Recently PPC was asked to investigate solutions to the problem of a FTTH rollout with no space for microduct. The customer faced the challenge of deploying fiber to 10 high-rise apartment blocks, each containing 180 dwellings, within 2 years. Sounds easy, but factor into the equation that there is no option to add infrastructure and the fiber must be installed through the pre-existing, pre-populated PVC conduits hidden in the voids and screeds. Also add in that no machinery or cable blowing equipment is allowed on site. Then you really have a problem.
Unfortunately for network designers and installation engineers across the world, this scenario is all too common. A lack of foresight when future proofing network infrastructure has resulted in a critical need for fiber cable that can be retrofitted into existing conduit and ducting, often when this conduit is already populated with cables.
