I would make the single suggestion, when comparing fibre and copper, to omit or else clarify the "speed of light" references.<br><br>Here's how I compared the three terrestrial technologies in a recent article (slightly redacted here):<br><br>Why is FTTP superior? Fibre has no bandwidth limit and lasts 60 to 100 years. Every broadband technology operates just under the speed of light, but a glass fibre can carry millions of distinct colours, each of which carries data. Only fibre offers limitless bandwidth with no appreciable signal loss, even between cities. No electrical components are required from exchange to premises, and the fibre is unaffected by floods or electrical noise.<br><br>Copper lasts just 30 years, says Telstra, so most taxpayer-built copper is now on borrowed time, and copper costs Telstra $1.3 billion annually to maintain. Copper bandwidth drops sharply with distance as the high frequencies are drowned out by line noise, even with wires twisted into pairs. FTTN cabinets can shorten the copper distance to traverse, but cannot fix water-damaged cables. To get faster speed, you must lay new copper and build ever more closely-spaced cabinets.<br><br>Likewise for the best wireless service, you deliver fibre to Wi-Fi access points, reducing data demanded of mobile phone towers. Fewer outdoor mobile towers are then needed and they are less congested.<br><br>Source: http://newsweekly.com.au/article.php?id=5583&s=PXfHMhFrancis Younghttp://www.blogger.com/profile/17629410691198862677noreply@blogger.com
