1. ) Optical Fiber (250 microns)
2. ) Buffer (900 microns)
3. ) Strength Member (Kevlar)
4. ) Jacket (2mm or 3 mm)

Question 8

Define Duplex cordage?

Answer 8

Called a zip cord, has two simplex cords that allow for XMIT and RCV

Question 9

Define Distribution cable?

Answer 9

Multiple tight- buffered fibers bundled in jacket with strength member. Used in Inter-building routing

Question 10

Define Breakout Cable?

Answer 10

Multiple simplex cables bundled with a strength member. Ideal if connecting cable directly to equipment.

Question 11

Define Armored Cable?

Answer 11

Used for outdoor, direct burial.

Protects from animals gnawing on the cable.

Question 12

Define Messenger Cable?

Answer 12

Used when cable must be suspended between poles.Have an extra strength member to support the weight of the cable.

Question 13

Define Ribbon Cable?

Answer 13

Contains 4, 8 or 12 fibers side by side. Take up less room and has increased bandwidth.

Question 14

Define Submarine Cable?

Answer 14

Designed to carry signals under bodies of water. May be buried, or sit on ocean/body of water floor.

Question 15

Define Hybrid Cable?

Answer 15

Contains both Single and Multimode fiber within one cable.

Question 16

Define Composite?

Answer 16

Has both optical fiber and current-carrying electrical conductors.

Question 17

What does a fan-out Kit do?

Answer 17

Converts loose-buffered fibers into tight buffered fibers for containerization. Converts loose buffer optical fiber to tight buffered 900 um fiber.

Question 18

What does a Breakout Kit do?

Answer 18

Converts loose-buffered fibers into simplex cordage. Allows use of standard connectors to hook up to equipment directly.
