What is the core diameter of a standard OM4 multimode optical fiber?
Answer: 50 µm
OM4 multimode optical fiber has a core diameter of 50 µm and is optimized for use with 850 nm VCSELs.
Which type of optical fiber connector is specified by ANSI/TIA-568 as the standard for horizontal backbone cabling?
Answer: SC connector
The SC (Subscriber Connector) duplex connector is specified by ANSI/TIA-568 as the standard for optical fiber horizontal backbone cabling.
What is the maximum insertion loss allowed for a single fusion splice in an optical fiber backbone link?
Answer: 0.1 dB
BICSI and ANSI/TIA standards allow a maximum insertion loss of 0.1 dB per fusion splice in optical fiber backbone links.
What does 'OM5' designate for optical fiber, and what is its primary advantage?
Answer: A wideband multimode fiber supporting multiple wavelengths between 850–953 nm
OM5 is a wideband multimode fiber that supports multiple wavelengths between 850 and 953 nm, enabling wavelength division multiplexing (WDM) for higher capacity.
In optical fiber testing, what does OTDR stand for and what is its primary purpose?
Answer: Optical Time Domain Reflectometer; locates faults and measures fiber length and loss
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.
What is the nominal attenuation of OS2 single-mode fiber at 1310 nm?
Answer: 0.4 dB/km
OS2 single-mode fiber has a nominal attenuation of approximately 0.4 dB/km at 1310 nm as specified in ITU-T G.652D and ANSI/TIA standards.
