…such as video-on-demand. ITU-T Recommendation G.992.1 and ANSI Standard T1.413-1998 specify full rate ADSL. ITU Recommendation G.992.3 specifies ADSL2 which provides advanced diagnostics, power saving functions, PSD shaping, and slightly better performance than G.992.1. ITU Recommendation G.992.5 specifies…

…wavelengths per fiber. Gridless networking, which is enabled by the tuning capabilities of colorless networking, essentially throws out the ITU standard 50GHz grid and allows for more dynamic (and efficient) wavelength spacing. This allows for broader spacing if needed for high-transport needs, and narrower…

…Wavelength Selective Switch) or a combination of passive and configurable elements. The traditional terrestrial grid spacing is typically on the ITU 50GHz or 100GHz grids. A tighter grid spacing of 25GHz or 33GHz is also used today, such as submarine application systems. The goal is simple, squeeze…

…100GbE standards development in Peter Anslow.  Pete has over 30 years experience in the optical space, and is an active member of IEEE 802.3 and ITU-T SG15. Pete was kind enough to walk me through the topic of 100GbE and give some of his opinions on where the market may be headed.  Below is our…
