Handbook of Fiber Optic Data Communication: A Practical Guide to Optical Networking

Language: English

Pages: 468


Format: PDF / Kindle (mobi) / ePub

The 4th edition of this popular Handbook continues to provide an easy-to-use guide to the many exciting new developments in the field of optical fiber data communications. With 90% new content, this edition contains all new material describing the transformation of the modern data communications network, both within the data center and over extended distances between data centers, along with best practices for the design of highly virtualized, converged, energy efficient, secure, and flattened network infrastructures.

Key topics include networks for cloud computing, software defined networking, integrated and embedded networking appliances, and low latency networks for financial trading or other time-sensitive applications. Network architectures from the leading vendors are outlined (including Smart Analytic Solutions, Qfabric, FabricPath, and Exadata) as well as the latest revisions to industry standards for interoperable networks, including lossless Ethernet, 16G Fiber Channel, RoCE, FCoE, TRILL, IEEE 802.1Qbg, and more.

  • Written by experts from IBM, HP, Dell, Cisco, Ciena, and Sun/ Oracle
  • Case studies and ‘How to...’ demonstrations on a wide range of topics, including Optical Ethernet, next generation Internet, RDMA and Fiber Channel over Ethernet
  • Quick reference tables of all the key optical network parameters for protocols like ESCON, FICON, and SONET/ATM and a glossary of technical terms and acronyms

fibers emerge such as the OM4 multimode fiber. When the total bandwidth in a system becomes very large, such as in high-performance computing (HPC) systems, a large amount of links is required. This implies large costs for the transceivers, the fibers, and especially the fiber-optic connectors in the system. Today’s large fiber count connectors can hold up to 72 fibers [4] but at the expense of increased assembly yield challenges. For distances beyond a few hundred meters, single-mode fiber

optical source to be employed with PMMA-SI-POF. LEDs are available for all the main wavelengths (red, green, and blue) and can guarantee high output power and long lifetime. Components with an output power of up to 16 dBm can be found on the market and modulation bandwidths usually are on the order of the tenth of megahertz; thus, they usually are suitable for low-speed transmissions, such as 10 Mb/s, or in alternative require the adoption of complex modulation formats or signal processing for

about the “affinity” of application components in order to provide good performance. In addition, it helps prevent resources in a data center from becoming stranded and not efficiently usable. Flatter networks also include elimination of STP and LAG. Replacing the STP protocol allows the network to support a fabric topology (tree, ring, mesh, or core/edge) while avoiding ISL bottlenecks, since more ISLs become active as traffic volume grows. Self-aggregating ISL connections replace manually

network state virtualization. The IEEE 802.1Qbg standard is used to facilitate virtual environment partitioning and VM mobility. The state of the network and storage attributes must be enabled to move with the VMs. This addresses the previous concerns with high capital and operating expense by balancing the processor workload across a wide number of servers. This approach also reduces the amount of data associated with a VM through VM delta-cloning technologies, which allow clients to create VM

cable with a maximum of two repeaters in a single collision domain if maximum cable lengths are used. Cable lengths can always be reduced to get additional repeaters in a collision domain. With traditional 10BASE-T Ethernet, networks are designed using three basic guidelines: maximum UTP cable runs of 100 m, four repeaters in a single collision domain, and a maximum network diameter of 500 m. With 100BASE-T fast Ethernet, the maximum UTP cable length remains 100 m. However, the repeater count
