Study Notes

Fiber-Optic Cabling in Enterprise Networks

Main purpose: To enable high-speed and high-bandwidth data transmission across extensive distances in enterprise networks.
Key advantage: Fiber-optic cabling supports much higher data rates compared to UTP (unshielded twisted pair) cabling.

Types of Fiber-Optic Cables

Multimode fiber: Has a larger core and uses less expensive LEDs for transmission, making it suitable for shorter distances.
Single-mode fiber: Features a very small core and utilizes costly lasers, making it ideal for long-distance applications due to minimal signal loss.

Light Pulse Characteristics

Dispersion: Refers to the spreading out of a light pulse over time in fiber-optic cabling, which can affect signal quality.

Fiber-Optic Connectors

Common type used: Subscriber Connector (SC) for connections due to its reliability and ease of use.
Duplex Multimode LC Connectors: Allow for full-duplex communication, enabling simultaneous data transmission and reception.

Fiber Patch Cords

Primary purpose: To connect devices to a network via fiber-optic connectivity, facilitating network expansion and flexibility.

Fiber-Optic Cable Specifications

Multimode fiber cable jacket color is typically orange.
Single-mode fiber cable jacket color is commonly yellow.

Advantages of Fiber-Optic over Other Media

Greater bandwidth capacity: Fiber can transmit data over longer distances without degradation, unlike traditional copper cables.

Multimode Fiber vs. UTP Cabling

Despite being effective for certain applications, multimode fiber is less common than UTP cabling due to lower installation costs and the latter's sufficient performance for many business environments.
