  5. Blolite for Telecom BLOLITE • The basic premises • Infrastructure costs (including down time, start up delay costs, maintenance, repair, upgrade, etc) will continue to grow in the future

  6. Blolite for Telecom BLOLITE • The basic premises • Growth in demand for bandwidth will continue to explode, with no foreseeable limit to it. • Optical fiber is the best communication element known today, therefore is the preferred solution for broadband, extensive telecom networks

  7. Blolite for Telecom BLOLITE • The shock of the future • When planning an infrastructure with long life cycle, the planners need to cope with the demands that the future will place onto the infrastructure. E.g., the german autobahns, designed during the 30’s, are still in use despite a dramatic change in transportation technologies

  8. Blolite for Telecom BLOLITE • The shock of the future • In the telecom industry, the rate at which future changes appear is measured in years, not in decades. • The shock of the future has a direct impact on the physical connecting element of a telecom network (copper or fiber cables)

  11. DWDM... Blolite for Telecom BLOLITE

  12. Blolite for Telecom BLOLITE • The three fiber questions • When to install fiber? • Which type of fiber? • How many fibers? • And a meta-question • How many times during the life-cycle of the infrastructure will we need to answer these questions?

  13. Blolite for Telecom BLOLITE "Taking the right decision today means not having to re-install optical fibres and/or copper cables tomorrow as they will then be simply blown-in!"

  14. Blolite for Telecom BLOLITE • Blown fiber Blown fiber was born when it was realised that the viscous drag of an air flow alows the fiber to literally ... … fly inside the infraestructure element

  15. Blolite for Telecom BLOLITE • Why use blown fiber • Cost distribution: first the infrastructure is put in place, the fiber circuits are installed only when required • The infrastructure can be easily modified/repaired • Fiber can be installed on demand, and new fiber types can be installed without changing the infrastructure

  16. Blolite for Telecom BLOLITE • Why use individual blown fibers • Reduced weight and increased surface = better performance, longer distances • Smaller diameter = better flexibility = tortuous routes (min radius for individual 5mm ducts = 25 mm) • Choose number and type of fibers at installation time, no special cables required

  17. Blolite for Telecom BLOLITE Fiber in the local loop For example: 6 buildings in a block 8 fibers per building Phased implementation / on demand 1 km perimeter(4x250m)

  18. Blolite for Telecom BLOLITE Fiber in the local loop With standard fiber cables it could be possible to add a cable to each subscriber the day it is required, … … but this implies a new complete installation for each subscriber

  19. Blolite for Telecom BLOLITE Fiber in the local loop It could also be possible to lay the complete infrastructure on day one, but … … this would be very costly, lots of dark fiber, and no future proofness, for an unknown demand

  20. Blolite for Telecom BLOLITE Fiber in the local loop It could be done with a ring, but then segregation points have to be prepared before hand, and segregation would take place over a “live” cable. And again, lots of dark fiber, no future proofness

  21. Blolite for Telecom BLOLITE Blolite in the local loop The secondary ring would be installed, made of a number of microducts, on day 1. From there, any new customer would require a segregation and a blown fiber installation

  22. Blolite for Telecom BLOLITE Blolite in the local loop Segregation takes place on empty ducts and can be made on demand No dark fiber exists No increase in the number of fibers or change of fiber type affects the infrastructure

  27. digging: cost distribution Underground Construction (38,1%) Co-ordination, Site Supervision (9,1%) Manholes (3%) End units incl. installation (1%) Cable material (16%) Installation of cables (3,9%) Empty duct material (11%) Installation of empty ducts 4,2% Source: ALCATEL, City of Bremen, 250km … > 50 % are digging costs

  28. somethings are still there ...

  29. Underground Construction vs. No-Dig Technology (BOP) necessities/demands

  30. Comparison of Cable Installation Technologies
