What are you doing to do with it? If you shine light down the fibre yourself you can use WDM to increase the ROI on that fibre. If you buy a Layer 2 service for example from a carrier you can't scale along the same axis. If you are buying multiple cores the price formulae changes. Someone already mentioned the fibre tax, which is a sting. Generally I would expect lit fibre to be cheaper depending on what you are buying exactly. If you are buying a layer 2 ethernet circuit (just a pseudowire for example) from a carrier that is usually way cheaper than dark fibre. If you are buying a wavelength then there isn't usually a massive difference. Don't forget though if you have to lite it yourself that could encure loads of a extra capex, depending on what you want to do with it. Have you considered the diversity of the fibre? If you want a resiliant service (in the future, or maybe this is a second circuit to go alongside an existing one) it's usually cheaper to get another layer 2 service from another provider who is using differnt ducting et al. to get path and carrier resilaince (always check with a microscope fibre routes, often the person selling the fibre/circuit is mistaken when comes to ducts entering a building that end up sharing with other providers).
