Hello and welcome. I hadn't exactly thought of infrared, but indeed this category could easily find its way onto Mike's list, if he hires an assistant to help with the load. grin More to the point however, earlier I had intended to convey the notion of hybrid fiber wireless in the "lower end of the electromagnetic spectrum" <cough>, namely the wireless radio spectra in the gigahertzes. HFW would become a real issue if, and when (I believe this will occur), the cable operators are called upon, or ultimately forced, to open up some of their HFC optical spectrum through WDM. Of course, this would apply to the JOLTs, Air Fibers, OpticAirs, and Terabeams (et al) of the world, as well. At the present time, the cable tv multiple system operators (MSOs) are using one or two lambdas per physical fiber trunk, maybe some of them are using more, but they are not using anywhere near the potential of their trunks which join their head ends to their field nodes. I'm surprised we've not heard more squawking from the independent ghz radio operators about this yet, the way we've heard data CLECs going after the unbundling of ILEC outside plant resources. Assuming that the MSOs continue using black coax, which restricts their ultimate delivery to residences, then, and in reality (and even if they themselves do go to a FTTH architecture), the MSOs then have about n * ten-thousand times more capacity in place [n * 10^4, where n = the number of singlemode fiber (SMF) strands that they have in place] than they'll actually need for their own HFC purposes for the foreseeable future. In contrast, a single lambda in each direction that could be extracted from their fiber bundles, using 1996 variants of wdm technology (although a more current form of wdm scheme which would be more optimal through 2001-2 would perform much better) would be more than enough to supply several (dare I suggest a score?) of wireless providers with each of their neighborhood internet access and other traditional wireless distribution and collection needs. In Canada the cable operators are regarded as common carriers. Here, they are not. Not yet, anywho. Thanks for your input, and for being the inspiration for this post. FAC
