Study Notes

Fiber-Optic Cabling Types

Single-Mode Fiber (SMF) has a very small core and uses expensive lasers for long-distance applications.
Multimode Fiber (MMF) has a larger core and uses less expensive LEDs, transmitting at different angles up to 10 Gbps over 550 meters.
MMF has greater dispersion than SMF, resulting in increased signal loss over time.

Fiber-Optic Cabling Usage

Fiber-optic cabling is used in four industries: Enterprise Networks, Fiber-to-the-Home (FTTH), Long-Haul Networks, and Submarine Cable Networks.

Fiber-Optic Connectors

Connector types include: Straight-Tip (ST), Subscriber Connector (SC), Lucent Connector (LC), Simplex, Duplex, and Multimode LC Connectors.

Fiber Patch Cords

Types of fiber patch cords include: SC-SC MM Patch Cord, LC-LC SM Patch Cord, ST-LC MM Patch Cord, and ST-SC SM Patch Cord.
Yellow jackets are used for single-mode fiber cables, while orange (or aqua) is used for multimode fiber cables.

Fiber versus Copper

Fiber-optic cabling is primarily used for high-traffic, point-to-point connections between data distribution facilities and for building interconnections in multi-building campuses.
Comparison of fiber-optic and UTP cabling:
- Bandwidth: Fiber-optic (10 Mb/s - 100 Gb/s), UTP (10 Mb/s - 10 Gb/s)
- Distance: Fiber-optic (1 - 100,000 meters), UTP (1 - 100 meters)
- Immunity to EMI and RFI: Fiber-optic (completely immune), UTP (low)
- Immunity to electrical hazards: Fiber-optic (completely immune), UTP (low)
- Media and connector costs: Fiber-optic (highest), UTP (lowest)
- Installation skills required: Fiber-optic (highest), UTP (lowest)
- Safety precautions: Fiber-optic (highest), UTP (lowest)
