whitepaper Radio-Over-Fiber Transmission of 1.25-Gigabit Ethernet Signal on 60-GHz Band Subcarrier With Performance Improvement and Wavelength Reuse2007-06-01 Institute of Electrical and Electronics Engineers
  With Radio-over-Fiber (RoF) enabled remote antenna, Gigabit Ethernet service operating at 60-GHz frequencies can be accessed cordlessly. Due to limited linear operation region of 60-GHz optoelectronic modulators commercially available so far, optical weak modulation is required leading to limited link performance. This paper demonstrates in RoF transmission of 1.25-Gigabit Ethernet signal on 60-GHz band subcarrier, the fiber downlink performance is improved by suppressing the optical carrier-to-sideband ratio based on the usage of a simple and low-cost fabricated 2×2 all-fiber optical interleaver. Simultaneously by using the interleaver, the downlink optical carrier is recovered and is reused as optical source for fiber uplink hence laser-free access point is achieved.

whitepaper Bredbaand Nord Launches Video Service Over Cisco IP Next-Generation Network2007-05-22 Cisco Systems
  Bredbaand Nord was established by three local utility companies wanting to invest in the development of Vendsyssel and Han Herred in Northern Jutland, Denmark. The company wanted to expand their capabilities beyond legacy services into new, complex areas such as delivering video, voice and data. Cisco along with the company Bredbaand Nord launched video services over a Cisco Internet Protocol Next-Generation Network (IP NGN) platform comprising a headend from Scientific Atlanta, a Cisco company and a Cisco Ethernet Fiber-To-The-Home (E-FTTH) network.

whitepaper SAN Fundamentals: How Fibre Channel SANs Are Built, Secured and Managed2007-04-01 Sun Microsystems
  This paper discusses the core technologies that are used to build and secure Fibre Channel based Storage Area Networks. Fibre Channel is a flexible standards based networking architecture that can be used as a transport mechanism for a number of Upper Level Protocols. The most common Upper Level Protocols are SCSI and TCP/IP. In this paper, the term Storage Area Network (SAN) is used to describe a Fibre Channel network over which SCSI-FCP (SCSI over Fibre Channel) Protocols run.

whitepaper SAS: The Next Evolution of SCSI2007-04-01 Sun Microsystems
  The Small Computer System Interface (SCSI) has enjoyed over twenty years as the defacto standard in the storage industry. SAS is the newest serial interconnect and successor to iSCSI. SAS has leveraged SCSI technology and improved upon it to offer an improved host interface, as well as drive technology, to meet these increasingly rigorous performance and scalability requirements. With a solid roadmap and industry acceptance behind it, SAS technology is proving to be the next evolution of SCSI. As a large proponent of leading technologies, Sun has been a leader in SAS with a range of SAS platforms available. The most recent of these is with the introduction of the Sun StorageTek 2500 series of arrays based on SAS technology.

whitepaper Chunghwa Telecom Expands and Improves Service for International Operations0000-00-00 Cisco Systems
  CHunghwa Telecom (CHT) is the leading telecom service provider in Taiwan. Competition in Taiwan's telecom market has been increasingly intense after liberalization, and it is important for CHT to expedite its expansion into overseas markets. CHT selected a Cisco optical networking solution, using the Cisco ONS 15454 MultiService Provisioning Platform (MSPP), to help propel its rapid expansion into overseas markets in Asia, Europe and the United States. CHT also expects the Cisco optical networking solution to enhance end-to-end management of its customers' networks and improve services to the increasing number of Taiwanese Service Providers (SPs) and enterprises with global operations.

whitepaper Fiber to the Home Architectures2007-01-31 Cisco Systems
  The interest in deployments of Fiber To The Home (FTTH) is rising, particularly in Europe. Although initial FTTH deployments in Europe were mainly carried out by municipalities and utilities, large incumbent operators are starting to announce FTTH deployments. In the United States and Japan, FTTH deployments are mostly based on Passive Optical Network (PON) technology. Deployments in Europe include mostly point-to-point and ring-based topologies employing Ethernet technology, referred to as Ethernet FTTH, along with a small number of PON FTTH deployments. This paper discusses the different access network architectures, explores the access protocols being deployed, and provides an overview of their respective characteristics.

whitepaper Sharing FCP Adapters Through Virtualization2007-01-11 IBM
  The IBM System z9 and its predecessors pioneered server virtualization, including the sharing of data storage subsystems among the virtual servers of a host computer using the channel-sharing capabilities of FICON channels in Fibre Channel (FC) fabrics. Now industry-standard Small Computer System Interface (SCSI) devices in storage area networks must be shared among host computers using the Fibre Channel Protocol (FCP), and this has been problematic with virtual servers in a host computer. To apply the power of server virtualization to this environment, the IBM System z9 implements a new FC standard called N_Port Identifier Virtualization (NPIV). IBM invented NPIV and offered it as a standard to enable the sharing of host adapters in IBM servers and FC fabrics.

whitepaper Protection Networking of Ethernet PON FTTH Access Network2007-01-11 Universiti Putra Malaysia
  Massive deployment of FTTH fiber network causes protection to FTTH network a crucial need. Most FTTH access networks are protected from failure by having redundant network equipments. These are not economical approaches, as the redundant systems are not efficiently utilized by the network. In this paper, the authors propose a protection method where redundant equipments are not required and protection is provided to end user through sharing of bandwidth during the failure time. A protection control unit and an optical switch is employed connecting four Optical Line Terminations (OLTs) with each one serving only 32 Optical Network Units (ONUs).
