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

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 BLOLITE Blolite for Telecom

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) BLOLITE Blolite for Telecom

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? BLOLITE Blolite for Telecom

"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!" BLOLITE Blolite for Telecom

Blown fiber BLOLITE Blolite for Telecom 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

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 BLOLITE Blolite for Telecom

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 BLOLITE Blolite for Telecom

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

BLOLITE Blolite for Telecom 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 Fiber in the local loop

BLOLITE Blolite for Telecom 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 Fiber in the local loop

BLOLITE Blolite for Telecom 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 Fiber in the local loop

BLOLITE Blolite for Telecom 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 Blolite in the local loop

BLOLITE Blolite for Telecom 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 Blolite in the local loop
