Major Characteristics Of Optical Switching Devices
A major application for these new switches was supposed to be in dense wavelength division multiplexing.To squeeze more traffic into a network, none of the strategies is tantamount to deploy DWDM, A programmable DWDM. Add/drop node "drops" one or more wavelengths out of a multilaterally channel and reroutes them to a different destination while potentially "adding " traffic from another source to the channel.
One of the most impressive optical switches was a 1152*1152 OXC for Xros.The product was supposed to be in the market in 2001.Another player was electron a spin-off company from the University of Essex.Most major player in MEMS Optical Switch were baking the traditional micromicron approach,but Agilent Technologies has a fluidic approach based on its ink-jet technologies has a fluidic approach based on this in-jet technology,In the Agilent switch,bubbles deflect the light between criss-crossing waveguides ,and at coring ,liquid crystals are used.The four most popular optical switch approaches are compared.
It was expected that optical switches would achieve full commercializatino by 2004.The great promise that these truly enabling MOEMs devices sem to offer was at firtst walidated by the acquired by Nortel Networks for $3.25 billion in stock;lntellisence,67% of which was acquired for $500 million by coring and cronos Technologies,However ,as we more than 10 billion dollar investment by these large Optical Switches Manufacturers in 1999-2000 became a texbook example of "irrational exuberance".There were not sufficient customers for the more than eight start-ups, and the three largest investing companies pulled back.What was still the all optical switching market, in the period between 2002 and 2004, was littered with the broken shells of startups that often tried to survive by doing seems optical switch foundry work.
Today, some surviving MOEMS companies, building all-optical switches, are successfully targeting more modest switch applications; say, for apartment building or university switchboards, and new emerging applications such as semiconductor test equipment.Companies such as Glimmerglass say to have solved the problems previously associated with the MOEM switches and maintain that their optical switches are more reliable, less complicated and more, and more cost effective.The reflexion eighty switch pack of glomerulus acts as either trivial core module tailored for communications systems manufacturers or as larger evaluation system.The evaluation system includes the reflection module, as well as ocular channel power monitors, a fiber patch panel and an ethernets's control interface.It is properly packed into a 4.5-by 9.5-by 7.0 inch racks -mountable case that consumes just 20w.
As we saw above, instead of switching signals among very large arrays of Fiber Optic Companies for telecommunications switches, TI targeted its digital light processing technology to projectors and video displays.Because it focused on the right mass consumer application from the get-to, TI's digital micrometer device turned out to be a big scale MEMs
