Fiber Optics Overview

Fiber Optic Cables

• Fiber optic cables consist of a central core wrapped in layers for protection, covered with an outer plastic layer.

Connectors

• Subscriber Connector (SC):
  • Push/pull design for ease of insertion and removal.
• Local Connector (LC):
  • Smaller, similar to SC, allows for more cables in less space, commonly used for higher Internet speeds.

Internet Connection Types

• Special Fiber Internet: Uses fiber links between subscriber premises and ISP.
  • Fiber to the Premises (FTTP): Full fiber link.
  • Fiber to the Curb (FTTC): Retains a copper segment between premises and street cabinet.

Transceivers

• Small Form-factor Pluggable (SFP):
  • Fiber optic transceiver module supporting duplex 1 Gbps (SFP) or 10 Gbps (SFP+) links.
  • Essential for communication between network components based on fiber optics.
