FTTx

With many oceanic optic fibre cables now available and even more planned for Africa and more specifically South Africa, Fibre to The home (FTTH) and business (FTTB) is becoming more of a reality. With the increase in available bandwidth and the spreading of fibre networks country wide it will, in the very near future, become a standard instead of an exception in South Africa. Currently fibre to the home/business is mostly deployed to areas such as Gated Communities and business parks especially in the larger metropolitan areas, where the higher density of population drives down cost of deployment.

Greenstone Networks are specialists in the design and build of FTTH/FTTB fibre optic Networks. These include E-PON, G-PON, and Ethernet Point to Point Networks.

Greenstone can consult from cradle to grave on the best concept to meet the client’s requirements. We will consult with the design, installation and implementation of the full optical fibre network; we can provide a bolt on rolodex of services which primarily include Voice, Video (IPTV) and dedicated high bandwidth data to the end user.

Combined with our revolutionary Miniflex™ product range we can minimize our intrusive time on site and bring installation costs down by at least 30% while providing a reliable robust, efficient solution that will be able to meet the client’s needs for generations to come.

Design & Consultation

Our design team will consult from the early phases of the project and help our clients decide whether they will need a PON or PTP network. We will do on site surveys with our clients to guarantee that the system is installed with the least impact to the environment and custom to our client’s requirements. We guarantee the most cost effective and efficient deployments possible.

Civil Engineering

By using our new Miniflex `Tuffduct’ and mini trenching techniques with the RT80 and RT100 machines, we can do the fibre route builds in much less time with much less disruption to the tenants. The machined trench is cut in the road or pavement, depending on surface preference being tar and concrete. We can cut 30-60mm wide by 100-350mm deep slots in the surface, drop our Tuffduct in, and then re-seal the surface in no time at all. For more information please see Civil Works.

What is the difference between PON and PTP systems?

PON: Passive optical Networks

Whether it is an E-PON (Ethernet PON) or a G-PON (Gigabit PON) the topology of the network consists of a single fibre distributed from the core distribution to a splitter unit where the light signal is duplicated up to 32 fibres each going to a separate dwelling or business.

Advantages:

  • Generally Cheaper costs,
  • Less optical fibre infrastructure required,
  • Simpler and less technology intensive system.
  • No Electricity needed at splitter units.

Disadvantages:

  • PON systems normally causes lower bandwidths for the end used as one fibre’s bandwidth has to be shared by 32 users,
  • All users have to be with the same ISP or Video Provider.
  • If any maintenance has to be done on the main fibre al 32 users will be affected.

PTP: Point to Point Systems

As the name suggests, the topology of a PTP system normally consists of a single fibre to each user. The costs of a PTP system can be reduced by distributing the optical fibre switches closer to the end user from where it will be distributed but this can only be achieved if it is incorporated in the early planning phases. PTP systems are normally more expensive to install than PON Networks as it requires a single fibre to each user and requires switching technology (that requires electricity) to distribute the fibre.

Advantages:

  • Higher bandwidths
  • With the higher and higher demand that is set on bandwidth this system is much more future proof
  • Each user can be with a different ISP
  • Maintenance to fiber will only affect one user.

Disadvantages:

  • Higher initial installation cost
  • Electricity needed at switching points
  • More complex electronics system to maintain

Conclusion

PON systems are ideally suited for urban gated communities where there is a high density of users in close proximity. It is especially suitable on larger developments where long distances exist between the Network distribution point and each cluster of users.

PTP systems on the other hand, are more suited to clients with higher demands on Bandwidth and especial works well in business complexes. Here distances from your active head end should not play a role.

As the requirements in bandwidth increases over time, with for instance the demands that high definition televisions /video are now creating, PON systems will however become obsolete as these high bandwidths cannot be provided. On the other hand, PTP systems are easily upgradable by simply replacing the Networking equipment at the head end, so in reality for a future proof installation we will always advise PTP network infrastructure roll outs.
