![]() ![]() For example, 100GBASE-LR4 has four optical wavelengths of 25G on the fiber coming from 10 electrical CAUI signals of 10 Gbit/s on the host side. The new 40G/100G Ethernet architecture is based on the concept of virtual lanes or physical coding sublayer (PCS) lanes, which would get multiplexed and transported over the 4 or 10 parallel wavelengths on a single fiber. The IEEE 802.3ba standard defines a single architecture capable of supporting both 40G and 100G Ethernet, while producing physical-layer specifications for communication across backplanes, copper cabling, multimode fiber and singlemode fiber. ![]() This trend significantly stresses transport backbones, which have been built on 10G wavelengths, and is driving the need for upgrades to 40G and 100G. The key trend is toward IP-fixed/mobile network convergence for the delivery of voice, video and data applications with IP (and Ethernet) as a common universal platform fueled by the exponential growth of video, gaming, collaboration and cloud-computing applications. ![]() The combination of digital media, personal computing and global networking is creating a radical shift in the telecom industry. ![]()
