FIBRE FAQs

Here are a few ways in which we can help you on your journey:


Do I need a license to offer Fibre Connectivity services?

Yes. ICASA requires you to have the necessary licenses in order to provision and operate a Fibre network.

More information on the Licensing in South Africa can be found here.


Throughput testing – How fast can the network go?

Before you test just how fast your network connection is, remember that you are limited by the package by which you have purchased. Even if the equipment is capable of carrying higher speeds, you may be limited by the service you have subscribed to and may be subject to certain throttling or contention ratios.


What is the actual usable capacity of a particular network link?

You can get a very good estimate of your throughput capacity by flooding the link with traffic and measuring how long it takes to transfer the data.

There are a few good tools on the internet with the most common being http://speedtest.net/.

You must remember, though, that these tests do not allow you to test the speed of a given link, but only the speed of your link to a particular site on the Internet.


 

 

How dependable is Fibre connectivity?

Fibre systems can be designed to provide “5 nines” availability.

Anything that blocks the transmission path for a substantial length of time will affect performance. Properly designed systems are virtually unaffected by weather.

Design engineering includes an availability statistic which states a given percentage uptime. Design goals are so-called “5 nines” or 99.999% availability which translates into a few minutes annually.


Is Fibre only for the Internet, or can it be used for Voice as well?

Absolutely!

The degree of latency is very low since Fibre transmission travels at lightspeed, which makes this a perfect transmission for Voice communication.


How secure is Fibre connectivity?

It depends on what you’re sending and the system that you use. When it comes to IP, if the information may be encrypted before it is transmitted, then depending on the type of transmission, it can be very secure.

In some cases, the equipment you use can detect an attempt from a hacker and take appropriate action. In other cases, specific matches between transmitting data and receiving data are part of a design, so unless there is an exact match, hacking of data becomes impossible.

If security is a concern of yours, ask your provider what they do to ensure that your connection remains secure.


How long can I expect to wait to get service?

This really depends on the Fibre Provider (feasibility) and the internal process for applications.

Based on our market experience, this can take anything from 4 weeks up to 6 months – if even feasible for the provider.


What is Contention and what does it mean?

When a user is connected to the Internet using broadband technology they are sharing the connection infrastructure with other users.

The term contention is simply a ratio used to measure the extent of this sharing. The typical contention ratio for standard Fibre services is 10:1.

For example, on a package with the contention of 10:1, up to 10 other Broadband users may share the bandwidth in the same connection point.

Network operators can provide varying contention ratios since they own and operate our their network, and upgrading capacity on a sector to maintain a guaranteed contention ratio is relatively simple which enables the provider to guarantee its services levels.
