Optical Fiber Cables
Optical Fibers Single-Mode Fibers
Core diameter 9 µm, so there is only place for one single mode (light beam) minimum attenuation and highest bandwidth.
Dispersion is the spreading of a light pulse as it travels down a fiber. (Chromatic and Material dispersion)
Bandwidth is the amount of information a fiber can carry so that every pulse is distinguished by the receiver at the end.

Optical Fiber Cables
Optical Fibers Multi-Mode Fibers
Core diameter 50 or 62.5 µm, so there is space for multiple modes adequate attenuation and bandwidth for short haul applications.
Dispersion is the spreading of a light pulse as it travels down a fiber (Chromatic and Modal dispersion).
Bandwidth is the amount of information a fiber can carry so that every pulse is distinguished by the receiver at the end.

Selection of Optical Fiber Cables Fiber types
What fiber types are applied in optical transmission systems?
Optical Fiber Cables
Selection of Optical Fiber Cables Fiber types
In general multimode fiber continues to be the most cost-effective choice for enterprise applications up to 550 meters.
Single mode fiber is best used for distances exceeding 550 meters.

Indoor & Outdoor (Universal) cables:
Both Loose Tube and Tight Buffered fiber constructions, but always Halogen Free materials
Optical Fiber Cables
Selection of Optical Fiber Cables Construction: Halogen free ?
Halogen free material does not contain: Chloride, Fluoride, Bromide and Iodide
Advantages in case of fire: Less poisonous gases
(PVC generates hydrochloric acid) No release of caustic acids Less impairment to vision
Legend: FRNC = Flame Retardant Non Corrosive LSZH = Low Smoke Zero halogen LSNH = Low Smoke Non Halogen

Selection of Optical Fiber Cables Construction
Halogen free Jacket:
a unique selling point – why? Suitable for outdoor application Suitable for direct burial A good resistance to UV light
(in compliance with ISO 4892-2) Jacket is both FRNC and LSNH
FRNC = Flame-Retardant, Non Corrosive
LSNH = Low Smoke, Non Halogen
