Question 1

On singlemode optical fiber, a convex physical contact (PC) connector delivers return loss performance in the range of:

a. 20 dB to 30 dB
b. 50 dB to 60 dB
c. 40 dB to 50 dB
d. 30 dB to 40 dB

Answer 1

c. 40 dB to 50 dB

p 6-93

Singlemode optical fiber jumpers typically feature a convex PC polish on the end of the fiber terminated connector ferrule surface to ensure proper fiber contact. This connector design reduces the Fresnel reflection and delivers return loss performance in the range of 40 dB to 50 dB.

On singlemode optical fiber, an APC connector features a slight angle (8 degrees) to further reduce reflectance, resulting in better return loss than PC connectors (60 dB).

Question 2

Fusion optical fiber splices shall have a minimum return loss of _____ for multimode fiber.

a. 30 dB
b. 26 dB
c. 20 dB
d. 12 dB

Answer 2

c. 20 dB

p 6-87

Fusion and mechanical optical fiber splices shall have a minimum return loss of 20 dB for multimode and 35 dB for singlemode

Question 3

SC-style optical fiber connector’s disadvantage is that it does not feature an SFF design.

a. True
b. False

Answer 3

a. True

p 6-82

Question 4

Fusion and mechanical optical fiber splices shall have a minimum return loss of _____ for singlemode fiber.

a. 35 dB
b. 26 dB
c. 20 dB
d. 12 dB

Answer 4

a. 35 dB

p 6-87

Fusion and mechanical optical fiber splices shall have a minimum return loss of 20 dB for multimode and 35 dB for singlemode.

Question 5

The standard coaxial connector for use on RG59, Series-6 and Serie-11 cable is the:

a. BNC-style connector
b. N-style connector
c. F-style connector

Answer 5

c. F-style connector

p 6-95

The F-style connector is the standard connector for use on RG59, Series-6, and Series-11 cable. The pin connector is the standard connector for semirigid aluminum coaxial cable.
