How do fibre optics transmit light? This is one of the questions for a science assignment and I really can't find an answer. I have found many websites explaining about fibre optics but they are too hard to understand. I would appreciate if anyone can help answer me this question in simplest form. Thank you!
how is do they make the glass wire for fibre optics? How is the actual glass that is used in fibre optic wiring made? The glass has to be near perfect so that it wont crack when bent, plus its incredebly thin. What Type of machines, or tools do they use? Images and sources would be incredibly helpful!

What is the best way to design a network that contains a fibre optic backbone, 4 subnets and and net access? I currently have a fibre optic backbone connected to the internet through a dmz. THere are two hubs on the backbone, each connected to a router. Each router then connects to 2 switches which will eventually make a total of 4 subnets containing computers and printers. Am i using the right network devices here? Ok, i have a DMZ sitting in between the internal network and the internet to provide security. In the DMZ is a web server, email server and a Remote access server with a firewall sitting infront of it keeping unwanted users out from the internet Could i put the two routers onto the backbone, then connect the switches to these routers to create my subnets.(i thiink thats what you were suggesting) Im going to use private ip addressing using dhcp and dns servers. I dont think i will need NAT as the workstations on the network dont need to connect to the internet directly, although they will be connecting to a WAN that contains another site. thanks for your help

Please help with advice on Virgin fibre optics broadband in UK !!? (1) - Do any of you have FIBRE OPTICS Virgin Broadband ---(not copper b/band but fibre optics Virgin broadband) ?! I have BT and it is OK but Virgin claims that with optical fibre, and that they are the only ones in the UK with fibre optics, they can offer up to 20 Mb speed. It is the "up to" I worry about. I wish to ask those with personal experience to give me advice. They make fantastic claims.... and I don't believe them, LOL. They say that ALL other ISP's use copper (true) and that therefore cannot offer more then 4 or 5 Mb speed. Virgin also say that with copper cable the distance from the exchange reduces downloads speeds a lot but that with Virgin fibre optics the distance from the exchange is completely irrelevant. Do any of you have Virgins B/band and if so, can you really download a song in a couple of seconds, and movies in a few minutes ? How close to the claim of 20 Mb speed ? Thanks a lot
Printer with fibre optics connection? I cant get a printer to work it's a HP laserjet 1300n. Basically I got the correct driver went to install and the device wont be detected, It's going through an old laptop and it connects via the network cable. It works well on one of the other computers but I've never installed a printer with a fibre optics connection. Halp! I'm a techi, it's at the college I work at. It's not shared it's directly from the tower to the printer. The other computer used an uncoventional connection that had an adaptor to a fibre optics chord that went straight into the back of the computer

How do I justify the choice of copper, optical fibre and radio links for the transmission? How do I explain how a television signal might be distributed around a block of flats using copper cables, giving a justification for this choice of transmission medium including in my own explanation why UHF to VHF/VHF to UHF conversion is necessary. Giving an explanation for using fibre optic distribution systems in hazardous environments. Explaining why a radio transmission system might be used instead of an infa red transmission system.
