It did not say anything about wiring fiber to the curb. the whitepapers stated that was an option. What would have to be done is put equipment at the node/tap and home. Not a singe thing of laying fiber clsoer has to be done. notice how the article states "For high-capacity residential broadband, the switch can be used in fiber-to-the-curb network designs, imitating passive optical network (PON) systems but at a lower cost, according to Narad. For fiber-to-the-curb applications, the Narad switches can be placed at existing coax cable taps where the fiber meets the coax connection to the customer. " Notice CAN BE USED FOR FIBER TO THE CURB It can also be done without replacing the existing coax with fiber. Think of this equipment like you are replacing a hub with a Switch

" Notice CAN BE USED FOR FIBER TO THE CURB It can also be done without replacing the existing coax with fiber. If they dont do fiber to the curb then they can't offer all customers anywhere near 100Mbps/100Mbps. If coax is used to backhaul multiple customers to the point in the network where fiber meets coax (e.g. not implement fiber to the curb) then all the customers downstream of that fiber/coax point are going to be sharing that coax segment. Narad can only squeeze so much additional bandwidth out of coax, I believe they quote 100Mbps. You can't have X customers running @ 100Mbps/100Mbps sharing a 100Mbps backhaul segment (unless you want really unhappy customers).

tmc8080 join:2004-04-24 Brooklyn, NY Reviews: ·Optimum Online ·Verizon FiOS	Narad would seem to sell cablecos a version of the sun, moon and stars fttx switches that can cook dinner, babysit your kids and make you look younger at the same time! Its not rocket-science and is technically old technology (5+ years). The point is that cablecos have NOT had a REASON to buy the stuff. Losing 40% penetration of their markets in broadband is a good reason (to the tune of a few million per year revenue). Unfortunately, both cablecos and telcos are looking VERY carefully at 'the issue of' ramping up speeds cautiously to allow leveraging their last mile for CONTENT they SELL to the consumer "PRE-LOADED" like a holodeck simluation in the consumer's minds. see net-neutrality debate Despite cableco upgrades that take 18-30 months depending if you count the 2 towns they deployed and opened within the first 3 months of deployment. Telco nodes can give 30/5 as the basic package without breaking a sweat. Beyond that, telcos have to upgrade ONT's to generation 2 and utilize gigabit ethernet for CPE interface. This is due to the fact that to properly deploy 100/100 you need 1000/1000 ethernet segment to properly get 80-99% of the bandwidth throughput due to overhead. Cablecos are not immune to giving customers NEW equipment for the increased speeds. Some analysts in the industry would say they haven't paid off the investment in the old equipment. Which is a plus for telcos, as DSL has a second halflife for customers who are on dialup. Show me a docsis 1.0 modem and I'll show you a door-stop. FYI, my MOBO has 1000 ethernet and cat5e can do 1000/1000 decently in the range of 100/100. So, I'm ready! Just upgrade the ONT and send me that sweet 1000/1000 wanport router..
