Getting the most from optical fibers

• The most cost effective PON - point to multipoint
  architecture uses splitters, WDM and TDM.
• WDM drives the need for a broader operating
  window.

4
Low or Zero Water Peak Fiber

• Historically the 1383 nm had to be avoided by
  system designers. New processing techniques have
  eliminated the water peak and the entire 1280
  to 1625 nm region is available.

Single Mode Optical Fiber
PureAccessTM Ruggedized FTTH Fiber

• Reduced bending characteristics
• Improved environmental robustness
• Bend fiber tubes tighter
• Less sensitive to human error
• Splice compatible to PureBand fiber
• Ideal for Drop cables Jumpers

7
Improved Fiber Geometry

• Improved fiber performance.
• Reduced need for core alignment splicing. Less
  expensive and easier V-groove alignment can be
  used.

Cable Jacket Materials

• Polyethylene good UV resistance
• Medium Density easy entry
• High Density lower coefficient of friction
• Flame Retardant required inside buildings
• PVC poly vinyl chloride
• Flame resistance
• Abrasion Resistant
• Used for Riser Cable Yellow Single Mode, Orange
  Multimode
• Cross Linked Polymers
• Used in the presence of high electromagnetic
  fields
• Flouro Polymers
• Plenum cable for use above drop ceilings
• Steam Tunnel Cables

Key to all OSP fiber cablesExcess Length
11
Loose Tube Features

• Reverse Oscillating Lay - ROL
• Adequate room for excess length required in high
  tensile environments.
• Dielectric or armored options.
• Note The central strength members provide much
  of the stability. Therefore, they need to be
  anchored in all closures per the closure
  instructions. Also long lengths of un-cabled
  loose tubes will shrink and may experience loss
  increases.

Air Blown Fiber FutureFLEX System

• Reconfigurable Pt-to-Ptcabling system
• Transition between indoor outdoorwithout
  splices
• Non-disruptive
• Defer fiber costs
• Upgrades less than1/10th conventional

All Dielectric Self Support
15
Central Tube Cable

• Available in both Ribbon or Bundle subunits.
• Higher fiber density typical.
• Extended fiber count range thru 864-fiber.
• Peelable ribbon matrix material for easy
  termination.
• Cost Saving benefits of mass fusion splicing.
• Restoration and Network downtime reductions.
• Eliminates many thermal shrinkage issues inherent
  to Loose Tube buffer tubes.
• Dielectric Armored Construction
