CSRZ-DQPSK format and high-speed device technology for achieving bandwidth compression and high sensitivity
October 2, 2006 Sometimes you need to have a physical reference to fully comprehend how big, fast or remarkable a certain achievement is, and that’s exactly the case with the truly astounding achievement of Japanese telco Nippon Telegraph and Telephone Corporation when it successfully demonstrated optical fibre transmission of 14 Tera bits per second over a single 160 km long optical fibre. For those who don’t know, the word Tera signifies one trillion and … you see, hard to wrap the brain cells around what that really means isn’t it. It’s why Apple talks about the iPod in terms of the number of tunes it holds. Then try this for size! That’s 140 high-definition movies per second, waaay ahead of the old record of 100 hi-def movies per second. Clearly we’re going to have enough bandwidth for high res anything a few decades from now.
