Mr. Peter McCarthy:

I appreciate that some of the terminology we have used today is somewhat industry-specific and it is appropriate to define what dark fibre is, because what we are talking about is dark fibre. Dark fibre is the physical fibre optic cable and one must consider that it is a physical infrastructure product. Some refer to it as "unlit fibre" because physical infrastructure does not carry a 1 Gbps service, which is referred to as a "managed service". Managed services are where one puts the electronics on it and the dark fibre is the cable product.
