Fiber Optic and Copper Network Cabling: Types, Connectors, and Standards

What are the two main types of fiber optic cables?

Single-mode fiber (SMF) and multimode fiber (MMF).

What is the core diameter of single-mode fiber?

Approximately 8-10 micrometers.

What type of light transmission does single-mode fiber use?

Straight-line transmission of light rays.

What is the maximum distance single-mode fiber can transmit data?

Up to 100 kilometers (may need signal boost).

What are the typical speeds for single-mode fiber according to IEEE standards?

1 Gbps for 1000Base-LX and 10 Gbps for 10GBase-LX.

What is the core diameter of multimode fiber?

Approximately 50 or 62.5 micrometers.

What type of light transmission does multimode fiber use?

Multiple paths of light through the fiber.

What is the maximum distance multimode fiber can transmit data?

High speeds up to 500 meters or lower speeds up to 2 kilometers.

What are the typical speeds for multimode fiber according to IEEE standards?

1 Gbps for 1000Base-SX and 10 Gbps for 10GBase-SX.

Name a type of fiber optic connector.

Subscriber Connector (SC), Local Connector (LC), Straight Tip (ST), or Multi-Fiber Push On (MPO).

What is a key advantage of fiber optic cables?

Immune to electromagnetic interference (EMI) and low signal loss.

What is a disadvantage of fiber optic cables?

Higher cost for both cable and necessary devices.

What do transceivers do in a fiber optic network?

Convert electrical signals from Ethernet cables into light signals for transmission over fiber optic cable.

What is the function of a Small Form-Factor Pluggable (SFP) transceiver?

Supports 1 fiber channel with speeds ranging from 5 Gbps to 18 Gbps.

What is the function of a Quad Small Form-Factor Pluggable (QSFP) transceiver?

Supports 4 fiber channels with speeds up to 112 Gbps.

What is the primary purpose of network media?

To carry data signals between devices.

What is the role of the IEEE in networking?

To create standards for digital equipment to achieve compatibility and quality control.

What type of cable is commonly used for household cable internet and television?

Coaxial cable.

What is the maximum distance for coaxial cable according to IEEE standards?

185 meters.

What is a Direct Attach Copper (DAC) cable used for?

Fast connectivity between network backbone devices in data centers.

What is the maximum speed of Twisted Pair Cable?

Up to 10 Gbps for Category 6a or 7 cables.

What is plenum cable designed for?

Use in areas within buildings used for air circulation, constructed to resist fire and flame spread.

What is the significance of the National Fire Protection Association (NFPA) regarding plenum cables?

They outline stringent fire safety regulations that plenum cables must comply with.
