and are not specifically designed to provide waterproof seals for underwater cabling.

Answer:

• (A) To allow for low-footprint backbone or trunk cabling (Correct answer)
• (B) To enhance the electrical conductivity of fiber optic cables
• (C) To reduce the speed of data transmission for security purposes
• (D) To provide a waterproof seal for underwater cables
