Fiber Optic Cables

1. Overview

Fiber optic cables are advanced transmission media that use light pulses to carry data through flexible glass or plastic fibers. They enable high-speed, long-distance communication with superior bandwidth and immunity to electromagnetic interference. As critical infrastructure in modern technology, these cables support global internet connectivity, telecommunications networks, and high-precision industrial systems.

2. Main Types & Functional Classification

Type	Functional Features	Application Examples
Single-Mode Fiber (SMF)	9/125 m core/cladding, laser light source, low attenuation	Long-haul telecom backbones, 5G networks
Multi-Mode Fiber (MMF)	50/125 m or 62.5/125 m core, LED light source, higher dispersion	Data centers, local area networks (LANs)
Tight Buffered Cable	Individual fiber coating with polymer, flexible for indoor use	Building internal wiring, patch cords
Loose Tube Cable	Waterproof gel-filled tubes, durable for outdoor environments	Underground installations, aerial deployments
Ribbon Fiber Cable	Flat ribbon structure with multiple fibers, high-density design	High-capacity data centers, fiber-to-the-home (FTTH)

3. Structure & Composition

A typical fiber optic cable consists of four concentric layers:

Core: Glass (silica) or plastic center (5-50 m diameter) for light transmission
Cladding: Lower-refractive-index material (125 m) to contain light via total internal reflection
Coating: UV-cured acrylate layers (250 m total) for mechanical protection
Outer Jacket: Flame-retardant polymer (PVC/LSZH) with strength members (aramid yarn, steel)

4. Key Technical Specifications

Parameter	Description	Importance
Attenuation	0.2-0.3 dB/km (SMF), 2.5-3.5 dB/km (MMF)	Directly affects transmission distance
Bandwidth	10-100 GHz km (MMF), virtually unlimited (SMF)	Determines data capacity
Operating Wavelength	1310nm/1550nm (SMF), 850nm/1300nm (MMF)	Matches light source characteristics
Minimum Bend Radius	20 cable diameter (standard), 10 (bend-insensitive fibers)	Prevents microbending losses
Temperature Range	-40 C to +70 C (standard), -55 C to +85 C (specialty)	Ensures reliability in extreme conditions

5. Application Fields

Telecommunications: Core/backbone networks, submarine cables
Data Centers: Inter-server connections (400Gbps/800Gbps systems)
Medical: Endoscopy imaging, surgical lasers
Military: Secure communication systems, radar
Energy: Power grid monitoring, oil/gas pipeline sensing
