Question 1

What is the IEC standard classification for a physical-contact (PC) optical fiber connector polish?

Accepted Answer

IEC Grade B

Answer

IEC 61300-3-35 classifies physical-contact (PC) polished connectors as Grade B, with defined limits for scratch and pit defects on the ferrule end-face.

Question 2

Which wavelength is primarily used for testing and transmitting data on OM3/OM4 laser-optimized multimode fiber?

Accepted Answer

850 nm

Answer

OM3 and OM4 multimode fibers are laser-optimized for use with 850 nm VCSELs, which are cost-effective light sources for short-distance applications.

Question 3

What is the minimum bend radius for optical fiber cable during installation to prevent signal loss and physical damage?

Accepted Answer

20 times the cable diameter

Answer

During installation, the minimum bend radius for optical fiber cable is 20 times the cable outer diameter to prevent microbending losses and physical damage.

Question 4

In a BICSI fiber optic system, what is the purpose of using an APC (angled physical contact) connector?

Accepted Answer

To reduce back-reflection (return loss) by angling the ferrule end-face

Answer

APC connectors have an 8-degree angled end-face that redirects reflected light away from the fiber core, significantly reducing back-reflection (return loss).

Question 5

What maximum channel loss budget does ANSI/TIA-568 allow for an OM4 multimode fiber horizontal channel?

Accepted Answer

2.9 dB

Answer

ANSI/TIA-568 specifies a maximum channel loss budget of 2.9 dB for an OM4 multimode fiber horizontal channel, covering the cable and connectors.
