Copyright(C) 1994 - 2009 Network World, Inc. http://www.networkworld.com/news/2009/052709-verizon-trials-100g.html Verizon Business took its next step toward deploying 100Gbps by trialing its 100G optical service with the United Kingdom's national research and education network, JANET. Brad Reed 2009-05-27T12:00:00-04:00 http://www.networkworld.com/news/2009/052109-researchers-use-nanotech-to-create.html Researchers at an Australian university used nanotechnology to create an exponentially more dense recording medium that could allow a DVD-style disc to hold up to 10TB in the next five to 10 years. Lucas Mearian 2009-05-21T12:00:00-04:00 http://www.networkworld.com/newsletters/lans/2009/051809lan2.html Motorola this week introduced its Passive Optical LAN technology for enterprise networks. At the Interop trade show in Las Vegas, Motorola unveiled POL, which brings gigabit passive optical networking, or GPON, to enterprise backbones.

GE says its breakthrough was achieved by writing 3-dimensional patterns that represent data onto a disc made of highly reflective material. The disc then acts as a mirror that makes it possible for a laser to pick up the entire piece of data. GE's process doesn't just put information onto the surface of the disc--as DVDs and CDs do--but etches the micro-holographic patterns below the surface of the disc as well. Ian Paul 2009-04-27T12:00:00-04:00 http://www.networkworld.com/news/2009/041609-if-blu-ray-is-dying-why.html Will Blu-ray finally get some respect? The high-definition optical disc format has long been the whipping boy of media pundits, many of whom predict consumers will spurn Blu-ray and gravitate instead toward video-on-demand, online download, and movie streaming services. Blu-ray is old school, they say, a relic of the bygone era of physical media, despite the fact that it bested challenger HD DVD in 2008 after a two-year high-def format war. Jeff Bertolucci 2009-04-16T12:00:00-04:00 http://www.networkworld.com/news/tech/2009/033009-tech-update.html Looking down the LAN road, the Terabit Ethernet milestone is very much in sight. While 3.2Tbps and 6.4Tbps speeds were demonstrated in test environments by Siemens/WorldCom and NEC/Nortel respectively starting in 2001, the first set of viable solutions are just now taking shape. Sreedhar Kajeepeta 2009-03-30T12:00:00-04:00 http://www.networkworld.com/news/2009/033009-netflix-raises-blu-ray-fees-time.html Buying a new movie on Blu-ray may be getting cheaper these days, but renting one is actually getting more expensive. Netflix has announced it's raising its Blu-ray surcharges, replacing the US$1-a-month flat rate introduced last fall with a new tiered alternative. Translation: Your bill will go up by anywhere from $1 to $8 per month, depending on which plan you've chosen.

Jeff Caruso 2009-03-26T12:00:00-04:00 http://www.networkworld.com/newsletters/lans/2009/020209lan1.html Never mind the current recession. This is just a hiccup that in only a small way detracts from the tremendousness of the continued growth of the world's communications infrastructure. Jeff Caruso 2009-02-03T12:00:00-04:00 http://www.networkworld.com/news/2009/020309-optical-chip.html Danish and Australian researchers have developed a chip that efficiently reads 640Gbps optical transmissions and could help pave the way to terabit Ethernet.
