Intro to Fiber Optic

Figure 1

Figure 1 shows fiber optic cable structure. Choose the CORRECT function of cladding.

• Transports optical data signals

• Protects glass from surface scratches and surface contaminants

• Reinforce the fiber core, help absorb shock and provide extra protection against excessive cable bends

• Protect the core against crushing forced and excessive tension during installation

What are the two general types of fiber optic cable found in current networking environments?

• Red and Green
• Singlemode and Multimode
