Fujitsu demonstrates optical components for 100G metro network
New services such as mobile broadband using smart devices, social networking, cloud computing, and on-line streaming have led to a rapid increase in the volume of communications traffic. This has created a great demand for 100G optical networks. The requirement for Core Networks to handle larger capacity and longer distance on their links has led to a spread of 100G optical networks using digital coherent transmission systems. The requirements on IP networks between data centers and metro networks to achieve larger capacity, higher port density, and lower cost has similarly led to the spread of 100 GbE optical networks.For core network applications the100G Coherent Transceiver defined in the OIF 100GLH-EM specification for long distance and high capacity transmission systems has been deployed. For metro network though a smaller size, lower power consumption and lower cost coherent transceiver is required.
