Question 1

What is the core diameter of a standard OM4 multimode optical fiber?

Accepted Answer

50 µm

Answer

OM4 multimode optical fiber has a core diameter of 50 µm and is optimized for use with 850 nm VCSELs.

Question 2

Which type of optical fiber connector is specified by ANSI/TIA-568 as the standard for horizontal backbone cabling?

Accepted Answer

SC connector

Answer

The SC (Subscriber Connector) duplex connector is specified by ANSI/TIA-568 as the standard for optical fiber horizontal backbone cabling.

Question 3

What is the maximum insertion loss allowed for a single fusion splice in an optical fiber backbone link?

Accepted Answer

0.1 dB

Answer

BICSI and ANSI/TIA standards allow a maximum insertion loss of 0.1 dB per fusion splice in optical fiber backbone links.

Question 4

What does 'OM5' designate for optical fiber, and what is its primary advantage?

Accepted Answer

A wideband multimode fiber supporting multiple wavelengths between 850–953 nm

Answer

OM5 is a wideband multimode fiber that supports multiple wavelengths between 850 and 953 nm, enabling wavelength division multiplexing (WDM) for higher capacity.

Question 5

In optical fiber testing, what does OTDR stand for and what is its primary purpose?

Accepted Answer

Optical Time Domain Reflectometer; locates faults and measures fiber length and loss

Answer

An OTDR (Optical Time Domain Reflectometer) sends pulses into a fiber and measures reflected light to locate faults, splices, and connectors, while measuring fiber length and loss.
