IPSL: 40Mbps Over Copper - Cheaper to deploy than VDSL?Cheaper to deploy than VDSL? (old news - 02:11PM Tuesday Jan 29 2008) tags: dsl · business · alternatives · bandwidth · networking Rim Semiconductor Company is the latest company attempting to milk copper, and says their new Internet Protocol Subscriber Line (IPSL) specification is able to deliver 40Mbps of bandwidth over 5,500 feet of copper phone line. "Our technical team will continue to push the boundaries of data transmission across copper wire because 1.4 billion existing copper-based end users require it," insists the company. The company's draft Release 1.0 of the Internet Protocol Subscriber Line' specification calls for a semiconductor to drive data at fiber-like speeds over the existing copper telephone lines. In line with the draft specification, Rim Semi's Cupria' transport processor is now able to drive data traffic at 40 megabits per second (Mpbs) 5,500 feet (1.67km) on 26AWG (0.40mm) telephone wire. Existing technologies are able to drive data 15 mbps at this distance on this wire type. The company's website insists that IPSL will cost half as much to deploy as VDSL, and is ideal for IPTV -- though they're still only offering 26Mbps at 6,000 feet over IPSL according to their product documentation (pdf). Rim has been testing their IPSL solution at Monroe Telephone in Monroe, Oregon (100 miles southwest of Portland). |
