I was told by the Octotel guy last week, that when they dig up the road, the terms imposed on them by the CoCT are that any other company must be given the opportunity to put conduits in the same trench. This makes sense, because digging up the road multiple times would be madness.
AFAIK they are then given 6 months exclusive lead time, after which other companies can blow fibre through their conduits in the same trenches.
I've been told that is what they WANT to try and achieve yes (something similar). I am yet however, to see one instance of where this is actually happening.
The problem with this, is that there's no cost imposed on CoCT's attempted solution. So, ACME nuts and bolts dig up the trenches, and now ACME Tooth Fairy comes and say OK. You're digging, here's my ducts - let's put it in. Nothing stops ACME nuts and bolts from charging ACME Tooth Fairy (which is reasonably expected) to install the ducts on their behalf, in their trenches. That's all nice and in theory, yes, it works.
However, as the industry isn't regulated, and as costs aren't set in the relevant acts, nothing stops ACME nuts & bolts from charging ACME Tooth Fairy, R2K per meter, to install their ducts. Unfortunately, that is precisely what is happening too.
It is therefore, cheaper for ACME Tooth Fairy to just trench again, instead of using CoCT's "idealistic" and "opportunistic" methods to get them to share... The simple fact of the matter, is that these guys WILL NOT share openly, nor fairly, until they are forced to do so.
Hell, how many years later, and we're STILL waiting on Telkom to share the local loop through LLU. It's never going to happen.
