Title: OSP Cable and Drop Wire Selection


1
OSP Cable and Drop Wire Selection
  • OSP Expo
  • Tony Squires
  • Product Manager, Cable
  • Sumitomo Electric Lightwave

2
Topics
  • New Fiber Technologies
  • Improved Bend Sensitivity
  • Cable Principles
  • New Cable Designs

3
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.

5
Topics
  • New Fiber Technologies
  • Improved Bend Sensitivity
  • Cable Principles
  • New Cable Designs

6
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.

8
Topics
  • New Fiber Technologies
  • Improved Bend Sensitivity
  • Cable Principles
  • New Cable Designs

9
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

10
Key to all OSP fiber cables Excess 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.

12
Micro Duct vs. Air Blown Fiber
13
Air Blown Fiber FutureFLEX System
  • Reconfigurable Pt-to-Pt cabling system
  • Transition between indoor outdoor without
    splices
  • Non-disruptive
  • Defer fiber costs
  • Upgrades less than 1/10th conventional

14
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

16
Topics
  • New Fiber Technologies
  • Improved Bend Sensitivity
  • Cable Principles
  • New Cable Designs

17
Time Saving Cable Designs
  • Dry cables using water blocking yarns and tapes.

18
Modular Ribbon
  • 3 robust 4 fiber ribbons are encapsulated to make
    one 12 fiber ribbon.
  • Designed to accommodate 4 fiber splits from
    feeder cables.
  • Splice compatible with conventional 12 fiber
    ribbons
  • Split by hand or splitting tool.

19
